Hey Stewart,
Thank you, I'd like to borrow your ColorHug and I'll contact you off
the list about it.
Not matching color profile of a dual screen setup have been bane of my
existence, for any dual screen setup I managed to experience, I've seen
not-so-slightly matching color temperature that I could never adjust.
I assumed that I've been getting screens from different batches and
there's nothing I could do about that; also my knowledge of color
profiles is really dated -- I thought it was something really expensive,
finicky and doesn't work for Linux.
Alex.

What is the procedure for calibration? is there a way to do it in
Linux? Do I need a special device for that?
Yes, you need a device, but the procedure is simple. I can lend you my
ColorHug, a display calibrator that runs *only* under Linux. Takes
about 20 minutes to do a full calibration per screen. It spits out an
ICC profile that (should) be automatically picked up by your display
manager. Picky types recalibrate frequently. I do it annually, at best.
Most displays come set way too cold, so whites are blue-white out the
box. Your display will look a bit pink for a while until you're used
to it, but you should notice you can see a bunch more brightness
levels. If you're running a dual-monitor setup, make sure you
calibrate them both - having one eye-searing cold blue and the other
warmer looks terrible.
