Description Rafael Ávila de Espíndola 2016-09-24 14:42:24 UTC

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
