No desktop after 13.04 upgrade

[thogland]

Existing/working quantal Lubuntu system using lightdm/openbox. 'do-release-upgrade' ran with no errors, on reboot system displayed lightdm login screen. After entering password, login boxes disappeared, leaving the lightdm background, and no further response from system. Power button performed clean shutdown properly. Reboot into kernel 3.5 shows same behavior, as does selecting different environments (Lubuntu, LXDE, Openbox, Gnome, etc.). Mouse also functions... Reboot into recovery mode, check dmesg/syslog, no errors found except a udevd message that SYSFS is no longer used (related to Logitech mouse).

Corrected by booting to recovery mode and running root shell, 'mount -o remount,rw /', 'dpkg-reconfigure lightdm' and selecting lightdm as display manager. After rebooting, desktop appears correctly.

Unsure if this is display manager or window manager related, was unable to find any errors indicating either. Was unable to locate any release notes, etc. showing this as a problem. Can pull logs as desired.
