I also have the same bug, with an nvidia geforce4 go 420 and nvidia proprietary drivers.

Disabling twinview is not an option because it's a notebook I use frequently for presentations. -- Unlock screen is invisible with Nvidia twinview https://launchpad.net/bugs/45018 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
