You should not be able to run weston at all without XDG_RUNTIME_DIR
properly set up.

XDG_RUNTIME_DIR is where the Wayland socket will be, so if the
compositor and the client have different runtime dirs, the client
should usually fail to connect.

Is it possible that you get a fallback to X11 via Xwayland?

Are you sure you don't mean /run/user/1000?

XDG_RUNTIME_DIR may also be used for allocating wl_shm buffers - are
you running out of disk space there? (The space will hopefully get
freed as soon as the client reserving it dies.)


Thanks,
