Public bug reported:
A few months ago, I started having a problem where my laptop would
freeze and require a hard reboot when I tried to wake it from
screensaver. I tried turning light-locker off; this fixed the problem.
However, now due to company policy, I have to turn light-locker back on,
and found that the problem still existed. After some searching, and
trying different things, I've found that if I set light-locker to
activate on screensaver *deactivate*, then everything works properly,
and when I wake the laptop from screensaver, I'm presented with a blank
X background and password dialog. If I set light-locker back to
activate on screensaver *activate*, then my computer continues to run
until I press a key or touch the touchpad, at which point it freezes.
Note, I keep suspend and hibernate turned off completely on this laptop,
and almost never run on battery. The above happens when plugged into AC
power. It would appear to be purely in the realm of light-locker and
the screensaver.
