Hi,

Just to add to my previous comment (#40). I'm still experiencing problems and have the latest nvidia drivers installed. I tried running "unity --reset" as suggested in some posts I'd read from people experiencing similar problems. This gave the following:

The script has hung as well. I'm posting this here due to the "Warn: this should never happen. you should probably file a bug about this." messages in the output.
