Dan: I tried changing to relaxpermissions=2 and rebooted, no change. Why 
does gdm restart (or gdm stop) return "GDM already running. Aborting!" 
.  I tried the gdmflexiserver cmd as detailed in custom.conf, i.e. - 
gdmflexiserver --command="UPDATE_CONFIG security/Relax Permissions=2" 
returned 'OK' so I think that got it, but I'm a little confused by the 
above error(s).

The root user may not be allowed to change permissions of the files on an nfs-mounted /home directory.  NFS defaults to the "root_squash" option.  You could try exporting /home with the "no_root_squash" option. 


Thanks Rob, that fixed it! Unfortunately it brought up another problem: now my login screen goes blank after I enter my username and password and eventually returns to start all over again, i.e.- asking for username and password. Any help would be greatly appreciated.
