Comment 26 for bug 1801609

More info here, as well:

If I only set the "Switch off after" Display setting to >1 Minute and leave
the other settings("Blank after" and "Put to sleep after") at 0(Never),
then the display wakes up normally!

This was tested on the originally affected system(s) and required no
customized xorg.conf.
