Title:
X server crashes with SIGBUS when resuming from suspend
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
Every night I suspend my laptop and resume it in the morning. At least
once a week, the X server crashes with SIGBUS when resuming from
suspend.
I scoured systemd journals and all logs under /var/log, and this was
the only suspicious message I found:
[ 59358.134] (EE) /dev/dri/card0: failed to set DRM interface version
1.4: Permission denied
As my graphics card uses driver i915, I installed xserver-xorg-video-
intel-dbg but couldn't find any package with debugging symbols for
xserver-xorg-core, so running 'sudo gdb --core=/core' only yielded
this:
Core was generated by `/usr/lib/xorg/Xorg -core :0 -seat seat0 -auth
/var/run/lightdm/root/:0 -noliste'.
Program terminated with signal SIGBUS, Bus error.
