Public bug reported:
Binary package hint: gnome-screensaver
Screensaver (skyrockets) freezes after running for about an hour,
sometimes longer. This occurs every time the screensaver is left to
run without keyboard or mouse input, eventually the animation freezes.
Moving the mouse clears the screensaver and the normal desktop
reappears, but always the system clock has stopped at about the same
time as the screensaver froze. System time must be reset manually.
I was able to ssh into the system while the screensaver was frozen and
htop (top would not run via ssh) showed 'nan' for every instance of cpu%
listed. The newest (highest pid) process was artsd, and attempting to
kill it via htop broke the ssh connection.
Both top and htop worked via ssh when the screensaver was running
normally, both showing normal processor activity. Computer sleep and
display sleep are both set to 'never' in power management.
System is AMD64 with nVidia. Will attach lspci. lsb_release returns:
