I managed to start plasma wayland session on AMD RDNA4 card but keyboard and mouse are not responding. It didnt crash because i can see tray icons appearing while my startup applications are loading. If anyone wants to try, follow these instructions.
First disable SDDM or whatever display manager you are using, and make sure that your non-root account is in video group.
Install seatd and plasma
Enable seatd and dbus
Code:
# sysrc seatd_enable="YES" && sysrc dbus_enable="YES"
Start seatd service or reboot the system.
Create a script in your ~ directory.
Code:
echo "exec dbus-run-session startplasma-wayland" > ~/start_plasma.sh
Make it executable
Start plasma wayland by typing
As i said above, keyboard and mouse are completely cut once desktop appears. You wont be able to go to TTY. Its hard reboot from here, but Plasma wayland session definitely starts.
