Public bug reported:
Note that this issue is reproducible on two computers, both running a
fresh install from Xubuntu 16.10. Also, everything was running fine on
both computers until recently. Also, running the Nouveau driver works.
When installing any recent version of the nvidia driver (I tried with
the 367 and 375 from vanilla repos, then the 375 and 378 from the
graphics-driver PPA), I cannot get lightdm to start if `prime-select
nvidia` is issued and rebooted. The screen is black with an artifact of
a cursor on the top left screen (But it's not blinking, I think it's
just a video frame being displayed and not updated at all).
I experimented using various settings, and also installed bumblebee to
diagnose. I got the nvidia GPU to work in some circumstances using
`primusrun` and `optirun` so I know the card function on both computers.
I'm not sure what to include in this bug report, the logs are rare and
don't show very much information.
A bit of interesting fact, is that since the problem is showing the regular
XFCE compositor has VSync correctly on the intel card (Is it related?).
Another interesting fact, is that since the problem is showing, having
compton's `glx-no-rebind-pixmap` set to true makes menus not appear in
chromium-based applications (Is it related?).
Also, but I'm not sure: it might be since I've switched to UEFI boots.
Not sure what else to include in this report, please advise.
