How reproducible: Always. Steps to Reproduce: 1. Turn monitor off 2. Turn monitor on Actual results: The screen does come back, text VT and wayland work, but X screens remain blank. I have to ssh in and run export DISPLAY=:0 xrandr --output DisplayPort-3 --mode 3840x2160 to get it back. Expected results: X comes back automatically. Additional info: This is on a trashcan macpro. Radeon gpu and a UP3214Q dell monitor.
Hi, Thank you for your bug report. With display port turning a monitor off / on causes X to see a monitor unplug and plug-in (nothing we can do about this, this is just how dp works). If you're running gnome3 then gnome-settings-daemon should automatically re-configure (and enable) the monitor when it gets plugged back in. If you're running gnome3 and this does not work, please file a bug for this against gnome-settings-daemon here: https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-settings-daemon Note please do not use Fedora / Red Hat bugzilla for gnome bugs as the gnome developers do not closely track RH bugzilla. If you're using another desktop environment please file a bug against that desktop environment, bringing up the monitor again after a hot-replug really is the desktop-environments task. I'm going to close this bug as notabug since there is no notourbug resolution ... Regards, Hans
