I allowed the automatic update on the netbook last night. All seemed to go well up to and including the message that it was finishing off the install. When next I looked I had a black screen with a white square cursor. I left this overnight, in case something was still running in the background, but it wasn't.
A reboot brought the same display. I was able to get a level3 login, both as user and root. Can someone advise me where to look now? Thanks
