In my case, there is no /var/run/user itself :)
Because I am not using wayland.

And if it is set while being seen
https://docs.freebsd.org/en/books/handbook/wayland/
I feel that non-privileged users will not be able to create directories there.
If the process that first creates the directory in /var/run/user is a
non-privileged user, one step is required to make sure that /var/run/user has
permissions like 01777 or rwxrwxrwt.

Also, I can't find the part of the sddm source code that makes the directory
there.
If UID is 1001, then just logging in with sddm and starting a session will
create that directory, is that correct?
