I installed updates, GNOME3, xampp, netbeans and a set of drivers. I went to restart the machine, and when coming back on, it hangs on a purple screen trying to turn back on. When I try to tap escape in order to get into the "safe" mode, it still hangs on the purple screen then eventually displays
^[^[^[^[ on the screen. It doesn't respond to keystrokes after that, but it does respond to the power button - it shuts back down gracefully, with the Ubuntu logo.
I booted into the cd and just ran it from there, so I'm thinking I can try and fix whatever damage is done and try to boot back from the hard drive. Any ideas on what went wrong and how to fix it?
