screenshot of tearing effect
When xrandr -o inverted is run, the resulting image is split down the middle.
This happens 95% of the time; it has worked once or twice without tearing.
Rotation can be activated through unity-control-center Display Settings
rotation field, and that reliably works fine. When xrandr -o normal is run, the
display returns to normal (although bug #1376760 is observed). xrandr -o right
and xrandr -o left also reliably work without issue; this only occurs on xrandr
-o inverted. The same behaviors are observed with the longer form of the
command xrandr --output eDP1 --rotation inverted, etc.
This has also been reported at <a href="https://github.com/pfps/yoga-laptop/issues/28">https://github.com/pfps/yoga-laptop/issues/28</a>,
which uses xrandr commands to invert the display.
