I'm trying a bunch of alternative desktops that come with Debian 11 in a VM (gnome-boxes), that itself runs on Debian 11.
All of the desktops I tried (XFCE, Gnome Flashback, Cinnamon) can change the screen resolution, but if I do it in KDE, the screen just flickers a bit and gives up -- doesn't even show a prompt to keep the new resolution.
Is this a known problem, and is there a solution to this?
