After typing in my password in
lightdm, I get a blank screen and then I'm returned to
lightdm. I'm unable to find any obvious problems in
/var/log/Xorg.0.log (though I'm happy to post them if they would be helpful).
Current workaround (but imperfect): I can start X from a console but when I do this, I run into another problem which is that sound is unusable (despite attempts to restart
mpd). I suspect that the original

One other datapoint: From
lightdm, I can log in as a different user (one that's basically in default state) and everything works fine -- Xfce starts up and sound works for them.
Does anyone have an idea of how to debug the
Tried some of the actions from Ubuntu gets stuck in a login loop -- my

I also tried
dpkg-reconfigure lightdm (no change).
- Tried reinstalling
apt-get purge lightdmand
apt-get install lightdm(problem remains).
- Also tried deleting
straced the root
lightdmprocess (once for my user logging in, once for the dummy user logging in) but it doesn't reveal much file system access to paths in the users home directories.
