I tried to install XBMC on the Nexus 7 but when I logged out of Ubuntu and into XBMC the screen went blank with only a cursor visible.
No problem, I thought, I will just reboot the Nexus 7 but I have auto-login setup so it just tries to boot into XBMC again.
I'm now stuck, unable to boot into Ubuntu. I presumed my only way out IDF to reinstall, this time without auto login.
