Error while trying to stop Plasma

[ggeorgo]

I am on Manjaro, Kernel 6.9, running KDE Plasma 6 on Wayland.

• systemctl stop display-manager (OK)
• systemctl --user -M my_user_name stop plasma : Failed to connect to bus: Host is down Failed to stop plasma.service: Transport endpoint is not connected See user logs and 'systemctl --user status plasma.service' for details.

And then, it fails when I am trying to remove modules:

• modprobe -r nvidia_drm nvidia_modeset nvidia_uvm nvidia  1 ✘ modprobe: FATAL: Module nvidia_drm is in use.
