</div>You should not be able to run weston at all without XDG_RUNTIME_DIR<br>
properly set up.<br>

</div>XDG_RUNTIME_DIR is where the Wayland socket will be, so if the<br>
compositor and the client have different runtime dirs, the client<br>
should usually fail to connect.<br>
<br>
Is it possible that you get a fallback to X11 via Xwayland?<br>
<br>
Are you sure you don't mean /run/user/1000?<br>
<br>
XDG_RUNTIME_DIR may also be used for allocating wl_shm buffers - are<br>
you running out of disk space there? (The space will hopefully get<br>
freed as soon as the client reserving it dies.)<br>
<br>
<br>
Thanks,<br>
