Yes, it freezed "some time" (probably the cycle time) after the start
of the first GL screensaver.

Yep, I just tested again, I started xscreensaver-config, selected a GL
screensaver in demo mode, then clicked on another screensaver, and it
freezed at that moment.

I'll try to do more tests (changing to another NVidia graphic card,
etc...), and I'll try to find some configuration differences between
this host and the other FreeBSD 6.1 / NVidia host I'm using, and which
have no problems with GL screensavers for months now, with same
version of nvidia-driver.
