Xscreensaver won't switch off display

My guess:
Qubes OS did modify xscreensaver to include some fix / improvement.
They probably installed it in dom0 with an Epoch Tag of 2 to avoid the package to be updated by the fedora repository.

The Qubes OS logo replaces the default flames on Qubes OS, that might be the change.

Related to that change: Default Screensaver (can I change the image back to the old one)
