Created attachment 212106 [details] Backtrace
Created attachment 212108 [details] Backtrace with gdb I got this running 'gdb --args X' from other machine via ssh.
Both traces are useless. The first one because there's not enough debug info, the second one because running X in gdb requires special voodoo if you want it to work. Better fix the first one : please read this guide [1] and make X crash again, you should get a better trace. You should rebuild libdrm, xorg-server and xf86-video-ati. Thanks
