Xorg.0.log Broken
The xf86-video-ati driver has been segfaulting on me the last few days I've git
bisected to:
# bad: [80f3d727f93cb6efedd2b39338d2301035965fe2] On screen resize, clear the
new buffer before displaying it

# first bad commit: [673e1c7637687c74fc9bdeeeffb7ace0d04b734f] Defer initial
modeset until the first BlockHandler invocation
I'm unable to revert the first bad commit- I've also not seen anyone complain
so I'm assuming it's PRIME related:
