Details

kdm seems to segfault randomly since the latest update to 4.11.2-1. As a lot of gnome packages have also been updated to gnome 3.10, there might be a correlation. I attached xorg, kdm and xsession logs which display the segfault.

packages installed:
* extra/kdebase-workspace 4.11.2-1
* extra/gtk2 2.24.21-2
* extra/gtk3 3.10.0-2
* extra/intel-dri 9.2.1-1
* extra/libva-intel-driver 1.2.0-1
* extra/xf86-video-intel 2.21.15-1 (xorg-drivers xorg)
* extra/pixman 0.30.2-1


* segfault in kdm.log:

I have a coredump of a crash, but it is too big to upload here. If someone wants to take a look I can mail it or upload to an ftp server.

Nevermind, xz did the trick, coredump is now attached.

seems to be caused by a memory corruption on free by libpixman, reported here too:

According to the upstream bug report this should be fixed with a more recent intel driver pkg we now have in our repos.

Please check this. Maybe even play with SNA/UXA/(Glamor) acceleration.
Comment by David Gabriel (b2c) - Thursday, 30 January 2014, 21:27 GMT
Thanks for the hint, switching to 'uxa' solved the problem while when using 'sna' I still get crashes, even on latest drivers. So it's ok to close this bug I guess?
Comment by Laurent Carlier (lordheavy) - Thursday, 30 January 2014, 21:36 GMT
We can't close it, it's a workaround as sna is the default acceleration choice.
Comment by Andreas Radke (AndyRTR) - Saturday, 01 February 2014, 10:20 GMT
Please check 2.99.908!
Comment by David Gabriel (b2c) - Sunday, 02 February 2014, 18:21 GMT
Sorry, that latest comment was to quick, just had another crash, so the 2.99 drivers don't fixed the problem either.
