I too was wondering why a Toshiba HDD 1.8" MK2431GAH (4kB-sector), 240
GB I've recently obtained was slow:

-> time tar xfj portage-latest.tar.bz2

real16m5.500s
user0m28.535s
sys 0m19.785s

Following your post I recreated a single partition (reiserfs 3.6)
starting at the 64th sector:

Disk /dev/sdb: 240.1 GB, 240057409536 bytes
255 heads, 63 sectors/track, 29185 cylinders, total 468862128 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0xe7bf4b8e

   Device Boot  Start End  Blocks   Id  System
/dev/sdb1  64   468862127   234431032   83  Linux

and the time was improved

-> time tar xfj portage-latest.tar.bz2

real2m15.600s
user0m28.156s
sys 0m18.933s

These 4k-sector drives can be problematic when upgrading older
computers. For instance, my laptop BIOS would not boot from the toshiba
drive I mentioned earlier. However when used as an external usb drive, I
could boot gentoo. Since I have been using this drive as backup storage
I did not investigate the reason for the lower speed. I am happy to get
a factor of 8 in speed up now after you did the research :)

Thanks for your postings.

[gentoo-user] SIOCSIFMTU: Invalid argument

[Valmor de Almeida]

Hello,

I am getting a

SIOCSIFMTU: Invalid argument [ok]

message when re/starting eth0. I am wondering about that. The router's
MTU is set at 1500. Looking at the /etc/init.d/net.eth0 it seems the
inteface metrics should be calculated automatically.

Any ideas about where to look for the reason for the message? Additional
info below.

I have unmerged imagemagick from my system did a revdep-rebuild and
emerge --depclean but continue to get this output

[gentoo-user] gcc upgrade

[Valmor de Almeida]

Hello,

I just updated the portage tree and gcc was upgraded. I have set gcc to
the newer version

-> gcc-config -l
 [1] i686-pc-linux-gnu-4.3.4
 [2] i686-pc-linux-gnu-4.4.3 *

and I am trying to rebuild the whole system with

 emerge -e system
 emerge -e world

assuming this all goes without trouble (will take a while), should I
unmerge version 4.3.4?

Thanks,

One interesting thing on the new Ferrari. If I do

-> emerge --pretend --verbose --newuse --update --deep world

These are the packages that would be merged, in order:

Calculating dependencies... done!

Total: 0 packages, Size of downloads: 0 kB

However

-> emerge -evp world

[ebuild U ] x11-proto/scrnsaverproto-1.2.0 [1.1.0] 49 kB [0]
[ebuild U ] sys-devel/automake-1.10.3 [1.10.2] 936 kB [0]

Total: 536 packages (2 upgrades, 534 reinstalls), Size of downloads:
1,015 kB
Portage tree and overlays:
 [0] /usr/portage
 [1] /var/lib/layman/science

Where

-> revdep-rebuild --ignore --pretend --verbose

* Checking dynamic linking consistency
[ 100% ]

 * Dynamic linking on your system is consistent... All done.

and

-> emerge --depclean --pretend --verbose

>>> No packages selected for removal by depclean
Packages installed:   538
Packages in world:69
Packages in system:   50

Number to remove: 0

So emerge -evp is useful to get those last inconsistencies out of the
system.

I tried many of those rsync servers in the gentoo web site. No luck.
Maybe my system is broken. I even tried the uk rsync. Don't know where

gentoo on. I am looking for a desktop replacement, therefore a
powerful yet very portable machine would be ideal.

Thanks,

[gentoo-user] xorg-server-1.6: Window Maker received signal 6

[Valmor de Almeida]

Hello,

I recently upgraded to xorg-server-1.6.3.901-r2 (gcc-4.3.4); followed all
info on gentoo web site. Window Maker does not start; it pops up an error
window: Window Maker received signal 6. I "think" the X server is running
okay. I have re emerged windowmaker-0.92.0-r7 but the problem persists.

Next I tried to start windowmaker with a default GNUstep/ and it works. I am
wondering whether there is a fix for this without having to rebuild my
customization into the GNUstep/ files.

Thanks for inputs.

No I only use a window manager (windowmaker); ultraportable laptop. The
result from glxgears used to be twice as much what is posted above when
I had xorg-server-1.5.

I use xrandr and do have an xorg.conf; some info I used in the past


http://www.thinkwiki.org/wiki/Xorg_RandR_1.2

Typically I use my laptop on a port replicator attached to a VGA.

I use windowmaker; after a switch from laptop monitor to vga or
vice-versa, I need to restart wm; all through the command-line.

[gentoo-user] need sound to listen to a adobe flash video

Hello,

I would appreciate some guidance in getting sound working such that I
can listen to an adobe flash video. I am using firefox (have the adobe
flash plugin installed which plays video but no sound) and a pretty
updated gentoo laptop.

Thanks in advance.

I think I am getting close. My video player is vlc and I reemerged with

downloaded a flv video and played; no sound. But got some clue.

[gentoo-user] problem with install-x86-minimal-20091103

[Valmor de Almeida]

Hello,

I just burned the install-x86-minimal-20091103 iso on a cd and tried to boot
a relatively old machine with it.

Here is where it stops

>> Mounting the squashfs filesystem
mount: mounting /dev/loop0 on /newroot/mnt/livecd failed: Invalid argument
!! Failed to $1; failing back to the shell...

Also, somewhere at the top of the screen output during the boot process it
says this is a LiveCD? I am confused here. Wasn't the minimal iso not Live
in the past?

Thanks for inputs.

[gentoo-user] is ddrescue this slow?

[Valmor de Almeida]

Hello,

I am trying to recover data from a failed drive. An initial attempt with dd
took over 12 hours and it was not even at half of the 80GB damaged drive; so
I quit. Info on the web pointed me to ddrescue

ddrescue -n /dev/sda /dev/sdc rescued.log

which has taken over 6 hours so far

Press Ctrl-C to interrupt

   opos:58660 MB, time from last successful read:   0 s
Copying non-tried blocks...

The "current rate" varies and sometimes is down to a few B/s!
Is this normal? The drive copied to is a USB external drive.

It's about 10 hours now since it started and here it is

Press Ctrl-C to interrupt

Sometimes the "current rate" reads 0 B/s for a long time... and "time from
last successful read" can be 8m.

Would any one know whether this is normal?

Indeed I am using GNU ddrescue and the -n flag is supposed to expedite the
recovery of data as posted in
http://www.cgsecurity.org/wiki/Damaged_Hard_Disk

"The best solution - both faster and more efficient - seems to be Antonio
Diaz's 'ddrescue' (ddrescue <http://savannah.gnu.org/projects/ddrescue/>)"

# first, grab most of the error-free areas in a hurry:
./ddrescue -n /dev/old_disk /dev/new_disk rescued.log
# then try to recover as much of the dicy areas as possible:
./ddrescue -r 1 /dev/old_disk /dev/new_disk rescued.log

The first step above finished; don't know how long it took but it was a long
time (maybe 20 hours or more?) and the screen output was

Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued: 0 B,  errsize:   0 B,  errors:   0
Current status
rescued:58811 MB,  errsize:  48909 kB,  current rate:   83 B/s
   ipos:58860 MB,   errors:  95,average rate:1365 kB/s
   opos:58860 MB, time from last successful read:   0 s
Copying non-tried blocks...
ddrescue: write error: Input/output error


Comparing with the screen output at the time of my first post,

Current status rescued went from 58656 MB to 58811 MB, errsize went from
4408 kB to 48909 kB.

Don't know how the write error: Input/output error message affect the data
in the new drive copied to. Not sure whether I should do the next step with
option -r 1.

This failed drive is still bootable and the corruption is in the partitions
/var (which I do not care) and /home; these cannot be mounted. I would like
to attempt to get a couple of files from /home that were not in the most
recent backup. Maybe I should try to rescue only the partition /home.
However this partition is under LVM. Specifically, /dev/sda4 is a linux LVM
partition. The volume group is vfda and the logical volume of interest is
/dev/vfda/home which has reiserfs file system. Is it possible to rescue data
only from this partition when under LVM?

Comment. Another reason I moved away from dd (apart from the slow running
time) to ddrescue was because of this note related to LVM.

http://www.inference.phy.cam.ac.uk/saw27/notes/backup-hard-disk-partitions.html
"Steve Holmes reports that dd with conv=sync,noerror doesn't correctly image
disks with LVM2 Logical Volumes. I haven't investigated this. He also points

peopleseem
to suggest it's generally superior to dd_rescue."

The partition I would like to get data from is under LVM (previous post).

Below is my last post copied and pasted into gmail without the html hot

Don't know how to make it plain ascii otherwise. Hopefully just eliminating
the html links will work. Stroller, is this what you are referring to?

I share all of your comments. Yes I was/am stuck inside

Therefore I am not knowledgeable of the web gmail application; I
seldom log into my gmail account with a web browser. Your next e-mail
pointed me to the "plain" option; thanks! Don't know how I could have
missed it. Originally I had looked at the settings of my gmail account

Yes.
I am afraid the text below will be confusing but will send anyway.
Will be happy to send clarifications if needed. This is a resend (in

partition on the broken drive.

Indeed I am using GNU ddrescue and the -n flag is supposed to expedite
the recovery of data as posted in
http://www.cgsecurity.org/wiki/Damaged_Hard_Disk

"The best solution - both faster and more efficient - seems to be
Antonio Diaz's 'ddrescue' (ddrescue)"

# first, grab most of the error-free areas in a hurry:
./ddrescue -n /dev/old_disk /dev/new_disk rescued.log
# then try to recover as much of the dicy areas as possible:
./ddrescue -r 1 /dev/old_disk /dev/new_disk rescued.log

The first step above finished; don't know how long it took but it was
a long time (maybe 20 hours or more?) and the screen output was


Press Ctrl-C to interrupt

   opos:58860 MB, time from last successful read:   0 s

Comparing with the screen output at the time of my first post,

Current status rescued went from 58656 MB to 58811 MB, errsize went
from 4408 kB to 48909 kB.

Don't know how the write error: Input/output error message affect the
data in the new drive copied to. Not sure whether I should do the next
step with option -r 1.

This failed drive is still bootable and the corruption is in the
partitions /var (which I do not care) and /home; these cannot be
mounted. I would like to attempt to get a couple of files from /home
that were not in the most recent backup. Maybe I should try to rescue
only the partition /home. However this partition is under LVM.
Specifically, /dev/sda4 is a linux LVM partition. The volume group is
vfda and the logical volume of interest is /dev/vfda/home which has
reiserfs file system. Is it possible to rescue data only from this
partition when under LVM?

Stroller, you mean your rescue.log showed no problematic entries? I
got over 400 lines in my rescue.log file.

I did try and thought I would post here some final info just for the

  r...@sysresccd /root % ddrescue -r 1 /dev/sda /dev/sdc rescued.log

which took ~50 hours to finish with the message:

Again the same error message. I did not care about it and moved forward
to mount the /dev/sdc drive. Enabled the LVM volume groups with vgchange
-a y (all this under the systemrescuecd boot), mounted the partition of
interest under LVM control and did a

  reiserfsck --check  /dev/myvg/mylv

It ended with

 1 found corruptions can be fixed only when running with --rebuild-tree
 ###
 reiserfsck finished at Fri Jan 15 11:46:23 2010
 ###

The next step was then

  reiserfsck --rebuild-tree --logfile rebuild.log /dev/myvg/mylv

I was then able to mount the partition and inspect the newly created
lost+found/ directory. Surprisingly I was able to find the file I was
looking for!!

It was the first time I tried this kind of HDD forensics and was
surprised with the time that it took to recover data from a relative low
storage drive: 80GB. The rebuild.log file had over 8000 lines.

Stroller, thanks for all your comments and suggestions. Yes having extra
disk space is a must to be able to recover data.

[gentoo-user] usb to ps2 adapter not working for left handed mouse

[Valmor de Almeida]

Hello,

I am just trying to understand why my usb mouse does not work properly
when connected via a usb to ps2 adapter. I have in

 /etc/hal/fdi/policy/10-x11-input.fdi

the following section


  mouse
  
  4 5 6
7
  3 2
1
  
evdev
  


which sets up a left-handed mouse. It works when the usb mouse is
plugged into the usb port but not when plugged into the ps2 port via the
adapter. The wheel works but the left and right buttons work in the
right handed mode.

Thanks for insights.

[gentoo-user] cannot open root device "sda3"

[Valmor de Almeida]

Hello,

I am trying to boot gentoo from an external USB HDD.  I am getting the
error message:

  VFS: Cannot open root device "sda3" or unknown-block(2,0)
  Please append a correct "root=" boot option; here are the available
partitions:
  Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

I am assuming that the device will be named /dev/sda since there is no
other HDD on the system. The message above does not list any available
partitions.
Any thoughts?

Here is the info from fdisk on this drive (it is a new 4096-byte sector drive):

I am experimenting with it. I could not find config instructions for
gentoo therefore I am following

http://wiki.archlinux.org/index.php/X2go

Is this sufficient?
Does fuse need to be a module or can it be built into the kernel? I am
follwing the latter.

[gentoo-user] waiting for uevents...

[Valmor de Almeida]

Hello,

Recently I bumped up (really) the number of HDD on a relatively old
system (PATA IDE's) and I noticed that it took a while for gentoo to
boot. After several weeks running, I tried to reboot and here is where
I have a problem:

 *Populating /dev/ with existing devices through uevents...
 *Waiting for uevents to be processed...
[34.7540621] Disabling IRQ #48

It just sits there for a very long time.

Any inputs appreciated. Thanks.

I had a drive that had not been used yet and had no partitions or file
system on it. I booted the machine from a gentoo LiveCD (with no
problem; weird), made a partition and created a fs then rebooted and
all worked. Don't know why I was able to boot from a LiveCD in the
first place; maybe my kernel still need some fine tuning.

Thanks.

Here are the steps I followed to configure and test the server.

1) emerge x2goserver  (needed to rebuild the kernel with FUSE)
2) following message from emerge of postgresql-8.1.11 did:
   emerge --config =postgresql-8.1.11
3)  /etc/init.d/postgresql start
4) visudo and added
users ALL=(ALL) NOPASSWD: /usr/bin/x2gopgwrapper
5) run script to create database
 cd /usr/share/x2go/script
 ./x2gocreatebase.sh

There is a "%" missing at the beginning of the line above.

[gentoo-user] liveusb not working

[Valmor de Almeida]

Hello,

I followed all the steps in

http://www.gentoo.org/doc/en/liveusb.xml

and created a liveusb on a memory stick; instead of the image 
livecd-i686-installer-2007.0.iso, I used the more recent 2008. When 
trying to boot from the liveusb I get: No operating system found. Do I 
have to use 2007? are there other steps needed to be taken? Thought I 
would ask before trying the directions again.

[gentoo-user] intelfb usage in grub

[Valmor de Almeida]

Hello,

I've been trying the following grub.conf boot

kernel /boot/vmlinuz root=/dev/sda3 video=intelfb,mode=1280x768...@60

but no luck (that is I get the 80x25 console). The only working format 
appears to be


kernel /boot/vmlinuz root=/dev/sda3 vga=xxx

where xxx does not accommodate the mode above. In fact nothing will work 
unless I use vga="something"; and that appears to be sufficient.


Am I using the incorrect video=... syntax?

This is the hint: intelfb can't change the video mode. But intelfb can

Am I understanding this correctly? vga=0x318 means 1024x768...@60. Your

depth instead of 24. Is this the only change intelfb will make to the 
video mode? or you end up with 1024x768...@60 anyway?


It seems that the mode option of intelfb does not do anything and the 
mode needs to be set with vga which has specific values.

the same one.


I am just using

Only if you don't want to use it: this parameter is necessary to

I tried both:

Yeah. It is my feeling too that pam may be a problem. I've been

I looked closely at the .bashrc (used echo "made to here" marks to

sourcing a script from a third-party package that went bad after the OS 
update. Luckily this was not in all accounts and specially not in the

After getting rid of that line in the users .bashrc all returned to normal.


One more thing to do was to uncomment the line

PrintMotd no
PrintLastLog no

in /etc/sshd_config  to avoid the double motd/last log messages upon

[gentoo-user] mouse button mapping with evdev+hal+xorg-1.5.3

[Valmor de Almeida]

Hello,

After an evdev+hal+xorg-1.5.3 upgrade, I suppose I don't need a input
device section for a mouse in my xorg.conf. (I do need xorg.conf so I
can get an external monitor working with my laptop correctly). However I
would like to reverse the order of the buttons and this old xorg.conf
section does not do it:

Section "InputDevice"
Identifier  "Mouse0"
Driver  "mouse"
Option  "Protocol" "auto"
Option  "Device" "/dev/input/mice"
Option  "ZAxisMapping" "4 5 6 7"
Option  "ButtonMapping" "3 2 1"
EndSection

My driver now is evdev but how about the device driver line? still
/dev/.../mice? or something else out of the lshal output?

  info.product = 'Microsoft Basic Optical Mouse'  (string)
  info.subsystem = 'input'  (string)
  info.udi =
'/org/freedesktop/Hal/devices/usb_device_45e_83_noserial_if0_logicaldev_input'

Okay. If I do

 Driver "evdev"
 Option "Device" "/dev/input/event7"

it works. However the touchpad which is event9 does not reverse buttons
(as expected). Do I need to configure a second input device and point it
to the appropriate event? Is this the right way of configuring
evdev/xorg through hal?

This partially solved the problem. The optical mice were correctly
configured but the quick pointing device on the laptop keyboard was not.
That is the left/right buttons were not switched. HAL does list (below)
the device in two entries that contain the input.mouse keyword.

I find it difficult to get info on configuring HAL devices on the web;
do I need to join a mailing list? It would be helpful to find some
examples of the naming of the fdi files their contents that go under the
/etc/hal/*/policy/ directory.

Thanks for the help and any other additional inputs.

I had similar problem in the past when the livecd would boot on hda but
once I booted into the new kernel I had to set fstab to sda.

As far as saving the messages during boot, there is a kernel parameter
that allows for scrolling the messages but only after the hd is mounted.
This is too late for checking kernel panic messages for example.

[gentoo-user] xterm fonts not loaded

[Valmor de Almeida]

Hello,

After an update to xorg-1.5.3 (with hal), following the gentoo xorg 1.5
update guide doc, I get warnings when launching a simple xterm. Also
when trying to change the font size (ctrl+left_mouse_button) I get
additional warnings and no font change. Do I need to emerge font packages?

Thanks,

[gentoo-user] how to move overlays to a new storage location

[Valmor de Almeida]

Hello,

A recent update of layman changed the storage variable in
/etc/layman/layman.cfg to

storage   : /usr/local/portage/layman

It was previously /usr/portage/local/layman. As a result I would like to
 move things to the new location. I actually like it better under
/usr/local/portage.

Is this just a matter of manually fixing the content of the files:

/etc/makec.conf and /usr/portage/local/layman/make.conf

to reflect the change and moving the directory /usr/portage/local/ to
/usr/local/portage/ ?

I just noticed that I do get the same messages when I run

glxinfo and glxgears

In fact glxgears seems quite slow:

-> glxgears
get fences failed: -1
param: 6, val: 0

300 frames in 5.0 seconds = 59.565 FPS
298 frames in 5.0 seconds = 59.524 FPS
299 frames in 5.0 seconds = 59.737 FPS
300 frames in 5.0 seconds = 59.884 FPS


Also I finally can reproduce a strange thing that I see when I run
ooimpress, namely as the mouse pointer moves from the original window
where the application was run to another window, a portion of the
original window is highlighted as if it were selected for copy? Not sure
I am doing a good job at describing it. For instance the frames info I
listed above cannot be seen on the window once I move the mouse pointer
out of it because the entire window is highlighted; in my case with
yellow color. Then I kill glxgears and scroll the xterm up and down to
see the frames output from glxgears; always ~60 FPS. Shouldn't I be
getting a lot more?

I wonder whether I should reemerge mesa?

remove it from world? Just edit the world file by removing the

Same here the upgrade to xorg-server-1.5.x introduced lots of surprises.
  There were too many changes for me: upgrade of gcc to 4.3.2, and
configuration of hal (a difficult thing to do on a laptop at the
moment). What really slowed me down was that for some unknown reason my
windowmaker was completely messed up and took me almost a day to get it
fixed.

Back to the glxgears problem. This is critical for me since my ooimpress
presentations have embedded animated gifs and they play really really
slow under slideshow after the xorg upgrade. A random run of glxgears
gave me this clue (go figure; I must have ran glxgears a hundred times
before I saw this message)

-> glxgears
get fences failed: -1
param: 6, val: 0
298 frames in 5.0 seconds = 59.518 FPS
297 frames in 5.0 seconds = 59.293 FPS
297 frames in 5.0 seconds = 59.281 FPS
do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter.


Googling vblank_mode on the web I came across this web site


http://en.gentoo-wiki.com/wiki/Intel_GMA

which is pertinent to my hardware and kernel/drivers. Therefore if I do


-> vblank_mode=0 glxgears
ATTENTION: default value of option vblank_mode overridden by environment.
get fences failed: -1
param: 6, val: 0
4418 frames in 5.0 seconds = 883.510 FPS
4490 frames in 5.0 seconds = 897.871 FPS
4491 frames in 5.0 seconds = 898.054 FPS
4481 frames in 5.0 seconds = 896.043 FPS
4382 frames in 5.0 seconds = 876.251 FPS

I get much better performance as I used to have before the xorg upgrade.
This is where I am now trying to gather  information on how to deal with
dri and vblank_mode settings.

Hope this helps.

[gentoo-user] coretemp and smartbatt drivers for lm_sensors

[Valmor de Almeida]

Hello,

I am trying to configure lm_sensors and sensors-detect identified these 
two modules I don't know how to build.


smartbatt

coretemp

I tried many config options when rebuilding the kernel 2.6.27.12 
(vanilla-sources) but no luck in building the modules. Looking in the 
kernel sources doc I can see the coretemp module but can't find the 
corresponding config parameter in menuconfig. As for smartbatt, this is 
what is available in the source tree:



./drivers/acpi/.battery.o.cmd
./drivers/acpi/battery.c
./drivers/acpi/battery.o
./drivers/power/ds2760_battery.c
./drivers/power/palmtx_battery.c

Re: [gentoo-user] coretemp and smartbatt drivers for lm_sensors

Also, if you are new to lm_sensors, beware that sensors-detect only
works on a subset of the supported sensor chipsets. On my computer,
for example, it detected the wrong chipsets which "sort of" worked
(gave wrong/incomplete readings). I had to manually tell it which
sensor chipset my motherboard uses.




Okay. I got i2c_i801.ko and coretemp.ko created and loaded in the 
kernel. The CONFIG_ACPI_SBS=m parameter creates two modules: sbs.ko and 
sbshc.ko; modprobe sbs loades both; hence no smartbatt. The relevant 
section from sensors-detect output is


Next adapter: SMBus I801 adapter at 18a0 (i2c-0)
Do you want to scan it? (YES/no/selectively): YES

and it calls for smartbatt. Instead I loaded sbs.ko. The current output 
of sensors is


-> sensors
coretemp-isa-
Adapter: ISA adapter
Core 0:  +56°C  (high =  +100°C)

Should the output show also info on the battery? Am I still missing 
something configuring ls_sensors?
