Bug#840433: gnome-shell: barfs on Nouveau X.org

[Martin-Éric Racine]

Package: gnome-shell
Version: 3.22.0-1+b1
Severity: important

I get this since upgrading from GNOME 3.14 (stable) to 3.20 (testing).  Tried removing xserver-xorg-vidoe-nouveau and let X use xserver's built-in modeline driver, but it doesn't solve it.  Basically, GNOME 3.20 freezes at random for several minutes at a time.
