Description David Pedersen 2016-12-24 23:08:06 UTC

Rotating X Window with xrandr or desktop environment settings, on my GPD Win (small handheld computer) results in a black screen on recent kernels.

It works as intended on 4.7.6 but has been broken since 4.8.2 (or a version in between, not packaged for Arch Linux).

This seems to have been resolved since upgrading to 4.9.2-1.
