I'm running Xubuntu 10.10;

Xfce 4 Desktop Environment
version 4.6.2 (Xfce 4.6)

The login GUI is whatever installs with Xubuntu/xfce. Must be a
front-end for 'gdm'.

I am NOT running as root - not at all. I boot using grub. I'm
presented with a GUI login screen. Up until yesterday afternoon, all
was well. My username and "other" showed up as default users. I
selected my username; input my password; JOY!

All of a sudden, after I input my password, I'm recycled back to the
GUI login screen when I select my username.

However, I can select "other", use 'root" as a username with the
appropriate password, and again JOY.

I can also go the long way around: from grub, use the "recovery"
option. From the CLI, login using my username/password, then do a
"startx" - again JOY.

The problem only occurs when I'm presented with the default GUI login
screen, and I use my username/password.
