I decided to try it on a MS Surface Pro 4 on a new, clean install.

Plasma/KDE seemed ok, except hibernate would not work.  After seeing
this thread on various "problems" I installed xfce alongside KDE last
night, and logged in.  Hibernate now works fine and I am on my 4th
resume without a crash :)

bye bye KDE ...

I just installed KDE 5 in order to try how one application works on
it, and also due to my curiosity.  The applications that depend on it:
konsole and dolphin, doesn't work well if KDE5 is not itself the one
that's running.  In dolphin, some icons don't show.  konsole also
doesn't show some icons when it uses them as its own icon.  It seems
to be like a problem with rendering stuff that require some services
running.  This happened before and after I changed appearance
settings.  I even cleared cache and stuff.  Firefox seems to have been
affected by it as well.  It doesn't show the scroll bar button, and
some widget borders looked a little different.  Perhaps this is also
just about Gtk3, but I'm not sure about it since stuff work when KDE
itself is running.

KDE5 or Plasma itself seems to have gotten much more responsive and
faster compared to the last time it was in 4, but I still find XFCE4
easier to configure to appear and work the way I want a desktop
environment should.

I just downgraded konsole and dolphin for now, and also rebuilt
firefox with gtk2.

The things that are weird or don't work right.  My clock on the panel
thingy at the bottom, it winks at me, a lot.  It's annoying.  It isn't
as bad after the update a couple days tho so maybe it is being worked
on.  Also, if I put to many widgets/??? on the panel, it locks up a
lot.  Things that update a lot make it worse.  It works fairly well with
a CPU and network monitor.  If I go past that, it tends to lock up
more.  The device notifier thing, worthless except for telling you
plugged something in.   Nothing I click on does anything. 

Now to plasmashell.  It gets CPU hungry to the point I have to kill it. 
If it isn't that, it locks up completely.  Either way, I have to kill it
and then restart it, or log out and back in again.  If you run into
this, I'll be glad to share the command, maybe you can even improve it
more.  ;-)

Konqueror.  Well, I haven't been able to use it for a while and been
stuck with Dolphin.  I don't like Dolphin but it works, just not like
I'm used to with Konqueror.  What it does.  I use a folder desktop which
means I have folders and such on my desktop that I can click on to go
find a pic, video, document etc.  When I do click it with Konqueror
enabled, I get hundreds of Konqueror processes/windows.  Even after I
kill it with pkill, it pops up again and starts opening new
processes/windows.  I just have to keep killing it until it stops.  I'm
not sure what to make of that.  Oh, after you kill and restart plasma,
you can't click and open a desktop folder any more. 

I had several other oddities until I gave KDE a fresh start on configs. 
I renamed .kde4 and .config and some things did improve or just started
working correctly.  I think the .config is the most important part on
this.  There doesn't seem to be near as much in .kde4 any more.  If you
use Kmail or something, that could change things.

So, depending on your settings, you may or may not have those issues.

I run somewhat stable but I've got all of KDE and its related packages
running keyworded packages.  I'm not using the - ones but I'm right
there close to it. My core stuff, things needed for booting etc, those I
try to keep on stable.  If you want to run like mine, let me know and
I'll send you my short list keyword file, emerge's autounmask will give
you the rest based on your USE flags etc.

Oh, I use Seamonkey for my email so I have no info on things like Kmail
and such.  I see others have posted about those.

That's all I can recall at the moment.

Hope this helps.

Are you sure that the HOME envar is defined for the "nologin-user"?

Is there a existing home directory defined in /etc/passwd for this 
user?

Thanks for the solution, I moved stuff to the local overlay and now my

Of course that leads to the question... why on earth did they give a
kde4 package a dependency on a kde5 package. No wonder everything got
screwed up.

Re: [gentoo-user] Wireless DHCP takes over resolv.conf

[Marat BN]

The solution I use when dealing with the problem of network software
overwriting '/etc/resolf.conf' is to make that file immutable with
'chattr +i'.

Not quite an answer to your question on nameserver prioritization, but
could be useful to prevent your nameservers from being changed.

Oh, I'm sure there's some brain-dead ISP or BofH somewhere who blocks
traffic to outside DNS servers.  Inevitably it's done in the name of
security.

Even if 8.8.8.8 is reachable, there may be internal, locally defined
hostnames that Google won't know about.

That said, after problems with various DNS servers on various
networks, I usually default to using 8.8.8.8...

real user, real unix useraccount. we will exchange confidential news,
but the user can't use pgp. so he has a local mailaccount, so we change
news via ssl over my mailserver.
when a message arrives for the user, I will send a alert to his
aol-account.

I test the script before, but it works not on nologin-user.

With Gmail I used to (almost) never delete messages and they accumulated over

The semantic desktop with database indexing was an attempt of Linux to break 
into the MSWindows monopoly of the enterprise desktop.  The world has moved 
since, but back then EU money was invested to kick all this off.


> Anyone else have comments on using KDE 5 ? -- thanks so far.

Unlike Neil I found Plasma 5 a major climb down from KDE4 in terms of 
interface usability.  A lot of things were broken and for me still are.  For 
example Konqueror on my laptop does not integrate with Dolphin anymore, menu 
icons on Dolphin are not shown, Network places are empty, Kim4 does not show 
up in the dropdown menu, etc.  I noticed the same problems on a desktop which 
had the full Plasma5 desktop installed.

Things are gradually improving, but they are at present a rather retrograde 
attempt at improving something which was not broken.  In other words, similar 
to the KDE3 to KDE4 migration, but not as bad this time.

At least two ex-KDE4 users asked me to remove Plasma from the their desktop 
and install something different ...

I haven't fully migrated yet because I like to test this kind of thing on my
test box but it has a very old NV34 (I don't throw good hardware away)
video card and both SDDM and KF5 are useless with it. On SDDM only the user 
icons show, everything else is black. On plasma 5 most images and some UI
elements are garbled or black. So if you have old or rare video card check
that it works with a live CD before you take the plunge.

That's why I phrased my suggestion as a question. I'm honestly curious:
aren't DNS servers like Google ones (8.8.8.8 etc.) supposed to be reachable
from anywhere? If you can't reach them, isn't your connectivity inherently
broken? I'm sure I'm missing something here.

yes and yes.

So you have copies of the same script in each user's $HOME/bin? Why not
call them from a single location? Are you sure the scripts are identical?

Does the procmail log give any clues?

No. At least for me it is -O0. I tested by compiling a small program with 
different
options and diffing the binaries. You can get a definitive answer for any gcc 
option
defaults like that. As long as your test program is complex enough to use those 
features.
You can also diff the output of the -f and -fno flags and if they don't differ 
then
either the test program is not complex enough or the feature has not effect on 
your arch
or platform.

[gentoo-user] KDE 5

[Raphael MD]

As you talking about KDE 5, tell me something, nowadays is a good moment to
migrate from KDE 4?

I only use mplayer, firefox, wine and simple diary apps.

Is it a reliable choice to migrate?

it works for default user. it does not work for nologin user.

I've been a contented user of Mutt since 1998, so that's no problem.

BTW Whatever is the point of keeping  125 K  mail messages ?
-- at  1 min each , it would take  90 days  to read them (without sleep).

As for desktop indexing, it's simply an overweight tool
for those too lazy to keep their directories + files in proper order (smile).
It seems to have been invented to try to help users of proprietary systems
which make it difficult to keep track of anything for long.

Anyone else have comments on using KDE 5 ? -- thanks so far.

I've been using KDE 5 for months. There were a few glitches at first, but
it's been fine recently. I don't use KMail, I've never liked it, or any
part of KDEPIM.

Having to install some parts of Plasma does not mean you have to use it as

I don't use the full plasma desktop, but use KDEPIM and some other KDE apps 
with all their unavoidable dependencies.  It is usable for me, on two machines 
where akonadi is running on MySQL and on my laptop with PostgreSQL.

I use enlightenment as my day to day DE and Fluxbox as a fall back.

You need some CPU horsepower and patience to let akonadi index all messages in 
the database.  If your PC is resource constrained it'll have trouble managing 
large mail boxes.  I remember a Pentium Duo with 4G RAM taking overnight to 
update my mailboxes, which in their totality contained more than 125,000 
messages.

When I repeated the exercise with fewer messages (less than 5,000) the 
response was much more reasonable.  it took a few minutes, rather than hours.

I did manually mask everything, I added yours to it as well, but emerge
still wants to pull in qt5 and a bunch of stuff not needed. I've
attached the emerge output - you can see it's pulling masked packages
in. I can't figure out what wants to pull in all the qt5 stuff.

I've already manually installed the packages from kde-sunset:

# emerge -pv kde-meta

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

...but a world update wants to change everything. And I can't figure out
how to read the tree output from emerge. I've attached that too.

Oh, I also read the manpage for eshowkw and it doesn't show packages
from overlays by default. You have to use the -O switch, then it shows
it. One more thing to remember...

if I want to go on using my regular daily apps Konsole Gwenview Okular ;
yes, I know I can limit exposure to their requirements

Before I plunge into that, is anyone else using KDE 5 every day ?

http://www.funtoo.org/Keychain

Note that you, portage and root are 3 different users, so you must make
key pairs for reach on each source machine you will ssh from.

Then you need to add each of those user's public keys to each
destination user's authorized_keys file on each machine you want to ssh to.

That can be a lot of key copying :-) 3 x 3 x # of machines

Finally, on each machine you will ssh from and as each user who will do
the ssh'ing, you must run keychain at least once to store the key creds.
They should then persist until reboot, when you must run keychain again
for each user.

The idea is that a given user's keychain creds are valid over all that
user's login sessions on a machine. User's cannot share each other's
keychain

[gentoo-user] Using SSH around the LAN

[Peter Humphrey]

Hello list,

I remember some time ago reading a guide on the Web to using ssh and keychain 
to simplify routine tasks, but now I can't find it.

What I want to do is to use scp, ssh and rsync to copy files and directories 
from one local machine to another, without having to submit a password on 
every occasion. I want to be able to do this as myself, as portage or as root.

Is there a guide to setting up password-less authentication to enable me to do 
this?

Does script.sh contain a definition for a command interpreter

Hi,

gcc-5.3.0 manual says:
  The default setting (when not optimizing for size) for 32-bit
  GNU/Linux x86 and 32-bit Darwin x86 targets is
  -fomit-frame-pointer. You can configure GCC with the
  --enable-frame-pointer configure option to change the default.

So it depends not only on the arch, but also on how gcc was
compiled. Strange, but here Gentoo x86 I have -fomit-frame-pointer
disabled by default, so either gcc manpage is wrong or Gentoo
disables frame pointer during gcc configuration (I can't confirm the
latter after digging into toolchain eclass).

This flag is yummy on amd64 and very important on x86, since x86
has only 8 "general purpose" CPU registers, 4 of which have special
use, so only 4 are available for general computations and 1 of them
is wasted on frame-pointer, not nice. The cost of extra register is
that profiling is no longer possible and debugging may be mangled a
bit.

Looks like -fpic disables -fomit-frame-pointer at least for some
pieces of the code: hand-written 4-registers assembly makes -fpic
fail in some cases on x86 (e.g. ffmpeg).

Andrew Savchenko
