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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/948180 Title: Ubuntu 12.04 beta1: screen remains blank after screen saver (nvidia) Status in “gnome-screensaver” package in Ubuntu: Confirmed Bug description: Ubuntu 12.04 beta1 Steps to reproduce: * Install nvidia driver as recommended * Go somewhere and wait a few minutes * Return to PC, screen is black * Move mouse Expected result: * Unlock screen Actual result: * Black screen, only mouse cursor visible Additional info: Bug is present for years and has apparently never been fixed --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
