Public bug reported:
This looks like a regression from the 5.13.0-20-generic kernel to the
5.15.0-17-generic kernel. The display works fine under efifb, but as
soon as the DRM drivers are loaded and KMS kicks in the display is
replaced by black with flickering white (apparently when what would be
on the output changes).
