--- Comment #18 from Paul Menzel <pmenzel+bugs.freedesktop.org at molgen.mpg.de> ---
Martin, Pierre, is this happening only with MST (multi-stream transport)
monitors?

I have the same problem with a Fujitsu desktop system and the MST HiDPI monitor
Dell UP3214Q. Turning the monitor off, and trying to turn it back on does not
work.
