Sudden authentication error when starting an x-session
Slackware 9.1, kernel 2.6.3, latest dropline gnome.
Everything was working great and then one day while I was playing videos gmplayer started giving errors (which I don't have as I didn't think much of it at the time). This was after already playing many videos in that session, and the computer had not been restarted in weeks because everything was working so well.
I then exited my x-session and started it again to see if this would clear up my mplayer problem, and gnome would hang on starting. If I switched to the terminal I started this from (ctrl-alt-f1) I could see what the problem was:
"gnome-smproxy: unable to connect to session manager
Window manager warning: Failed to open a connection to a session manager, so window positions will not be saved: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed"
Many more errors come up after this, but they all give the same authentication error as above as their root problem.
Eventually gnome will load but a large number of my apps will not work correctly any more and it takes about 20 minutes for gnome to get passed all these errors and start. Also, when I try to log out of my x-session it just hangs again.
I didn't install anything or change anything during this session, it just happened suddenly while I was using gnome. I've rebooted and that didn't help. It's like a file has become corrupt, but I have no idea how to locate the file causing the problem, and even if I did I wouldn't know how to correct it.
Under the root user, everything works just like it always did, gnome does not hang on starting and there are no problems with mplayer. ...but of course, I don't want to have to live my life logged in as root.
I'm thinking I will re-install dropline gnome and see if that solves my problem, but it would be nice to know what caused this in the first place.
