From the log, the problem appears to be in pixman or in xf86-video-intel. What versions, and with what USE flags, of the following packages do you have installed? x11-libs/pixman, x11-drivers/xf86-video-intel, media-libs/mesa, x11-base/xorg-server, gnome-base/gdm. x11-libs/pixman-0.26.0 media-libs/mesa-8.0.4-r1 gnome-base/gdm-2.20.11-r1 x11-base/xorg-server-1.12.2 x11-drivers/xf86-video-intel-2.19.0 -O2 -march=i686 -pipe Does the crash happen both with SNA and UXA? And can you try pixman/xf86-video-intel from ~arch? Excuse me, I'm relatively noob, what should I do about SNA and UXA? And I suppose by "~arch" you meant "~x86"? Yes, ~arch is a general term for ~amd64, ~x86 and so on. According to your Xorg.0.log you are using SNA now. Set the AccelMethod option in the Device section of your xorg configuration to change this. See "man intel" for details. Note that if you update to xf86-video-intel from ~arch and want to use UXA as the AccelMethod, you will need to re-emerge xf86-video-intel with the "uxa" USE flag enabled. Though I didn't have SNA in AccelMethod, I re-emerged xf86-video-intel and pixman with "-sna" flag and so far autologin worked for 2 reboots. Before stating that the issue is solved, would you let me perform some more testing? SNA is the new default for intel, and UXA will go away in the future. So the issue is cannot be considered solved either way. Well, it seems the re-emerge of pixman really helped, the problem is gone, but there's one question, I really want to use SNA, so how to get rid of the problem with it?

Reporting it to upstream (with tracebacks, logs) usually helps. Just one example: https://bugs.freedesktop.org/show_bug.cgi?id=55823 Are you still having troubles with the latest ~arch ebuild (2.20.14 as of today) with *both* USE=sna and Option "AccelMethod" "sna" in your xorg.conf? If so, please let us know and open a bug report upstream [1]. Thanks [1] http://intellinuxgraphics.org/how_to_report_bug.html |
Created attachment 327338 [details] Xorg.0.log.old with errors It happens almost every time on GDM startup: the login prompt is displayed (although it should not, I have set autologin), I enter my username/password and hit "enter", then the screen goes blank, switches to tty1 and after a second or two the GDM login screen appears again, I try to login this way up to 4 times in series, but on the last attempt it logins successfully. It's VERY annoying. Re-emerging xorg-server helps, but only for the first reboot, after that the problem appears again. The Xorg.0.log file is ok, but luckily there's Xorg.0.log.old, which states that XServer segfauls. That's all I was able to investigate
