I am using 7.10 Gusty Gibbon on a Dell Dimension 4500 1gz, i had the same problem happen to me. It really irritated me, after 15 minutes i would have to unplug the computer and restart. I wasn't able to change the screensaver from the screensaver preferences-- my system would hang. I tried changing parts of the gnome-screensaver configuration file in my home folder, with no luck. I did a search of my system for "molecule" and found the screensaver program itself was located at /usr/lib/xscreensaver/molecule. I deleted the buggy screensaver and was able to select a better one from the preferences (the molecule screensaver, at this point, is gone forever). Here is a step-by-step of what i did:
1. open the Terminal, type "su" and press return 2. enter your root password (and press return, of course) 3. enter "rm /usr/lib/xscreensaver/molecule" and press return The molecule screensaver is gone, you can now select a better screensaver. I am guessing this would work with Feisty, but i am not completely sure, it does work for Gutsy Gibbon. I hope this is helpful for anyone with this problem. -- Selecting the Molecule screensaver makes the PC freeze. It is completely unresponsive. https://bugs.launchpad.net/bugs/106060 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
