[ale] Xubuntu 11.10 unable to login via lightdm

It's seemed that recently I've had nothing but crummy luck with my Asus Eee
netbook. Most recently I'm having an issue logging in via the lightdm login
manager. When I log in the screen flickers to a black terminal for a moment
and then I'm booted back to the login prompt again.

Thinking it was a video driver issue I blacklisted the radeon driver and
installed the fglrx package. I received the same results as before. I've
skimmed through several log files as well but I've not found anything
particularly incriminating, then again I'm not really sure which logs I
should be looking at so I could be missing it. I'm not sure if it helps but
I should probably also note that the last time this successfully worked was
the other day before I had to hard reset the system due to a graphics driver
bug I've also been trying to hunt down on this thing.

I am able to "sudo startx" successfully from tty1 after logging in to
console as my normal user. I assume lightdm does some policykit and dbus
magic that startx does not. I have no idea if this would have anything to do
with the issue here.

I'm open to trying about anything at this point. If anyone's got ideas, I'm
all ears. I've tried everything that I can think of with my limited
knowledge of the new ways Ubuntu does things these days (what was wrong with
/boot/grub/menu.lst? :-P ).
