Hi Ilia,

yes - I installed it, but the line:
"unw_get_proc_name failed: no unwind info found"
was still there, so I compiled nouveau myself and installed with debug symbols
but it doesn't help to full unwind, so finally I compiled whole xorg+debug
symbols and complete unwind still doesn't happen.
Isn't it that this unwind is for some libc calls which is irrelevant?
I am attaching new backtrace from console output.

No, it is not failing with nouveau alone (and commented radeon driver).

I was also trying to disable xinerama (with radeon+nouveau) - then it is also
not failing. It seems this is triggering only with enabled xinerama and both
radeon and nouveau drivers loaded.
