I saw notes on http://argyllcms.com/doc/Installing_Linux.html about dual displays with N-Vidia Cards, and believe I am effected by this because when I run dispcalGUI I get: Enumerating display devices and communication ports... ...ok. Checking LUT access for display 1... ...ok. Checking LUT access for display 2... ...failed! Initializing GUI... ...ok. Loading LUT curves of current display device profile... ...failed! I am wondering are there any workarounds for calibrating both monitors? For instance, can I disable one of the monitors, restart X, calibrate that one, and then disable that one, restart X, and then calibrate the other one. Then, enable both, and they will both be calibrated, or does it not work like that? I am new to monitor calibration (If you can't tell). Thank you, Kyle Brandt Http://www.kbrandt.com
