It definitely needs to happen. More and more laptops especially are being
shipped with nVidia graphics cards (okay, I don't have real data on this, but
the last three I've randomly purchased have this) and they seem to struggle
really bad with light-locker.

You're right, it's really bad to have the GUI restarted after resume from sleep.
Kind of defeats the purpose.

I concur whole-heartedly. I will see if I have time to test it, but seeing that
every time I install a new environment, the first thing I do is swap
light-locker for xscreensaver. Can't be much worse than that.
