I haven't read or seen anything about how a multi-head may be affected
by applying a profile. Can each screen have it's own profile, what it
they aren't the same brand/size/type? I suppose one would just have to
pick their "favorite" monitor to use and hope the new profile doesn't
skew the others too much?

Yes, as long as the video driver you're using supports xrandr 1.2
(which, I think is all of them, minus the nvidia binary driver).

My setup has three screens on two ati/amd chips, and it crashed incessantly until I disabled xrandr, so the support may not be quite faultless.

Hello !
That's exactly one of my problem :p
I'm on an OpenSuse with an nvidia driver and two screens set up in twin view mode.
XRandr, xcalib, nvidia-settings and other tools consider my two screen as a unique x screen. This is very problematic because I can apply only one gamma curve that will affect both screens.
I tried a lot of configurations like separate x-screen, separate x-screen + xinerama... to have a gamma curve by screen.
But I didn't find any satisfying solution.
As anyone, an idea ?
Thanks a lot !

Hi,

Buy two identical monitors.
Try an ATI graphics card.
Try the Nouveau driver.
File a bug with Nvidia. Good luck, you'll need it. :-P
Other than that: no.

Get a Mac? Mac OS had multiple monitor support in 1987 (supporting mixed colour depths, resolutions, chipsets, non-rectangular layouts all without drivers!), and multi-screen profiling in 1993. I used a Mac IIfx with six 21" monitors in 1992. Think it cost > $30,000 though! People still often act incredulous when I drag a window from one screen to another as if it hadn't been normal for 25 years!
I'd love to see an OS X version of ColorHug. ArgyllCMS already works with things like Huey (but I'd prefer to support open hardware), and class-compliant USB stuff tends to play nice; All the usual libs are available either natively or via MacPorts/HomeBrew. I don't know what else it needs.
Alternatively, could running in a VM work? I suspect hardware abstraction would probably get in the way of getting native measurements from the monitor.

Ok, I wasn't fully sure that it was an nvidia problem.
I already tried the ask-nvidia-option but they didn't seem to understand what my problem was :p
Unfortunately getting an ATI (or a Mac) is not an option for us, our work requires theses.
Anyway, thanks for the quick, clear and cut answer ! :)
