Title:
lightdm crashed with SIGSEGV in g_timeout_dispatch()
Status in “lightdm” package in Ubuntu:
New
Bug description:
While running steam big picture mode main menu I started to notice
some artifacts of corruption on the other two displays when using the
wireless xbox360 controller and trying to scroll left at the end of
the menu. Then as I tried using apport-bug the display started to
lockup and blackout then the whole system locked up and this error
report was waiting upon the fresh boot and login to the user account
along with many other errors.
