I recently came into possession of a neat little 1680x1050 resolution monitor. My days of dreaming for a dual monitor were over...or so I thought. I've gotten everything to work both with x11 parameters inside of xorg.conf.d and also with xrandr initially (that is, I've switched over from xrandr to the X11 config, but may switch back, in either case they both do the same thing.);
So it works, but this little sucker isn't necessarily a spring chicken, so it's color correction is off. I've worked in imagery for a long time, so I'm fortunate enough to own a monitor calibrator, and I found a nice lightweight tool called xcalib that'll let you load previously generated .icm or .icc color profiles.
The problem is, I can't seem to figure out how to specify to xcalib which monitor to load the settings to. I don't even know if this is possible. Having two X sessions seems crazy, and trying to add extra "screen" parameters and monitor parameters in xorg.conf.d isn't really differentiating things.
More accurately my question is, in the tl;dr sense of things:
Does anyone know if I can specify two separate "screen's" (or "displays", whatever you want to call them) inside of X that I can, later, individually have xcalib apply calibrations to?
At the moment, when I issue an xcalib command such as:
Code:
xcalib -d :0 /usr/share/local/color/icc/some_color_profile.icm
It seems to, strangely enough, apply solely to my new, smaller, monitor, and not to my other monitor. But I've also learned that looks can be deceiving and I don't know if it's applying it to everything on both screens.
