Could this be the same issue as <https://bugs.gnu.org/36508>?  In short,
Guix doesn’t guarantee that the “gdm” user will have the same UID if it
gets deleted and recreated (which happens when you remove the GDM
service and add it again).  You can fix this by ensuring the owner of
the files under “/var/lib/gdm” is the current “gdm” user.
