if filesystem is full gdm fails to login users without warning

If the file system is full, users cannot login via gpm: the
system tries to start an X session, but fails and returns to
the login window. The user is not informed what causes the
The problem here is gdm lacks any facility to display errors or dialogs
of any kind, it only logs them to syslog. It's a large fix that's required.
I looked into fixing this more; the problem is actually worse than I thought.
gdm can display errors, up until it exec's your session. After that it's
hard to know what to do; gdm isn't running out of space I don't think, I think
the apps launched in .Xclients are running out of space. At that point gdm
is out of the picture. So, this bug is actually "many apps have
bad error handling" I don't think it's a gdm bug.
This problem is basically unfixable since it's so general; specific bugs against
specific apps would be required.
