Description Tatsuyuki Ishi 2015-11-17 09:16:29 UTC 
Upgraded from 4.1 and noticed unusable graphics.

= DETAILS:
Almost whole screen (about 1024x768 out of 1280x800) are covered (being black).
VT or X.org doesn't matter.
Some text are shown in the black space but they aren't properly rendered and are hard to read. It also doesn't render all things it cover.
* Sorry for bad description

= WORKAROUNDS:
Downgrade to 4.2.5 worked. My IGP didn't broke by compiling kernel :)
