Bug#997794: xscreensaver: systemd integration leads to spurious deactivations (unblank) on desktop

[Jamie Zawinski]

I don't understand why you are having trouble logging with 6.02. Did you launch 
it as xscreensaver -v -log log.txt?

Investigating this in 5.x will not be helpful, because the flow of control is 
completely different with 6.x's new security model.
