I am running a Lenovo laptop with USB docking station with two external monitors connected to the dock. This setup has been working flawless until I upgraded to 6.7.
Now all 3 screens turn black the moment I plug in the docking station connector. I’ll get a couple of USB connected sounds until it will eventually kill the session and show a basic logon screen.
A few times I noticed that one of the screens was showing a dimmed out desktop for a second or so until it went back to all black.
I did a partial downgrade to make sure it really was the Plasma update and not any of the many other packages which got upgraded after a 2 weeks holiday break, and yes, downgrading like below immediately made all screens work again.
sudo pacman -U /var/cache/pacman/pkg/kwin-6.6.5-3-x86_64.pkg.tar.zst \
/var/cache/pacman/pkg/plasma-workspace-6.6.5-2-x86_64.pkg.tar.zst \
/var/cache/pacman/pkg/libkscreen-6.6.5-1-x86_64.pkg.tar.zst \
/var/cache/pacman/pkg/kwayland-6.6.5-1-x86_64.pkg.tar.zst
Plasma is broken now (error messages, no taskbars and whatever else) because of the partial downgrade, but I think I confirmed that one of the 4 packages is breaking my setup.
I can safely go back to a pre-update btrfs snapshot but was wondering if I should keep things and log a bug report instead?
