[gentoo-user] KDE4: Constant crashes in conjunction with Konsole

[Frank Steinmetzger]

[-- Attachment #1: Type: text/plain, Size: 1105 bytes --]

Hi guys,

until now I've been quite a KDE4 hater, but I'm willing to give it a try from 
time to time. So I installed 4.3 parallel to my beloved 3.5.10 and was quite 
pleased with it. However, I have repeating crashes of my entire X. Mostly it 
happens when I open Konsole, the next often occasion is opening a menu (main 
menu, context menu, you name it), but also only after a Konsole windows was 
opened. All I see is a quick error message about glibc, then X restarts and 
I'm back at kdm.

I use a laptop with a Geforce 7600 GPU, running on nvidia-drivers-180.60.
First I had 4.3.0 installed from main portage tree, but I had a faint
hope they would have fixed it by now, so I installed the live slot from
kde-testing. I already had this issue with older version.

Could anyone shed some light on this, please? One thing I can think of is to
disable 3D effects, but they're working quite well and it's the same with 
*cough* Vista - they are the main reason for switching over from a previous
version.

TIA

The 'dmesg' command and the ~/.xsession-errors and /var/log/Xorg.0.log 
files should contain the specific error messages.

X errors might actually be in /var/log/Xorg.0.log.old by then.

I had a similar problem on my laptop last time but I do not remember if 
it is a glibc problem or not. And my problem had gone after I rebuild 
the whole system using emerge -aeNv world.

Sorry for not answering earlier, but I rebuilt another kde4 version, starting 
from a clean system backup. I'm finished now and had my first test login. Of 
course, the problem is still there, but neither dmesg nor any Xorg*.log 
contains glibc.

~/.xsession-errors however was a little more informative, but only a little.
I've attached the relevant parts, but they don't tell much.

I had Konsole-related crashes and other weirdness when I first
switched to KDE4. It turned out to be related to fonts! I installed
DejaVu fonts and used them for everything in KDE's font config, and in
Konsole I'm using "Fixed [ETL]" size 10 (I'm not sure which package
that came from, but I think it's one of the core Xorg fonts).

It probably has nothing to do with your problem but I figured I would
mention it just in case.

I, too, changed the font to a bitmap variant (terminus). But that didn't help; 
though crashes occured less, if my memory serves me correctly, they were 
still there.

Which permissions do you mean in particular? It's a fresh install with a newly 
created test user acount.

I've disabled desktop effects, in case there was some clash with the 3D layer, 
but apparently it's (also) something else. Though now Konsole seems to 
cooperate, right-clicking on the context menu of the KPowersave tray icon 
leads to a crashing X with 100% certainty. I'm rebuild glibc now, see what 
happens.

That's exactly the kind of problems I was having, and went away when I
redefined all of the fonts in System Settings -> Appearance -> Fonts.
I don't think it even matters which font you change it to, just that
you change it to something. IIRC it had generic font family like "Sans
Serif" instead of specific font names. FWIW. :)

permissions of /tmp /var/tmp and the kde stuff in /usr/share.

make sure that all of your system is build with the same compiler.

I've only changed font sizes, not the families. Besides, kdelibs contained a 
gentoo patch changing the default to Dejavu, so they're all set to Dejavu 
already. I've changed them to courier new, and I got a crash, this time with 
context menu of the KDE4 notification icon (i).

And lol - now I can't even open system settings anymore. Perhaps it's 
something with font rendering. Deleting .fonts.conf, I could open system 
settings again, but still I can't open a context menu without a crash.

I get occasional crashes with various odd KDE4 apps, like:

Moving two bookmark folders around in Edit BookMarks is certain to crash.
kmail crashes while doing deleting several mails on IMAP folders in quick 
succession.
Kopete crashed regularly today while shuffling contacts around.

I agree that emerge -e world is sure to sort it out but we won't find out the 
actual cure. We have three guys at least with this problem, so I suggest a 
trick:

List the likely problematic packages (kdelibs, Qt, glibc, font stuff).
Split the list up.
When one of us hits a fix, the others can test it.
With luck...

But there, only the app crashes, as I understand. Here it brings X down as 
well. OTOH, I actually didn't have any application crashes in the short time 
I tried it out in my previous install half a week ago.

Of course. I did before I started installing kde4, and also now, which only 
revealed some missing links for kde3 apps, because I had to remove kde3's 
bluetooth packages.

I've had this issue today with a new KDE 4.3.1 installation (actually
not so new, it was running fine for 4 days). I decided to track down
what was probably causing this issue since it apparently to came from
nowhere.
Well, after testing some configurations I realized that changing fonts
size (specially menu's font) could lead to this problem, but reverting
the size didn't solved.
Them I started changing xorg.conf and found an workaround: disable
BackingStore. I've tested several times and the crash never happened
with BackingStore off. And I actually turned it on yesterday, so at
least on my system that's the cause of the crash.
So if you are experiencing this and have BackingStore on, disable it.
If you don't have BackingStore enable try changing some other
configuration in xorg.conf, it may help.

I agree with Dudu, nvidia-drivers is the likely culprit. There were huge 
problems in the early days of KDE-4, it's very possible that bugs are still 
lurking.

A useful site to trawl looking for similar problems and solutions:

http://www.nvnews.net/vbulletin/forumdisplay.php?f=14

It's a semi-official announce site for nVidia plus general Forum. The driver 
devs read the list and respond to major issues.

A great many thanks to you, I've just tried it and it seems to have the effect 
you described. I'll dig into it further. But now of course I'm trapped 
between two worlds - stay with my sceen efficient and faster 3.5, or begin a 
liason with 4.3 for the benefits it provides, but also with its latent 
lagginess. *ponder ponder*

Thanks for the link Alan, it's very useful. Actually this bug has been
reported at that forum:
http://www.google.com/cse?cx=partner-pub-6344472472167039%3Ayq78am-jukz&ie=ISO-8859-1&q=backingstore&sa=Search+Site

I was having a similar crash with gnome/metacity when I upgraded to
gnome 2.26 but I never tried to track down the bug, I just switched to
openbox, which didn't crash in gnome. But in KDE/Openbox the crash
happens, but less frequently than with KWin

Great that it worked!
One thing to notice is that BackingStore is implemented by de X
server, not by the driver, So maybe this isn't a bug in nvidia-drivers
IMHO you should use KDE4 as now it's pretty stable (without
BackingStore, no issues at all here)

Just for the archive: the problem was solved by disabling BackingStore for 
nvidia-drivers in xorg.conf. It's a common problem with nvidia, see

Emacs is a great operating system, which only lacks a good editor.
