I just upgraded to 11.2.  I'm getting errors like this in the log:

[ 5383.723240] nouveau 0000:09:00.0: fifo: read fault at 0000011000

[ 5413.722853] nouveau 0000:09:00.0: systemd-logind[30778]: failed to

and the display output in general is unreliable enough that I'm having
trouble telling whether the performance is remotely reasonable.
