KDE 4.5.2 Random Logouts... Bug?

[jgehrig]

Just upgraded my desktop with a new motherboard and CPU, since I was upgrading from x86 to amd64 I did a clean install of gentoo on my root partition... everything went well except my install of the latest version of KDE (4.5.2 ~amd64). Currently I get random logouts, some are predictable and some are not. For example I can get my system to logout anytime I click the cashew thing and mouse-over some of the buttons in the menu that pops up. Other times I am using an application and it unexpectedly returns to kdm... I'd attach some logs for one of these logouts but I don't know what to include... I've googled around and can't find anything similar...

(When I say logout its more of an abrupt return to KDM)

I'm currently running XFCE and it's working fine, but I'd rather run KDE...

Anyone have any ideas? Is there a log I could look in for some more info?

To me, it seems like the X server is crashing. If you kill X forcibly, you will return to kdm abruptly. If KWin or Plasma crash, they will typically restart themselves and your session will stay active. It's probably something in Plasma triggering a bug in the X server or a display driver.

Therefore, I'd check /var/log/Xorg.0.log and see if there is some explanation for the crashes.

make.conf could also be interesting. Are you using any experimental flags? The raster flag for Qt used to crash some KDE apps if made default, for example.

What video driver are you using?

You can try to turn off desktop effects to see if it will still happen. But first check your logs after crash like pingufunkybeat suggested.

I'm on 4.5.2 since it appeared in portage with no problem.

As far as I know there are some problems with intel cards/mesa...

There are/were problems with most mesa drivers, but intel seems to be the most affected. Radeon cards had problems with effects, but this has been fixed in mesa git.

Anyway, the crashes should typically kill kwin, not X. We won't know what's going wrong without looking at the logs.

Another file you could check is /home/username/.xsession-errors.

I got the same problem,I don't know why... When I click the job rest in the panel...KDE broke down unexpectedly and back to kdm. How to deal with this ?

I'm now reinstall gentoo with KDE. I wonder if this appears again.

Please post the regular stuff when having driver problems:

cat /var/log/Xorg.0.log
glxinfo |grep enGL
dmesg |grep drm
emerge -pv libdrm mesa xorg-server
kernel config

Which chipset? Which KDE version? Which kernel?

Hi, if you consider this an old thread, sorry for bumping

But I'm still having this issue so I'll do my best to provide information (please bare with the newbie):
-----
duke@dukenet ~ $ grep EE /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

[ 4514.944] (EE) Failed to load module "fbdev" (module does not exist, 0)

(I don't think that is related as I'm using the radeon driver and uvesafb for framebuffer).
-----
glxinfo is a no go as I don't have it installed (do I need to install mesa tools or something?)

Hi

I also have this problem since I upgraded my desktop's Gentoo last month. I found on this forum another person having our issue, "sudden log-out of desktop...". In my case it also happens when switching to another app / window using the task bar buttons, or when Firefox tries automatically complete an URL when typing, etc...

I am currently on my laptop thus I cannot provide config file but will proceed soon when back at home.
Nevertheless I already looked at /var/log/Xorg.0.log an neither crash norerror nor warning is reported in there after these "logouts".

I have been looking a lot for solutions on the forum, no solution found, so ... I am very interested by any progress !

Regards

PS: This is not the first time that all works well before emerge --sync and emerge -u world, and then after ... kde is messed up !
When will kde become managed ? Maybe too heavy and complex now ... Maybe is it not upgradable, just (re-)installable from scratch due to so frequent deep heavy changes.
