Comment 21 for bug 1669374

My system is using a nvidia nv117 (maxwell) card (gtx750)
With the latest updated gnome-shell 3.23.91-ubuntu2 :
- the boot process now slow down when hitting 'starting lxc container ...' then utmp, and stop there.
- hitting 'enter' show directly the text login (like tty do)
- startx seems working in the first step: see a flashing nvidia logo, but then get a blackscreen

I've purged *lxc* & libertine*, then ran autoremove and reboot : still get the same boot issue.
Get the same trouble with 'nouveau' or selecting 4.10 or 4.8 kernels.

If the actual upgrade ends with a critical booting process (even dont get lightdm login now), the problem has started when gnome-session have swicthed from 3.22 to 3.23 : the login process was apparently fine at first glance, but always return back to the login screen after 10 or 20 seconds (suggesting a kind of race), then the opened gnome-shell session was stable. Neither journalctl nor logs have logged something usefull about that sadly.
