With the update to KDE Plasma 2.23, I decided to try enabling Wayland on my Arch Linux system. The first thing I did was install the following packages:
plasma-wayland-protocolsplasma-wayland-session
After I did this, I got a Plasma (wayland) option in the SDDM sessions selection. But, when I tried to log in, it simply returned to the login screen. Doing a little research I found this page and added the following to /etc/default/grub:GRUB_CMDLINE_LINUX_DEFAULT line:
nvidia-drm.modeset=1
and ran sudo grub-mkconfig -o /boot/grub/grub.cfg.
Now, the session tried to start, but all I got was KDE starting on two out of three screens, and then a gnome-do popup on the screen, and nothing else.
After, I switched back to X11 session in SDDM, I did notice a few things different after logging in:
- toolbar panels were larger
- no toolbar on middle screen
- screens were not in the right order
- keyboard did not work
Reboot …
More things seemed normal, but one screen was still not configured with panel, etc.
Enough time on this today – will try again in the future …
