External Monitor from Laptop Dock shows black screen in fullscreen games
As per the title, when I boot a game into fullscreen or windowed borderless the monitor shows a black screen, however, if I take a screenshot the game is running and visible. If i move the game to the laptop screen, it shows as expected. Adaptive Sync is set to never.

AMD?
This sounds like a DRM issue
If AMD, you can try this
KWIN_DRM_NO_DIRECT_SCANOUT=1 before the game launch
Or put it in /etc/environment for a more permanent solution~/.config/environment.d/somefile.conf
better solution, no sudo needed and easier to manageHi! Sorry, it's an Nvidia card
Looks like I need to move my own configuration of this then 😜
Cause the issue, then once it's back to normal, do
ujust logs-this-boot | fpaste and paste us the url
And in $HOME which means more easily transferrableexactly
There's a lot of errors in there. Not sure which ones are important tbh, but this one looks fairly suspectish

When you load a game using
gamescope does it do the same thing?so gamescope works in windowed mode, but when playing at fullscreen the framerate drops down to 1-2FPS
(full framerate in windowed, and full framerate when playing fullscreen beforehand on the laptop screen)
hmmmmm, then yeah I don't know, sorry 😭 I hope someone else chimes in with some more helpful info
thanks for trying!
