[Nouveau] Problems with nouveau driver in Ubuntu 18.04

[Ilia Mirkin]

Can you try to figure out what was updated in the latest updates? My
guess would be that it's actually the software used to display your
desktop/etc which changed.

You can disable all accel by booting with nouveau.noaccel=1.

Cheers,
