Bug 258086: x11/xdm: powersave does not wake up
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258086



--- Description ---
Running 14-CURRENT (14.0-CURRENT #9 main-n248954-d396c67f26b0: Thu Aug 26
23:08:13 CEST 2021 amd64) with X11 (portstree is up to date) with a nVidia
GTX360 GPU and a DP connected screen, the screen doesn't show up when switched
off and powered on while the system was running in the meanwhile.

This behaviour is erratic and can not be triggered. The only way to revive is
to reboot or having the luxury of a remote connection to the host an "killall
xdm", sending xdm a SIGHUP.
