That directory should have been created early in the boot with correct
ownership and permissions by /usr/lib/tmpfiles.d/x11.conf, which is part
of the systemd package. Is that not happening on your system?
What is the output of "systemd-tmpfiles --boot --dry-run --create" and
"systemd-tmpfiles --tldr"?
Are there any errors logged in the systemd Journal before gdm starts?
Specifically, the relevant part of the log is what's between
Starting systemd-tmpfiles-setup.service - Create System Files and
Directories...
and
Finished systemd-tmpfiles-setup.service - Create System Files and
Directories.
As a result of #1120032, you should see at least one message "Duplicate line
for path "/run/lock", ignoring", and possibly more.
When I looked, indeed /tmp/.X11-unix is owned by the gdm greeter user
If the overall system is working as intended, by the time gdm starts,
those directories should already exist, therefore the gdm greeter should
not be able to create them owned by itself, even if it wanted to.
