All of a sudden, on logging in, I am getting an error saying that
"User's $HOME/.dmrc file is being ignored" plus a load of other stuff
which I can't remember but which basically say that any changes I make
to my desktop configuration will not be saved and that the file must be
owned by me and have 644 permissions.
Well, I've checked the file and, surprise, surprise! It's owned by me
and has 644 permissions.
So, why am I getting this error? What can I do to get rid of it?
