I have this problem too. Clean Edgy install with all updates. Right after system start screensaver (GLMatix) works fine. But after first occurrence of 'monitor sleep mode' screensaver never shows - screen just fades (as usual) and goes completely black (bug). No screensaver appears.
Temporary fix that works for me - kill gnome-screensaver and run it again. -- Screen saver showing blank screen with libGL 3D driver https://bugs.launchpad.net/bugs/65810 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
