I attach Xorg.0.log with the crash, please tell me what packages do you usually want compiled with debugging symbols to get proper backtraces apart of intel driver. This is a regression over 2.17.0-r3, it also crashes in the same way with mesa-8.0.1-r2 or stable mesa Thanks Reproducible: Always Portage 2.1.10.51 (default/linux/amd64/10.0/desktop/gnome, gcc-4.4.6,

Created attachment 306831 [details] xorg.conf
Created attachment 306833 [details] Xorg.0.log
If no DRI is involved, having xf86-video-intel and xorg-server built with debug symbols is usually enough to get a meaningful backtrace. Also check whether that happens with sna disabled too.
Created attachment 306877 [details] Xorg.0.log Updated log after recompiling with debugging info (but the log looks to catch the same useless info :S, should I start X directly from gdb then? What is the easiest way to do that for X?)
Looks like disabling "sna" makes crashes to go away
http://www.x.org/wiki/Development/Documentation/ServerDebugging has some instructions for attaching gdb to the X server (it is recommended to use ssh). If you have a core dump, you can also load it in gdb and it should show the debug symbols.

As I only have a machine now to get this I have tried to get a core without success: # ulimit -c unlimited # /etc/init.d/xdm restart -> make it crash, I am unable to find the core, should it be present on the same dir I launched X? (years have passed for me without using core files :S)
Created attachment 306889 [details] backtrace.log Finally got it but it's still useless (even if I have xorg-server with debugging symbols)
Created attachment 306891 [details] core.xz This is the core file
The backtrace from attachment 306889 [details] looks different from the one in attachment 306877 [details]. They are probably unrelated crashes.
(In reply to comment #10) > The backtrace from attachment 306889 [details] looks different from the one > in attachment 306877 [details]. They are probably unrelated crashes. But both were got opening pdf files (and only in that cases, also 100% reproducible in my case -> open pdf files -> X crashes)
One crash is in glx code, the other is in ddx. Try to get a stack trace with symbols for the ddx (intel_drv.so) crash. For the other one I am not sure why the libglx.so debug symbols are not displayed.
I have debugging symbols for: x11-drivers/xf86-video-intel x11-base/xorg-server
I am trying to get cores today but I am unable to find them :S, where should they be dropped? I have done the following: 1. Edit xorg.conf to put: Section "ServerFlags" Option "NoTrapSignals" EndSection 2. Run "ulimit -c unlimited" 3. /etc/init.d/xdm restart -> Reproduce the crash, but nothing in /root :(
This looks fixed in 2.19.0 :D The problem is that I finally was unable to get a proper backtrace :( (then, if problem reappears... :S)
