--- Comment #70 from Michel Dänzer michel@daenzer.net --- (In reply to tempel.julian from comment #68)

I did it, but it stopped after hitting the two breakpoints the first time without me having moved the mouse at all. I suppose this isn't enough? Would it be possible to provide me with a short hint how to let it run longer?

Enter "continue" (or just "c") at the gdb prompt to continue, and wait for a few breakpoint hits, to see if they're getting hit from multiple places.

Also, make sure debugging symbols are available for /usr/lib/xorg/modules/drivers/amdgpu_drv.so (and ideally also for Xorg and its modules), otherwise the backtraces are useless.
