Description O. Hartmann 2021-08-27 13:17:57 UTC

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.
