Thanks for your bug report. The first one on the list, do you mean the "4D Hypertorus" ? >From bug #58963: This could be a problem with some 3D screensavers taking down your machine. It is probably nothing wrong with gnome-screensaver itself, but your video drivers. What kind of hardware (esp. graphic card) do you have?
Can you please try running "/usr/lib/xscreensaver/hypertorus" in a Terminal window, and see if it crashes your machine? ** Changed in: gnome-screensaver (Ubuntu) Status: Unconfirmed => Needs Info -- Changing Screen Saver locks up entire system https://launchpad.net/bugs/60438 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
