Bug 56503

Please attach (as opposed to paste) a Xorg log file showing a crash.

> installed debuginfo packages, but still can't get backtrace

To get a full backtrace, it's best to attach gdb from a remote login to the Xorg process. See http://wiki.x.org/wiki/Development/Documentation/ServerDebugging

Meanwhile, please attach the Xorg log file anyway.

Created attachment 69243 [details]
Xorg.log

It is old backup machine which I'm only using when main machine doesn't work.

The log file doesn't show an actual X server crash. Please describe the symptoms a bit more.

got some core dump

AFAICT those aren't crashes but input event queue overflows. Those could happen e.g. because an input device is generating more events than the X server can handle in time, or because the GPU is hanging, ... That's why I asked you to describe the symptoms of the problem more. Why do you say the X server crashes?

Xserver crashes because there is core dump.
Fast mouse motion during page loading in Chrome crashes Xserver with 100% reliability.

(In reply to comment #9)
> Xserver crashes because there is core dump.

Then please attach a backtrace from gdb and the core dump, or at least a log file showing an actual crash.
