x has been crashing at random with kwin+compositing since i updated to current (the major X updates, nov 14). everytime it does i get this message:

[drm] Num pipes: 1
[drm] Setting GART location based on new memory map
[drm] Loading R500 Microcode
[drm] Num pipes: 1
[drm] writeback test succeeded in 1 usecs

seems that the gpu resets itself. only solutions that work right now is either turning off compositing or using kms.

i've tried recompiling libdrm/mesa/xorg-video-ati, using a fresh .kde folder, mesa 7.8.1/7.8.2 and the problem still persists. am running out of ideas and wondering if anyone else is having the same issues..

thanks

If you roll back, does the problem persist?

is there a way or feature to roll back to certain dates? or do i have to roll back on each package individually?

The output you posted is completely normal. It happens when you switch between X and the console. Have you taken a look in your /var/log/Xorg.0.log file to see what it says about the crashes?

i thought that the messages were normal before this, but that's the only logs i can trace everytime kde crashes back to the login screen. kde starts up fine and Xorg.0.log looks normal but i'll have a look again at the next crash.

Try this:
and please give us a feedback.

HTH,

i typed in the command but there wasn't any output. i'm not familiar with the sed command but i understand that changes the 'OpenGLIsUnsafe=false' to true right? KDE had changed the config to 'true' before and i had to manually change it to 'false' to enable desktop effects, otherwise it won't allow the effects to be enabled. i've never had any issues with this particular configuration before this.

Right. sed doesn't output anything but in case of an error (and in you case the command did nothing as you already had 'OpenGLIsUnsafe=true')
What puzzles me is that here (Slackware-current as well) if I remove ~/.kde and then launch KDE I find 'OpenGLIsUnsafe=false' in kwinrc
I have a nVidia GPU, not an Ati one , could that be the cause of this different KDE's behavior ???

In my case KDE crashes at startup with either 'nv' or 'vesa' X drivers, it only startx correctly with the 'nouveau' X driver, unless I set 'OpenGLIsUnsafe=true'. But again, I have a nVidia GPU.

I don't see anything wrong here. Are you sure these data were output after the crash, not at X startup ? ...May be you have something interesting in /var/log/messages or /var/log/syslog ?

i think it looks fine because x crashes back to the login screen..i'll change to init 3 and post another logfile

Perhaps it's not X that is crashing, but KDE itself. Check ~/.xsession-errors

Adam

started kde in init 3 and reproduced the crash..this copy of Xorg.0.log contains the errors.

Perhaps try enabling KMS.

Adam

i can confirm that enabling KMS solves the problem. only reason i'm hesitant to use KMS is because of some flickering issues. i was wondering if the problem lies in xorg 1.9.2 and if it's safe to revert to the 1.7.7
