Just installed KDE Plasma on my Ubuntu system to replace GNOME and Wayland. Mainly to get rid of an issue where my games would lose mouse lock, but now I can have two different wallpapers on both monitors and have a clock on my second monitor which is AWESOME.
I WISH I INSTALLED IT SOONER, I LOVE IT.
It is, up untill Plasma 6.8 (estimated release early 2027) Plasma can do both direct to X11, or direct wayland with xwayland support for legacy apps.
