I have a TV connected to my computer by HDMI and some 10 - 15 minutes after turning it off my computer displays flicker, windows from the TV move over to the other monitors, etc. I would like to prevent this behaviour, leave windows on the TV, etc.
I have found suggestions to use gsettings set org.gnome.settings-daemon.plugins.xrandr active false, however this setting no longer appears to exist as of my version: Ubuntu 21.10, GNOME 40.4.0.
Additionally there have been suggestions to set amdgpu.dc=0. I did not even check if this resolves the screen issue as it completely disables audio over HDMI when I tested it -- which defeats the purpose of having the TV hooked up to the computer.
- Happens in both X11 & Wayland
- Currently have an xrandr config in ~/.screenlayout that configures my monitors quite well, if they would just stay put
- Have tried disabling / enabling all power saving features on the TV itself
