I'm running Linux Mint 9.I installed Argyll and gnome-color-manager but neither of those have a GUI. I need to configure my monitor colors. Right now the white looks a little yellow etc. and I want to do photo editing in Gimp. How can I get my monitor ICC calibrated?
Color calibration on Linux Mint
colors;monitors
There is hardware calibration available for Linux, if you can find the hardware to do so.  The Sp*der 1 and 2 are allegedly supported.  The Sp*der 3 maybe.    Here is an article on using the Pantone Huey (another inexpensive device that is actually supported on Linux).  The X-Rite Eye-One Display is also supposedly supported, but can find no instructive links, though this one is positive.This topic is not simple and cannot be summarized in a single posting easily.  Here are a couple of useful links on hardware calibration with the Sp*der and ArgyllCMS.The Linux Photography blog also has this article on dispcalGUI here.
