I was able to get them working. The only problem I have is that I may
have over-tweaked them. At first, the panels went all the way across
but now they stop at the first monitor. I may be responsible for this
by playing with the NVidia-settings app to much, but haven't been able
to find where that option is (there is a GUI for people using Fiesty
and the restricted driver from NVidia. Just type "gksudo
nvidia-settings").
