| ... When I logged in I
| got an error message:
| 
| "User's $HOME/.dmrc file is being ignored. This prevents the default
| session and language from being saved. File should be owned by user and
| have 644 permissions. User's $HOME directory must be owned by user and
| not writable by other users."

This is asking you the change the data file ~/.dmrc permissions to
allow you, the owner, to write it, and to allow everyone to read it.

Note: nobody now has permission to execute it (755 would add execute
permission for each of: use, group, and other).

|  Today I finally used it to chmod
| my /home/jjj folder to 644 as recommended by the login error message.

Instead, you changed the permissions on the home directory.  As a
directory, the execute permision bits are interpreted as controlling
whether an entry can be looked up within the directory (the main use
of a directory).  You have said: nobody can look up things in this
directory.  Not very useful.

| Then I rebooted the main installation and was not able to log in at
| all! I rebooted the rescue installation and changed /home/jjj to 755.
| That did it. Now I can log in, and the error message is gone.

755 is probably correct.  The paranoid may prefer 750 (preventing
non-group members using the directory) or 700 (preventing group
members and fellow group members from using the directory).  On a
notebook you probably don't give logins to folks you don't trust.
