While updating to Precise, I lost one of my startup scripts that sets ARGYLL_IGNORE_XRANDR1_2, but I assumed it was still active and only tested deactivating it. So now I can report, that the current 302.11 beta driver does load a single LUT when ARGYLL_IGNORE_XRANDR1_2 is set. I am away from my second screen for a few days, can't test that yet. But as xrandr is working now for screen switching (in contrast to previous Nvidia drivers), I have high hopes for that. But, while I did my tests, I noticed that dispwin would report the internal laptop screen as screen 1 when solo and as screen 2 when running with two screens which makes automated setup scripts more painful than it should be. Or is there an easy query method that I missed? thx afx -- http://afximages.com/
