--- Comment #2 from Martin Gräßlin <mgraesslin at kde.org> ---
I think that's outside the scope of powerdevil. Waking up the connected outputs
is something the windowing system (e.g. X11, KWin_Wayland) needs to do.
Powerdevil has no control over dpms, that's on X11 completely handled inside
X11, it doesn't know whether the screen is on, whether dpms is in and has no
way to end it.

If the problem is also present on KWin_Wayland the bug can be reassigned to
KWin, for X11 it's outside the scope of our software stack.
