Yes I have. It just sits there looking stupid.

Tried that, too. The last thing it does is exec /usr/bin/gdm -nodaemon, which is exactly what I thought it would and
should do from looking at the script. But there is no login.
Anyhow, I don't know how it could start a graphical
login program while I'm already logged in, so I didn't
expect that to help.
