After upgrading to Xubuntu 13.10 I rebooted once and found that after login, regardless of account, I end up stuck after the login window disappears, with a movable pointer and the background from the login screen. I am running ecryptfs on the main account's home partition but even the guest login yields the same result. What do I need to fix this?
(I can reach a text terminal so I can post logs on request.)
(I've tried this question's solution to no effect: Can't login after upgrade)
Reinstalling lightdm and xubuntu-desktop also had no effect.
