Or you might consider creating a ssh key pair for the remote root and login
directly to root with no password, only using the ssh keys.

Also good point, one can always do a "make oldconfig" on a new kernel
to recover specific tweaks.

Regarding backing up the portage tree, the binary packages won't do
much if the last sync is, say, one or two months old or even worse if
older. To use "emerge -K" one must have the same package version built
in the binary package as the one present in portage. That's what I'm
facing right now, it seems my binary packages won't be so helpful
after all - I'm beginning to think I'll have to go back to stage-3...

Re: [gentoo-user] Reinstall

[Francisco Ares]

Good day!

First of all, sorry for the late reply. I had to attend to a course a
bit far away from home and it was pretty intense.

Now, back home, I'll try the suggestions, thanks!

Just for the sake of preventing a future failure, besides personal
files (minimum and obvious) the "world" file and the binary packages,
built along with the package installation, what else should I backup
so that I would be able to quickly restore the same full working
Gentoo in a new hardware without having to work from stage3 up? The
portage tree is one of those items, for sure. But what else?

Thank you all and a good sunday.

[gentoo-user] Reinstall

[Francisco Ares]

Hello

After a main HD failure, I'll have to reinstall Gentoo from almost zero - I
have a full and recent copy of the /etc directory and the file
/var/lib/portage/world in a secondary HD (along many personal backups).

Installation basics done, now it is time for an emerge world.

Although the emerge lists is as huge as expected, it doesn't even start,
portage says there are cyclic USE flags that I should avoid at the first
moment, but may restore afterwards.

But it doesn't say which are those USE flags that block each other.

Is there any way to find those better than brute force?

By the way, I also have a copy of all binary packages (I always use the -b
flag while emerging any package) in that second disk. But that didn't help
so far, even trying to use the -K flag. I thought on un-tar'ing those
binary packages by hand, but portage will be unaware of this, not knowing
the packages are installed.

Any hint will be greatly appreciated!

Thanks

Thank you for your reply, Ashley.

In fact they are really errors, not warnings. It doesn't build to the end.
But that's something weird, the compilation don't stop at the first error.

Here is the set of files recommended in such cases, including the build
log, environment, etc.:

https://drive.google.com/open?id=1puc5-tj1a1-joQ0dDiL5ls17BOjjhwzh - they
are just plain text files, just the build log contains escape characters to
show colors in a terminal.

I suppose I should fill out a bug report.

[gentoo-user] Anyone seeing tons of build errors while compiling sys-devel/autogen ?

[Francisco Ares]

Hi all,

Just to make sure this ain't purely local: while building
sys-devel/autogen, the build process shows a lot (really) of error messages
from the compiler.

Is there anyone seeing something like this?

This system has quite an old Gentoo instalation, and some packages show
complaints about kernel features.  So I thought on doing an overall check.

[gentoo-user] Pre-merge checks

[Francisco Ares]

Hi, All.

I would like to see all pre-merge checks prior to build a new kernel, just
to make sure all kernel configurations needed até satisfied.

I thought on issuing an "emerge -e world" then interrupting the process at
the beguinning of the first package build.  But this looks a weird way of
doing things.

Is there any other way?

Another thing to be considered is S.M.A.R.T. activity, that is proper to
the hard drive firmware.  Don't know if it is safe or not to power it down
during that process though.  I would wait until it really finishes all
activity.

But do you really need to power it down?  Mechanic (magnetic) hard drives
are known to have shorter lives if they are turned on and off frequently.
My desk computer is rarely turned off, I have 4 hard drives, the oldest is
close to 10 years old and SMART diagnostics are always good.

Here goes my "me too". Nouveau drivers causing locks in the graphics
environment, locking also the keyboard, disallowing me to switch to a
common non-graphic terminal to try something.  I had to install a ssh
client app in my smart phone so I could try to unlock the system (with no
success) and, at least, shut it down gracefully.

I'm also a KDE user.  I've noticed more locks while using "chromium", but
this might have been a coincidence.

This usually ends up with too many resumes, but at least it gets to the end

[gentoo-user] xinput_calibrator on ARM (Odroid XU4) refuses to output to xinput

[Francisco Ares]

Hi,

I'm trying to use an eGalax touch screen in this Odroid, using
xinput_calibrator like this:

$DEVICE_NAME=`xinput_calibrator --list | grep "eGalax" | cut -d\" -f2`
/usr/bin/xinput_calibrator --misclick 0 --device "$DEVICE_NAME" --output-type
xinput

doesnt work, xinput_calibrator outputs an error after the apparently
successful calibration screen:

ERROR: XorgPrint Calibrator does not support the supplied --output-type
Error: unable to apply or save configuration values

Any hints?  Is it expected on an ARM CPU?  I use it the same way in a x86
machine, and it works perfectly...

Thanks a lot!
Francisco

Hi, Peter.

Thank you for your experience.  In fact, as an "emerge -e" is quite
automatic, and I could let the system alone a whole weekend, I didn't worry
(nor had the time) to do it in parts to try to figure out which one would
succeed, in special because on the following monday it just _should_ be
working, or the launch of the new program version would be delayed (for
who-knows how much time) and would put my neck at risk ;-).

Best Regards,
Francisco

Hi All,

After days and days struggling, I finally upgraded to the newest stable
kernel and updated every package with a "emerge -e", just in case, twice!
Then, rebuilt the kernel again.

So, like a charm, everything got back to work as before.

Unfortunately, will never know what piece of code that issue was.

Thank you, and

[gentoo-user] strange behaviour in quite special case

[Francisco Ares]

Hi, All.

This is a rather special case, so I don't expect much, but who knows?

I've built a Gentoo x86-64 system for an embedded application.

Just after a lot of updates, which I am unable to track, it stopped working
as usual.

There is the development system, fully loaded of a lot of packages used for
development, and the production system, that don't need all of those.

There is a line in both systems in /etc/iniitab responsible for auto-login
the production system user and the programs we need running (in its
".bash_profile" and ".xinitrc"):

c6:2345:respawn:/sbin/agetty -a production-user 38400 tty6 linux

The development system starts a WindowMaker session, and the production
system starts a program that controls the rest of the hardware of this
embedded system, with an X11 graphical interface.  That runs normally when
simulated at the development system.

The development system runs smoothly.  The production system, after
removing the files from undesirable packages and creating a squashfs image
of the ripped-off root partition behaves strangely at boot:

It shows the initialization messages as expected, but when the auto-login
and the controller program start should take place, it completely stalls up
to I plug a USB keyboard and issue some times some of the key combinations
to change to a text console and back to X11 (Ctrl-Alt-F1 and Ctrl-Alt-F6);
 only then the things resume as expected.

As you might suspect, there is no keyboard for the production system ;-) .

As a matter of fact, I don't know where the stall take place, as when I try
to switch to a text console to see the logs, it switches back to X11 and
starts our program.  By the way, the logs just show that the events
occurred at latter times than expected.

Although the squashfs is read-only, some main directories are arranged in a
way that, using tmpfs mounts and unionfs with the read-only directory to
the read-write tmpfs directory to that main directory provide a way of
creating temporary files that has been working for a few years now.

For instance, in "/etc/fstab":

tmpfs   /.etc.rwtmpfs   defaults,mode=755
0 0
union   /etcunionfs
default_permissions,allow_other,use_ino,nonempty,suid,cow,dirs=/.
etc.rw=rw:/.etc.ro=ro  0 0

And there is a "/.etc.ro" with a copy of all files present in regular
"/etc" , a "/.etc.rw" directory to be mounted tmpfs, and the original
"/etc" directory, that needs to be there at boot, even before mounting all
this.

Does anyone have a clue?

Thanks!
Francisco

[gentoo-user] cleaning /var/lib/portage/world

[Francisco Ares]

Hello,

During the process of learning how to manage packages in our beloved distro
- and even after knowing how to, but due to being in a hurry - I have my
"world" package set a bit cumbered with package names that would not need
to be there, as they are dependencies of other packages, as some libraries,
for instance.

So I thought on finding out which of those packages could be removed from
"world", and I have come up with the following script, which results in 3
files in the "/tmp" directory:

- world_remove_candidates
- world_remove_candidates_reasons
- world

- the first is a simple list of packages found in "world" that _probably_
could be removed from "world";
- the second includes which packages depends on each of the above mentioned
packages;
- the third, the cleaned up "world", without overwriting the original.

But, after backing up the original "world" file and replacing with the one
built by the script, things don't work as expected, as a lot of packages
were orphaned, by checking with "depclean".

Anyone could tell me what did I miss?

Here is the script:

#---
#! /bin/bash
cd /tmp
if [ -e world_remove_candidate ]
then
rm -f world_remove_candidate
fi
if [ -e world_remove_candidate_reasons ]
then
rm -f world_remove_candidate_reasons
fi
for i in `cat /var/lib/portage/world`
do
A=`equery d $i`
if [ "a$A" != "a" ]
then
echo $i >> world_remove_candidate
echo "* * * * * * * * * * * * * "$i >>
world_remove_candidate_reasons
for j in $A
do
echo $j >> world_remove_candidate_reasons
done
fi
done

cp -a /var/lib/portage/world .
for i in `cat world_remove_candidate`
do
S=`echo $i | sed s+/+/+`  # this is to format the string
accorgingly to 'sed' (ugly, isn't it?)
cat world | sed -e /"$S"/d > world.x
rm -f world
mv world.x world
done

# the following loop is for announcing it has finished.
A=20
while [ "$A" != "0" ]
do
A=$(( $A - 1 ))
sleep 1
echo -n -e \\a
done

ls -halF world*
#---

Thanks for answering.

The hardware is a x86-64 mini-ITX board, nothing unusual.  Besides this,
I'm working also in a Odroid XU-4, but this is not the issue.

I'm using regular X11 video drivers, as this board has a regular Intel
chipset.

Explaining a bit deeper:

There is a development equipment, with dozens of development aids. As I
don't want those in the disk image for production equipments, I have
managed to do this by making a copy of the working root partition
directories and files, remove portage related files and directories from
this copy and, using the working partition as reference, rip-off unneeded
packages files, like this:

for i in `equery -C f dev-qt/qt-creator` ; do if [ ! -d "$i" ] ; then rm -f
/mnt/aux/gentoo/$i ; fi ; done

Where /mnt/aux/gentoo/ contains that mentioned copy of all files of the
development root partition.

The package "dev-qt/qt-creator" is just an example, there are several
others which have their files removed from the copy of the root partition.

Thanks and
Best Regards,
Francisco

[gentoo-user] a bit off-topic - minimalist Gentoo: X needs a kick to start

[Francisco Ares]

Hi,

I'm trying to build a minimal Gentoo image for an embedded appliance.
Everything - AFAIK - works good, but I need to key in Ctrl-Alt-F5  /
 Ctrl-Alt-F7 a couple of times  (F5 is just an example, just have to switch
off of X and back again), just then X shows up.

I have removed a lot of packages, in special the ones used in development.
GCC is still there, though.

Any ideas?  I know this is hugely vague, but, who knows if someone out
there hasn't gone through this before?

Thanks!
Francisco

[gentoo-user] [OT] build programs in other distros

[Francisco Ares]

Hi, All.

I've used a few distros, but mostly for curiosity. Being a Gentoo user for
... well, more than a decade, I'm used to build binaries in a very simple
way, that simply works for me.

So, I probably learned the way to do it using Gentoo, and nothing else.

Recently I tried to build one of my programs in an Ubuntu distro, and it
didn't build at all, messing library and include files names and locations.

How do real developers manage this? And why this difference happens, in the
first place?  Why mangle uper/lower case characters in library file names?

I guess that's why "autoconf" "configure" et al exists...  But never tried
to learn about them, so perhaps it's time now?

Thanks!

Best regards,
Francisco

[gentoo-user] GPU closed source libraries

[Francisco Ares]

Hi, All.

I'm trying to get Gentoo and xorg in an Odroid XU4 (hardkernel.com).

Most things are done, but there are a few glitches. I'm using the open
source xf86-video-armsoc, which does not provide GPU acceleration.

So, for instance, dev-qt/qtgui with USE="gles2" (just an example), it will
pull media-libs/mesa for 3d acceleration, although the proprietary library
(Mali drivers) would do so.

How would I avoid emerging media-libs/mesa in this example?

Thank you,
Francisco

I have cloned their git kernel repository, and built a new kernel (not yet
the initrd) as from here:

https://wiki.gentoo.org/wiki/Xu4#Installing_Gentoo_on_an_Odroid-XU4
(already updated a few details here, too)

The "boot.ini" configuration for the boot loader did present a
"net.ifnames=0".  Now I have removed it, but still could not reboot, I'm in
the middle of a "emerge -e world", as many files got corrupted because of a
power failure during a move operation from a media to another. Now building
also binary packages to keep them safe in another device.  And using a UPS
;-)

On that article about net interfaces naming, I found a workaround using
udev rules just for this period of implementation.

Thanks for your point of view about hardkernel, I'll keep an eye on them.

Thank you, again,
Francisco

Thanks for the tip.  I've checked in /etc/udev files and directories, and
there is no rule for naming interfaces.

Instead of removing "net.ifnames=0" from the kernel command line, I have
altered it to "net.ifnames=1". Gonna try removing it at once.

But, imho, Odroid is a good hardware, and I have learned a lot about Linux
- not Android - in their Odroid magazine. And their Ubuntu image works very
good. And, as always, there are a lot of guys in the community.

Thank you!

[gentoo-user] mixing predictable with old style network interface naming

[Francisco Ares]

Hi, All.

This is a bit odd, because of a non conventional hardware platform: Odroid
(Hardkernel).

But I guess overall rules apply to all.

I need a second network interface, the original and single one present on
the board is to be connected to a GigE camera, so I use a USB/ethernet
adapter to have SSH remote access.

I have set up the boot manager so that network interfaces would be named
according to the predictable names rules. If not, the USB/eth adapter gets
"eth0" if the device is present at boot, otherwise, it is "eth1".

But if I disconnect the USB/ethernet adapter to leave the system alone, and
after a while I need to take a look on what's going on and plug back the
USB/ethernet adapter, it comes up as "eth0" again.

Anyone could give me a hint on where to look at it?  Why the new interface
is named in a way during boot and another during normal use?

Thank you!

Well, I've had similar issue. I had gimp to resize the image to its double
(width and height, of course), filtered it a bit (edge enhancement) and
split the image in several ones for the regions of interest.

Of course, there might be an easier way ;-)

[gentoo-user] How to correctly handle multiple Qt versions (qt4 X qt5)

[Francisco Ares]

Hi all.

In thys Gento system, there are packages that still need Qt-4, while newest
KDE, for instance, needs Qt-5.

Even inserting entries in "/etc/portage/package.use" for the packages that
need qt4, the emerge still fails, arguing that the package needs Qt-4.

On this system, "qtchooser" has never worked propperly - as far as I could
understand it - so I'm used to manage the "default.conf" symlink at
"/etc/xdg/qtchooser/" - is it correct to do so?  If not, what should I do?

Thanks!
Francisco

[gentoo-user] qt-creator (and others) too slow

[Francisco Ares]

Hello, all.

Interesting thing: running QtCreator in another machine with no KDE (using
WindowMaker) it runs as expected.

On another machine, the main one I use, with KDE, QtCreator (and other
program, as stated on the subject) eats CPU resources and behaves real slow.

On this KDE machine, connecting to the first one via ssh and running its
QtCreator, it starts to behave like the original one from this machine.

Starting QtCreator from a terminal, it says:

libEGL warning: DRI2: failed to authenticate

Starting QtCreator directly on that other machine, that warning does not
show up.

Any hints?

Both machines run the latest stable versions of QtCreator, Qt:4 and Qt:5

Thanks!
Francisco

[gentoo-user] qt-creator (and others) too slow

[Francisco Ares]

Hi, all,

Just upgraded to KDE 5, Qt 5 (as full as possible) and now QtCreator
frequently uses almost full CPU, a quad-core i5-4430. Any change on the
IDE, even just passing the mouse cursor over elements of an opened source
code file, makes the CPU consuption to the high tops.

It also happened when I tried some widgets using plasmashell, like the
analog clock and the Desktop widget. The process "plasmashell" eat up all
available CPU cicles.

Could it be something related to more deep details inside Qt basis?

Turns out to find funny QtCreator's description on KDE menu: "Lightweight
IDE for C++ ...".

Any hints to find out what is happening will be highly appreciated.

Best regards,
Francisco

Yes, all users were already added to "video" and "plugdev" groups (and many
others, like "audio", "usb", "cdrom", "games", "mysql", "scanner" ...).  I
don't touch this file for almost a year.

Still blackness...

Yes, I was not sure on how to do that, so I used kcmshell5 kcm_sddm (inside
another window manager) to get to the same point.  Now it seems to me like
going round the Earth just to get to the other side of the block, but it
worked.

On KDE 4, it was ok, it mounted removable media in
/run/[username]/[medialabel] , as the users were already in "plugdev" group
and, just in case, the "disk" group as well - and they are there up to now.

Talking about "plugdev" could it be that removing parts of KDE4 in order to
replace them with parts of KDE5 removed any udev rules?

Going to look into this.

Thanks!

[gentoo-user] kde 5 and portable media mounting

Hi, All.

After some issues (some not yet solved, but on the way...), there is one
pretty annoying: regular users have to provide root password in order to
mount a flash drive, for instance.

Am I missing something?  Found some posts on the net, but none has given
enough light on the subject.

Thank you,

Sorry, forgot to add that have already done that.

But, as mentioned, even from bash, using "startx", the black screen is
there.

[gentoo-user] blank (black) screen on kde 5

[Francisco Ares]

Hi, alll.

After upgrading to kde 5 (plasma), there is a big problem.

No matter if I use sddm to manage user authentication, or common console
login to bash and then to X and kde, the result is the same, a black screen
with the mouse on it.

If I right-click on that blackness, a menu appears, the standard desktop
menu, offering so set up the desktop. If I choose this option, a title bar
with borders around more blackness appears. I am able to move that window,
but can't see anything in ou outside of it.

I have tried to setup kde 5 look and feel with every modules "kcmshell5"
could list, but no success.

I have seen several messages on the net with people having the same issues,
but no final solution to me. Have already created a brand new user, with no
possible wrong configurations from the past, and even so, just blackness.

At least, I could direct the X error messages to a file, and here it is:

Same issue here, I 've just un-merged the package containing those files,
then the automatic update took care of everything else - as it seems up to

... or you may provide checking points, like a script to run all "emerge
world" processes automatically,

Open source and Linux' software begins with the premisse you know what you
are doing, as if you issue a "rm -fR /" you will get exactly what you have
asked for, a dead system, no "are you sure?" questions will ring.

Those "craps" made me learn a lot!

For my experience, if the X server was rebuilt (either a new version, or a
simple rebuild because of many possible triggers, including USE flags
change, for example), then you need to rebuild all X drivers as well.

After I issue a complete emerge update, I run the following script (I have
a nVidia card) as root:

GentooSystem ~ $ cat ~/bin/xorg_rebuild
#! /bin/bash
if ! [ -e /root/.working ]
then
touch /root/.working

XORG_SERVER=`equery l xorg-server`
if [ "$XORG_SERVER" != "`cat /root/xorg-server.txt`" ]
then
EMERGE_LIST=`equery l --format='$name' xf86*`" "`equery l
--format='$name' "xorg*"`" "`equery l --format='$name' nvidia-drivers`
# EMERGE_LIST=`equery l --format='$name' xf86*`" "`equery l
--format='$name' "xorg*"`
emerge -vD --with-bdeps=y --keep-going --quiet-build
$EMERGE_LIST && \
echo $XORG_SERVER>/root/xorg-server.txt && \
echo $NVIDIA_DRVR>/root/nvidia-drvr.txt && \
rmmod nvidia 2>/dev/null && modprobe nvidia
fi

DRIVER="nvidia-drivers"
MOD="nvidia"
VIDEO_DRIVR=`equery l $DRIVER`
if [ "$VIDEO_DRIVR" != "`cat /root/video-drv.txt`" ]
then
EMERGE_LIST=`equery l --format='$name' xf86*`" "`equery l
--format='$name' "xorg*"`" "`equery l --format='$name' $DRIVER`
emerge -vD --with-bdeps=y --keep-going --quiet-build
$EMERGE_LIST && \
echo $XORG_SERVER>/root/xorg-server.txt && \
echo $VIDEO_DRIVR>/root/video-drv.txt && \
rmmod $MOD 2>/dev/null && modprobe $MOD
fi

rm -f /root/.working
fi


It uses three files, the first is used to signal to other scripts (that
uses emerge for some reason) to not try to do anything while other of those
scripts, including this one, is being run. That is "/root/working".

Another file is "/root/xorg-server.txt", that keeps the output of 'equery l
xorg-server', which is compared with up to date result of the same command.
If it is different, the script lists all installed drivers and re-emerges
them. Finally this same file is updated.

The same happens with the nVidia proprietary driver, using file
"/root/video-drv.txt".

Hope this helps.

Francisco

Hi, Andrew.

A cron job starts a "emaint sync" every day, by the morning, sends an
e-mail about what's new, and later on, another cron job starts a "emerge
world", and also sends an e-mail with the emerge log.

Yesterday, all of this went fine, all updates were built and installed just
as expected.

Now, by the morning, I've got an e-mail showing 216 possible updates. Some
regarding the new stable branch of Qt, but most regarding KDE.

Best regards,
Francisco

[gentoo-user] 200+ package updates!

Hi, All.

This is just to say "Congrats!"  to all developers of our beloved distro.
All individual package maintenance tasks and overall coordination efforts
are, as always, from my point of view, fantastic, but this orchestration
exceeds all I've seen.

Congratulations!

And, please, keep the good work.

[gentoo-user] Qt5 X Qt4

[Francisco Ares]

Hello All.

Although Qt 5 is at a stable version, not so many things have already
migrated to this newer version.

Even the new USE flags, qt4 and qt5 are still not completely capable to
switch to the desired Qt version prior to building, as, for instance,
"dev-util/cmake" and "app-doc/doxygen", I had to manually switch
"qtchooser" set up back to Qt4 before correctly re-building those, even
placing a set of "qt4 -qt5" use flags for both.

Another detail is the eselect module for qt graphics system. An application
built using Qt5 complains about OpenGL issues, and up to now I could not
find how to set up Qt5 to use raster mode, instead of OpenGL.

So, as far as my experience says, it is not a good idea to switch to Qt5 at
this moment.

Any thoughts on these (or other Qt related) issues ?

Thanks!
Francisco

Thanks, Neil.

According to this site:

http://nouveau.freedesktop.org/wiki/FeatureMatrix/

nouveau is not complete on OpenCL (not OpenGL) implementation.

Not sure if it could be enough, though.  Gonna do some tests...

[gentoo-user] Why sci-libs/vtk asks for media-video/nvidia-settings ?

[Francisco Ares]

Hi, and happy new year to all.

I have a not so old nvidia video board, but the recent closed source driver
complains, saying that I should stick to an earlier version:

x11-drivers/nvidia-drivers-340.93-r1 (it is recommended if I unmask it and
emerge a new one)

Then, in an excerpt from emerge -tpvuDN world:

What should I do?  Although not entirely satisfied in using a closed-source
driver, and as far as I know, the alternative xf86-video-nouveau isn't as

Thanks Florian, Jörg and wabe, it is finally solved.

It happens that I also had LINGUAS set in /etc/profile

So, as it seems, this setting bypasses all others.  I've had found that
"LINGUAS_pt" use flag trick before, in an old post, but as it didn't work
at a first attempt, and as the post was a bit old, I supposed that this
feature was not in portage anymore.

But now with 3 persons saying basically the same thing, I went deeper in my
/etc files.

The trick brought up by wabe was crucial, as I tried to include another USE
flag on the same "env" configuration; when I asked to rebuild tesseract,
the USE flag was there, but the LINGUAS wasn't. So I started to look for
other instances and found it in that /etc/profile file, edited in 2012,
probably when I first installed Gentoo on this machine as a newbie.

Going now into a full revision into /etc .

Thanks a lot!

[gentoo-user] LINGUAS issue

[Francisco Ares]

Hi, all.

My locale language is "pt_BR" (Brazilian Portuguese), and many applications
now support native translations.

And there is the "pt" possible LINGUAS entry, and there is no "pt_PT"
(Portugal spoken Portuguese), for instance, neither any derivatives for
other Portuguese speaking countries, which possibly have their own regional
differences.

There are a few applications that do not distinguish "pt_BR" from "pt" and
treat Portuguese language as simply "pt". An example is the OCR program
"tesseract", that builds language specifics according to the LINGUAS
environment variable.

Is there a way for specifying particular "LINGUAS" for individual
packages?  I would not like to have to build dozens of applications to
include "pt" to my "LINGUAS" definition just to have "tesseract" to include
my native language support.  I've found some old messages about this on the
net, but did not get any real solution.

Or should I ask the "tesseract" package maintainer to add "pt_BR" to the
available options?

Thanks a lot for your time,
Francisco

Just my 2 cents:

IMHO, high end video cards, OpenCL capable (CUDA for nVidia), will be more
and more used for intensive and massive data manipulation, like audio and
video (image) recognition, which will be (I guess) the base of the future
user interfaces.

So why not get ready right now?  ;-)

Me, too, a hardware guy, but having to learn high level stuff. Here at the
company that work for, we had a programmer a couple of years ago, that has
gone for a better opportunity. So I got his load.

Blinking a bunch of LEDs is where I started. The first ones with simple
transistors, resistors and capacitors, TTLs were next, and then, finally, a
Z80 with an UV EPROM, having to be programmed at the university lab in a
terribly monstrous gig - there was a teletype (remember those?) where a
paper tape had to be punched with the byte codes, hand assembled from
mnemonics, the tape transferred to another part where it was read while the
bytes been burnt to the EPROM; if one missed or twisted a byte, everything
had to be done again, program tapes being literally patched over and over.
Nowadays it all look very funny, but not at all on those days with a final
degree project deadline approaching ;-)

Thanks for the opportunity for an old story to be remembered.

Thanks, Alan.

Well, I have noticed that, for the few details I got an eye on, it will
take a good time for an deep dive in.

I will start to look into some RFCs and see how much can be digested. Also,
downloaded RUTE to read during lunch, alternating with some RFCs ;-)

Re: [gentoo-user] Re: [WAY OT] wanna learn networking internals

[Francisco Ares]

Thanks, James.

I already know C and a bit of C++, and that's why I want to understand
deeply about networking protocols, there are some tricks that I see some
device's closed source SDKs doing that I would like to reproduce. And
probably - if they worth it - publish as open source, of course.

Francisco

[gentoo-user] [WAY OT] wanna learn networking internals

[Francisco Ares]

Hi,

Sorry for such WAY out of topic message, but Gentoo users are also way out
of regular computer users.

I intend to learn more deep details about networking intrinsics, (packets,
ports, negotiation, UDP, multicast, unicast, TCP, ethernet, DHCP,
protocols, and so on) so I decided to recur to this list.  Googling the
terms, just gets me to network administration and equipment interconnection.

Any hints on web resources for this research?

~ $ ps -A | grep 5254
 5254 ?00:00:07 baloo_file
   
and PID 6699 doesn't show up any more, probably the process has
already ended.
   
Did I miss something? How do I set up Baloo? Looking on the net,
 I
only found how to set up a file
 ~/.kde4/share/config/nepomukserverrc
(that was nonexistent, which seemed strange), is there something
 else
regarding the database it might be willing to use?
   
Thank you all.

Reading your posts, it seems you don't really want this feature
 of
KDE.  Why not disable the thing?  I have this in make.conf:
   
-nepomuk  -semantic-desktop
   
So far, that has disabled the whole desktop search thingy, that I
 also
found to be a pest and never needed.
   
Just a thought, in case you wasn't aware.

Do you use kmail? I disabled nepomuk at one point and I wasn't
 able to
   access
my contacts on kmail. I think it's the same with baloo. And from
 what
   I've
read the plan is for more applications to use it so you may miss
   important
features. They recommend just disabling file indexing or adding
 your
   home
directory to the exclusion list on system settings, But after doing
   that I
still got that popup a few times until I okay'd it.
   
  
  
   I used to use Kmail until all this mess started.  I think the last I
   used Kmail was back in KDE3.  When I saw all this mess coming, I
   switched to Seamonkey.  Seamonkey does all my email stuff and I'm
 happy
   with it.  I do wish the sound notification thingy would work tho.
 Maybe
   I just need to sit down one day and try to figure out why it doesn't
   work.  Sound works everywhere else.  Still, it does what I really
 need
   without to much bloat.
  
   I installed KDE with the kde-meta.  It basically installs everything
 but
   the kitchen sink.  To be honest tho, I could likely install it in a
   better way that leaves out TONS of stuff I never use.  This file
 indexer
   thingy is one of the ones I have never had a need for.  If I want to
   find some file, locate, find and etc works for those rare
 occasions.  It
   is rare since I'm fairly well organized with my stuff.  Well,
 computer
   files at least.  My closet and shop is a different matter tho.  lol
  
   My point was that this can be disabled IF it is not needed.  If it is
   needed, then fixing it is the solution.  If it is not, disable it and
   shove the problem into the trash can.  ;-)

   Thanks to all that have posted.
  
   I tried a clean start:  I've deleted all related (at least all that I
   could find) files used by baloo (just kept some backup copies in a ZIP
   file, just in case).
  
   As expected, all of them are back, and also that popup window,
 requiring
   root password.
  
   I guess, now, I am (we are) looking on the wrong place, perhaps this
 is a
   global setting, not a user one.
  
   Going to check this out.
  
   Thanks again, and

Thanks, Dale, for your point of view.

But since I'm not the only user (my wife is forced to use it, too ;-) )and
I am the only one that knows how to use a command line session, for
instance, I still want to try to make this semantic desktop thing to work.

Found this:

!DOCTYPE busconfig PUBLIC
 -//freedesktop//DTD D-BUS Bus Configuration 1.0//EN
 http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd;
busconfig

  !-- Only user root can own the foo helper --
  policy user=root
allow own=org.kde.baloo.filewatch/
  /policy

/busconfig


Looks like there might be something related to what I am facing, isn't it?

Googling the file name, I got this:

https://bugs.kde.org/show_bug.cgi?id=339465
https://www.reddit.com/r/kde/comments/2ibdf7/what_is_baloo_file_watch_and_why_does_it_need/
http://www.linuxquestions.org/questions/slackware-14/kde-4-13-3-%5Balien%5D-annoying-kde-polkit-and-wallet-prompts-4175517244/

So, got back to the first and (as it seems) proper solution, but with no
effects, for now.

Perhaps I'll just wait and see future upgrades on baloo.  Meanwhile I will
try to filter more directories not to be indexed, and/or increasing the
limit on /etc/sysctl.d/97-kde-baloo-filewatch-inotify.conf by hand.

Thanks!

 Nepomuk, and now Baloo, want to open file-watchers on your system to get
 change-notifications directly from the kernel (filesystem driver), instead
 of
 polling the filesystem.
 This is actually better, performance wise.

 To avoid these message, I created the following file a long time ago:

 % cat /etc/sysctl.d/97-kde-nepomuk-filewatch-inotify.conf
 fs.inotify.max_user_watches = 65536

 Guess I will need to change the name of that file now :)

 Kind regards,

  Checking on the file pointed by Joost, I've found it on my filesystem),
 but
  there is another file, an almost exact copy, for baloo:
 
  ~ # l /etc/sysctl.d/
  total 28K
  drwxr-xr-x   2 root root 4,0K Ago 21 10:50 ./
  drwxr-xr-x 160 root root  12K Ago 21 10:22 ../

  ~ # cat /etc/sysctl.d/97-kde-*
  fs.inotify.max_user_watches = 65536
  fs.inotify.max_user_watches = 32768
 
 
 
  The first value (65536) is from 97-kde-baloo-filewatch-inotify.conf .
 The
  second (32768) is from 97-kde-nepomuk-filewatch-inotify.conf.
 
  So, the mystery goes on...
 
  Thanks,
  Francisco

 what does:
 % cat /proc/sys/fs/inotify/max_user_watches
 give you?

 My guess: 32768 (as that's the last one it will find)
 On my system I get 65536.

 I think if you were to remove the nepomuk file, it should work.

 --
 Joost



 Unexpected:

 ~ $ cat /proc/sys/fs/inotify/max_user_watches
 131072

 both as a regular user an as root.

 Going to search for this number on config files.

 Thanks for the clue.

 Francisco




Also unexpected:

~ # cd /etc
etc # fgrep -R 131072 * 2 /dev/null
apache2/modules.d/10_mod_mem_cache.conf:MCacheSize 131072
sane.d/sharp.conf:option buffersize 131072
sysctl.d/97-kde-baloo-filewatch-inotify.conf:fs.inotify.max_user_watches =
131072


I have logged out and back in, to check for the effects on that window
asking for root password.  It did show up again, and now the
file 97-kde-baloo-filewatch-inotify.conf has been changed.

Going to try again, after removing 97-kde-nepomuk-filewatch-inotify.conf.
Back soon...

 what does:

 My guess: 32768 (as that's the last one it will find)
 On my system I get 65536.

 I think if you were to remove the nepomuk file, it should work.

[gentoo-user] nepomuk gone, baloo enters

[Francisco Ares]

Hi,

In fact, I can only suppose there's something related to changing from
nepomuk to baloo:

Now, every time I log in, a window pops up asking for root password.  The
window title is PolicyKit - KDE and pressing the button Details, it
shows:

Action: Folder Watch Limit
polkit.subject-pid:5254
polkit.caller-pid: 6699

Looking for those PIDs:

~ $ ps -A | grep 5254
 5254 ?00:00:07 baloo_file

and PID 6699 doesn't show up any more, probably the process has already
ended.

Did I miss something? How do I set up Baloo? Looking on the net, I only
found how to set up a file ~/.kde4/share/config/nepomukserverrc (that was
nonexistent, which seemed strange), is there something else regarding the
database it might be willing to use?

Thank you all.
Francisco

 Nepomuk, and now Baloo, want to open file-watchers on your system to get
 change-notifications directly from the kernel (filesystem driver),
 instead of
 polling the filesystem.
 This is actually better, performance wise.

 To avoid these message, I created the following file a long time ago:

 % cat /etc/sysctl.d/97-kde-nepomuk-filewatch-inotify.conf
 fs.inotify.max_user_watches = 65536

 Guess I will need to change the name of that file now :)

 Kind regards,

 Joost



 Thank you, Joost.

 Best Regards,

Checking on the file pointed by Joost, I've found it on my filesystem), but
there is another file, an almost exact copy, for baloo:

~ # l /etc/sysctl.d/

~ # cat /etc/sysctl.d/97-kde-*
fs.inotify.max_user_watches = 65536
fs.inotify.max_user_watches = 32768



The first value (65536) is from 97-kde-baloo-filewatch-inotify.conf .  The
second (32768) is from 97-kde-nepomuk-filewatch-inotify.conf.

So, the mystery goes on...

 Just a guess.
 I think when you provide the root password 2 things happen:
 That value gets increased on the fly (inside /proc/sys/)
 And the baloo-file gets updated as well.

  You need fatresize, which doesn't appear to be in portage. The approach
  when reducing a partition's size is to first reduce the size of the
  filesystem, to slightly less than the final partition size for safety.
  Then delete and recreate the partition, with the same starting point.
  Finally resize the filesystem to fill the new partition.
 
  What tools do I need?
 
  The easiest way is probably to use GParted, which does all the hard work
  for you, just tell it the new size of the partition. It will also create
  the second partition for you, as a bonus.

 I've read good things about Parted Magic:

   https://partedmagic.com/

 AFAICT, it's a friendly front-end to parted (as is GParted), but also
 includes some extra abilities like cloning partitions and disks for
 backup purposes.

  (beside the way to backup the SDcard, reinitialize it, put 2
  partitions on it and copy back the stuff.)
 
  Given that you should backup any important data before resizing any
  filesystem, this may be the easiest method.

 I've had resize operations go pear-shaped on me.  I haven't seen it
 often, but I wouldn't attempt a resize without a backup copy of the
 partition involved.

Flash memory devices are tricky when you try do defrag, as there is extra
logic inside them to do the opposite: spread as much data as possible, as
to equalize the number of write operations - the main limit for flash
memory - for all sectors.

Most defrag tools do this by reading files to RAM, reordering them, erasing
the originals from the media, then writing them again, using no direct
sector access, leaving that to the operating system. And it works on
magnetic media, as it creates empty spaces suitable for continuous files.

So that extra logic may fool you, making you believe it worked, when it
didn't.

Considering this, as already said, I would copy everything to another
media, set up a new partition layout, format the new partitions as desired,
then get all data back to the new layout.

Just my 2 cents, of course.

Good luck
Francisco

[gentoo-user] Re: [OT} Intel D2700 processor + NM10 chipset - how to kernel config?

[Francisco Ares]

Hi again.

I've found something, it looks like Intel had outsourced the video graphics
part of this family of processors to Imagination Technologies, using their
PowerVR technology.

Besides this, there are recent posts in a few forums that talks about an
open source driver, on the way.

In Intel's website, I could only find a 32-bit driver, and the hint that it
was extracted from an older SDK.

Meanwhile:

http://community.imgtec.com/developers/powervr/graphics-sdk/

I guess that inside the SDK package there might be its driver also, as
suggested by Intel, going to try it right now.

 Hi,

 I have bought a cheap mini ITX board with an embedded Intel D2700
 processor and NM10 chipset, and the kernel I have built a few months ago
 doesn't even allow text mode console - meanwhile, among other things, I'm
 trying to find and strip out any frame buffer entries in the kernel
 configuration, so that at least a plain text console might be visible.

 Also meanwhile, a live CD (kubuntu) managed to get a VGA KDE running (no
 pure text mode console), but only using a large screen monitor, and
 exclusively using HDMI port (the same monitor did not work on VGA, and the
 board does not support DVI), so that at least I could check the full
 specification of the processor (`cat /proc/cpuinfo`) and all of the
 peripherals (`lspci -k`), so that I could build a better suited kernel.

 Any specifics on your minds about this hardware?

 Thanks!

I have bought a cheap mini ITX board with an embedded Intel D2700 processor
and NM10 chipset, and the kernel I have built a few months ago doesn't even
allow text mode console - meanwhile, among other things, I'm trying to find
and strip out any frame buffer entries in the kernel configuration, so that
at least a plain text console might be visible.

Also meanwhile, a live CD (kubuntu) managed to get a VGA KDE running (no
pure text mode console), but only using a large screen monitor, and
exclusively using HDMI port (the same monitor did not work on VGA, and the
board does not support DVI), so that at least I could check the full
specification of the processor (`cat /proc/cpuinfo`) and all of the
peripherals (`lspci -k`), so that I could build a better suited kernel.

Any specifics on your minds about this hardware?

Thanks!
Francisco

Re: [gentoo-user] Hard drive storage questions

 Howdy,

 I have a 3TB hard drive that I use for my /home partition.  I'm going to
 be having to expand this before to long, lots of videos on there.  The
 4TB is a bit pricey and I would end up having to expand that to before
 to long.  So, I got to thinking, why not buy another 3TB drive and just
 add that which would double my space.  I use LVM by the way.  I may try
 BTFS, (sp?).   Either way, adding a drive shouldn't be to much of a
 problem.

 On one hand, adding a drive would double my space.  It would also spread
 out my stuff in the event a drive failed.  On the other hand, one more
 drive to have spinning that could fail too.  These large drives makes me
 wonder sometimes.

 What do you guys, gals too, think about this?  Just add a drive or buy a
 larger drive and move things over?  Or is this a six of one and half
 dozen of the other thing?

 Dale



 P. S.


 Filesystem   Size  Used AvailUse% Mounted on
 /dev/mapper/Home2-Home2  2.7T 1.8T  945G  66% /home




I've already had my /home partition filled up, and it was just one of the
partitions on the only hard drive inside this machine.

Nowadays I have 3 more hard drives on this same machine, which makes 4
drives in total. None of them so big, though, the newest one is 1TB.

Now, talking about redundancy, if you worry about many - or all - of your
files, perhaps you should consider a RAID. Although expensive, it makes
one's mind more relaxed ;-) .  Basically, what I have seen is that many
people worry about backing up files when at work, but completely forget
about it on personal computers.

Best regards, and good luck!

  Hi, again.
 
  Both approaches have worked out. Masking Oracle's JDK and JRE was a good
  starting point, and later on, having icedtea-bin and icedtea-web marked
 as
  ~arch (and removing the mask for JDK and JRE) did the final trick.

 If you really don't want the Oracle JDK/JRE, leave the mask in place.

[gentoo-user] multilib - do I need it?

[Francisco Ares]

Hi,

How does one know previously which packages will require 32 bit ABI ?

I have two systems (among others) to consider: one is very simple, built
using as fewer packages as possible, it is the development system for an
embedded equipment, and it is 64 bit ABI only - no multilib;  the other is
a general purpose workstation, with lots of packages, and someday, by some
forgotten reason, I needed to install emul-linux-* .

Now I'm willing to change the profile to no-multilib, I have found that a
lot of packages require to be rebuilt for 32 bit ABI. Is there a way of
checking which are the packages requiring 32 bit ABI?


Thanks,
Francisco

I don't know if this has been already answered:

edit /etc/sudoers to include a line like the one bellow:

[gentoo-user] [OFF TOPIC] Qt Creator unable to access containers in debug mode

[Francisco Ares]

Hi,

Recently - but can't figure out exactly when - Qt Creator has become unable
to access Qt containers (where the STL ones work as expected) on the debug
panel.  It shows not accessible in place of the expected item quantity
for a QList, for instance, but for a std::vectorstd::string, it works,
allowing inspection of all items.

Any hints on what I may be doing wrong? The headers are all accessible, for
instance. Should I build Qt with debug symbols enabled, as recommended for
glibc?

Using current Qt 4.8.5, Qt Creator 2.8.1, gdb 7.7.1, gcc 4.8.3

Thanks!
Francisco

 I remember having a problem with old Creator that had to do with showing
 contents of variables. I don't remember the details though. I only remember
 that the issue was gdb. I was using a version that was not working
 correctly with Creator 2.8. I had to downgrade to an old gdb. 7.5.1, I
 think.

 I can't reproduce the problem anymore, since I've since switched to
 Creator 3 (now on 3.3.2.) This is rather easy to upgrade to now, as Qt5 is
 now in portage (although in ~arch.) If you want to upgrade, note that you
 can still develop for Qt4 just fine. Qt5 is only used to run Creator
 itself, it doesn't have any effect on the version of Qt you want to develop
 for.

Re: [gentoo-user] Re: [OFF TOPIC] Qt Creator unable to access containers in debug mode

[Francisco Ares]

Thank you all for those clues, pretty interesting.

For now I suppose it is a gdb thing, as QtCreator is able to show details
about STL containers as expected.

Going to fiddle in gdb a bit more...

   Try to print it from gdb cli, if it works you'll know the issue
 QtCreator,
   otherwise you're likely missing some symbols. You should always compile
 any
   development libraries with debug symbols.
 
  You don't need debug symbols for inspecting containers. They are not
  needed. The only reason for enabling debug symbols in Qt is if you want
  to step into Qt's code.

 Thank you. You do need symbols though, just not Qts for this specific case.
 There are many reasons why you should compile your development libraries
 with
 symbols besides stepping into the code. Such as getting a backtrace. Even
 proprietary (closed-source) libraries often make the symbols available for
 this reason.
