I am trying to run a Plasma session as a different user from bash by running sudo -u $TARGET_USER dbus-launch --exit-with-session startplasma-wayland.
However, when trying to do so, I get an error "Could not create wayland socket".
My goal is to start a Plasma session as a specified user, wait for the user to log out and continue running the script.
- Does anyone know how I might be able to fix this error?
- Do you know of another way to start a Plasma session as a different user and wait for the session to exit?
I also tried to do the same using the sudo --preserve-env --set-home XDG_RUNTIME_DIR=/run/users/$(id -u $TARGET_USER) switches.
When doing so, I get the following messages repeatedly:
No backend specified, automatically choosing drm
kwin_core: Failed to take control of /org/freedesktop/login1/session/_311 session. Maybe another compositor is running?
kwin_wayland_drm: Failed to open drm device at "/dev/dri/card1"
kwin_wayland_drm: No suitable DRM devices have been found
However, logging in to the tty with the $TARGET_USER directly and running dbus-launch --exit-with-session startplasma-wayland works properly as expected.
