I have a new 27" iMac, on which I run Fedora 15 (with no Apple OS) — just boot straight to Linux.
The colors are basically accurate to my eye, but the white point is much higher than I'd like (that is, everything is quite blue). I suppose it's 9300K, and may be due to fancy LED backlighting or some such. I don't know; I'm a software guy.
I'd like to adjust it to a more comfortable 6500K. In the olden days (including my old LCD monitor), one would just push a button on the monitor and select that from the menu. On an iMac, of course, that's not really an option. Can I do this in software instead?
I know that full-on profiling and calibration software runs on Linux, and I may get to that eventually, but for now I'd just like a simple option. What should I do?
