I installed some dbg related packages: xserver-xorg-core-dbg, libgl1-mesa-dri-dbg, libgl1-mesa-glx-dbg, xserver-xorg-video-radeon-dbg. However, I have never debugged a program like X before. So I had to learn it first. Basically I have followed http://wiki.debian.org/XStrikeForce/XserverDebugging http://wiki.x.org/wiki/Development/Documentation/ServerDebugging http://www.akadia.com/services/ora_enable_core.html http://x.debian.net/howto/use-gdb.html Since I dont't have a second machine, I chose let the bug occur and get the backtrace from the generated core file. However, I couldn't find the /etc/X11/core file because it is not being generated. But finally I found something in /var/lib/gdm3/core. The backtrace is attached to this message. > Your card is "1002:9712:103c:3642 ATI Technologies Inc M880G [Mobility > Radeon HD 4200]". > There are also some drm messages in your kern.log: > [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 1sec aborting > [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E702 > (len 537, WS 0, PS 4) @ 0xE743 > Do these appear when running gleidoscope? No, they don't. They occur when I wake up my laptop from suspension. Renato
