thanks to help from here I am using Twinview very happily - but with one small nit -
when I start an openGL fullscreen app like bzflag, Google Earth or stellarium, it is centered on my screen. Which means it is split right down the middle between the two screens - hard on the eyes!
is there any way to specify the app should run on only one screen?
I am guessing, NO
but I thought I would ask...
Of couse I have an alternate xorg.conf which does not do twinview and uses only the DFP screen, so I can switch the conf files and restart X. But it would be nice to not have to do all that.
