-Installed the latest update
-Now I can't get past the username and password login screen
-If I change sessions to either GNOME or GNOME Failsafe I get the "HAL" error message but I CAN get to the desktop.
-Once there the optical drive and my USB external drive won't recognize so I can't backup and reinstall.
-Also no Internet connection while in these two sessions.
I know next to zero about the command line so any help would be incredibly appreciated.
