Joining the modern era: Xinerama to XRandR

[Noah Cutler <sit1way@xxxxxxxxx>]

Got RandR setup in place here with a 3 monitor setup, but have hit a sticky wicket relative to previous Xinerama setup (which I have reverted to until I find a suitable workaround).

With Xinerama we can stich together separate X screens under a single large display. This allows me to use my monitor calibration/screen inversion application xcalib, on a per screen basis.

For example, by default all screens are inverted (i.e. black background) but sometimes I need to see a website I'm working on as it really looks against a white background. With Xinerma I can toggle background color on a single monitor. With RandR all 3 screens invert at once, which is jarring on the eyes.

Is there way to get RandR to simulate Xinerma multiple pseudo separate X screens? Barring that, another calibration/inversion program that allows one to change state on a per physical monitor basis?

xcalib only works with screen x/display :x and RandR only has a single screen, thus the all-at-once jarring state change.

Thanks for ideas
