Title:
Xorg crash prevents login
Status in xorg package in Ubuntu:
New
Bug description:
After a recent update, it's no more possible to log in to Ubuntu 16.04
when using lightdm to access to Unity.
If I try to login lightdm disappears as if it was loading Unity, but
after a few seconds the login prompt appears again.
### Workaround ###
Current workaround has been to purge all nvidia drivers, as nvidia-352
was installed.
The same driver (nvidia-352) works correctly in trusty, and until recently it
used to work even on xenial.
