Comment 33 for bug 948180

Just a note to Vanessa - I have this same problem on precise with ATI - if I leave the machine for a day or so when I come back I get the blank screen with just a mouse cursor issue.

Today I found that if you just wait - on the order of 4-5 minutes - the login prompt will eventually show up. Running top I found that chromium was taking up a lot of CPU, so I restarted it, but I'm not sure if that is related.

In any case, there is obviously something going on here but next time it happens wait and see if it eventually does present you with a password or a desktop screen.
