None of the advanced hardware here but the new driver works fine with DisplayPort.

Ran glmark2, and stellarium reproduced the view out of my window.  The Mate desktop is running OK, vlc video, firefox and thunderbird.

Older hardware.

Mate desktop running smoothly and all graphical utilities.  Ran glmark2.

None of my hardware uses nvidia-current, but all of it, as far as I know, uses ldetect.lst. 

If I were to update just that, would it be helpful here? And if I were to update it, how would I tell if it's actually still working?
