Upgrade to 6.1 from 6.0 breaks X windows. I was using nouveau on an
nVidia adapter. Consoles are working so it's not a show stopper for
me. It's quite annoying, though.
The display is completely broken up. I can tell the login appears. But
the display is sectionalized into two or three pixel high and maybe 128
pixel wide chunks on a 1920x1200 LCD display (that X does not know about
- gateway FHD2401.)
