I solved this problem (the white screen) for my video card X600 on the asus w3 laptop by replacing the default ati driver with the xorg-driver-fglrx-envy package.
Still, I think that when apt upgrades the graphics driver it's worth switching Compiz and FX off in case there are problems on the next boot. -- Compiz not working and machine unusable after latest upgrade https://bugs.launchpad.net/bugs/236488 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
