When playing DVDs or videos through VLC, the screensaver kicks in even though "disable screensaver" is ticked in tools->prefs->advanced->video. I have no idea why.
I have another machine with very similar hardware & software packages installed (nvidia accelerated driver 185 on both) and the setting works correctly on the other machine.
Where would I start digging to figure this out?
Oops, I just thought of this; it might actually be a big deal. (/facepalm)
the biggest difference between the two machines is the one that works correctly is 32-bit and was first installed with the Karmic RC release, then upgraded to "official". The one that does not work is 64-bit, installed from the "official" release.
