In advance of being in a position to properly calibrate my dual monitor set-up under Ubuntu, I really need to move from using Nvidia's Twinview to something else as Twinview is seen as one single large Monitor. From a colour calibration point of view this is not too useful as each monitor needs to be calibrated separately.
Does anyone have any good tips, experience or recommendations as to the best way to go about setting up dual monitors that will allow me to calibrate both my monitors independently using Xinerama or another solution?
The gfx card I have is an Nvidia FX580 if that helps.
