Since upgrading from 13.04 to 13.10 32bit, after a few seconds of opening XBMC, it freezes briefly and then sends me back to the OS logon screen. If I log back in without rebooting, it will do the same thing no matter what I'm doing, regardless of opening XBMC. Obviously I've tried uninstalling/re-installing umpteen times. I found similar articles about being logged off but none of them had to do with XBMC. I tried their resolution steps anyway, but without success. Any help would be greatly appreciated.
