I have this issue from time to time on both laptop and desktop (both having single-head configuration).
laptop: ATI Radeon x1250 Ubuntu 11.04 x86, kernel: 2.6.38-8-generic desktop: ATI Radeon HD 2600XT Ubuntu 11.04 x86, kernel: 2.6.38-8-generic-pae Both machines have Unity running. I can't tell if running classic gnome or classic gnome without compiz can fix the issue. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/45018 Title: Unlock screen is invisible with Nvidia twinview To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-screensaver/+bug/45018/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
