Public bug reported:
With a live USB stick or a freshly installed version of 18.04, gnome-
shell crashes at startup. I get this error in dmesg:
gnome-shell[xxxx]: segfault at xx ip xx sp xx error 4 in
nouveau_dri.so[xxxx]
The computer is a MacBook Pro with a GeForce 320M GPU. Using the
proprietary driver listed in the "additional drivers" tab doesn't work
either (I get a black screen at startup with no access to a virtual
terminal).
Everything was fine on 16.04, with nouveau or nvidia drivers.
The only workaround is to blacklist the nouveau driver. I have of course
very poor performance then.
