I am trying to set up the nvidia-current drivers for one 27" 2560x1440 QNIX 2710 in landscape mode and one 24" 1920x1200 HPw2408h in portrait mode (physically rotated clockwise, software rotating screen counterclockwise to compensate). Without touching the xorg.conf, the hp monitor worked and the QNIX did not (i'm guessing this is because the hp could use a valid EDID). I got the QNIX working by tweaking the xorg.conf, but now the HP will only use 800x600 resolution, despite my specifying otherwise in the xorg.conf. I don't see how I can make the HP work while EDID is disabled in xorg or how I can get the QNIX working with EDID enabled.

Here is my xorg.conf file. Any ideas?
