I am confirming: same problem, although on Xubuntu Edgy Herd 5. The screen saver named "Molecule" causes the system to hang while it shows "Constructing Molecule..." on the screen. This screen saver is turned on in the default random rotation of screen savers, so it will eventually happen without any user intervention.
Steps to reproduce: Open Xfce Menu -> Settings Manager -> Screensaver Scroll to "Molecule" and click on it. It freezes the system even if it is only in the small preview window. Once the system is frozen, it does not respond to any key commands (eg Ctrl+Alt+F2 to try switching to another terminal and Ctrl+Alt+Bkspc to restart X both do nothing). However, once the power button is pressed, I can briefly see it having switched to another terminal before it shuts down. The computer on which this occurs is a stock Dell Inspiron 8000 notebook, which has an ATI Rage Mobility M4 AGP (rev 10) graphics card. I will post lspci -vvnn output and xorg.conf when I'm back on that machine. Is there any other output that would be helpful?
