"Absolutely nothing" is a bit ambiguous. I am still on bookworm and in
my case path is /var/log/Xorg.0.log.old (without .old it should be new
LightDM greeter session). I hope, you checked file modification time.
There is nothing in any log indicating non standard behavior, or
errors. There are messages of the session startup in the journal, and
then messages from session shut down, nothing in between.
Have you compared *user* session log with the case when ~/ is a local
directory?
I expect that errors outside of systemd scope should appear in
~/.xsession-errors. There is a chance that something is logged to
/var/log/lightdm.
Xorg.0.log is also properly stored in ~/.local/share/xorg, which
proves that the home folder is mounted rw for the user.
I would rather suspect something behind regular file read-write:
special files, locks, etc.
Ideas to try:
- $HOME on NFS instead of CIFS
- CIFS mounted from command line instead of PAM plugin
- Another lightweight session like fluxbox just to test if the issue
is specific to LXDE
Perhaps there is a way to enable more verbose LXDE logs.
