Xorg crash on startup

[Vasiliy Ivashin]

Ubuntu 16.04.2 LTS
Xorg 1:7.7+13ubuntu3

Occasionally upon initial login system reports that an error has occurred. It does not seem to happen every time on startup, but occurs quite often. Afterward it does not seem to affect operation and stability.

Please let me know if I can provide any other useful information for debugging (I'm a linux newbie so may require some guidance for this).
