In gnome-color-manager I try use argyllcms to get the ambient level for the following sensors: * DTP20 * DTP92Q * DTP94 * MonacoOPTIX * i1Display * i1Monitor * i1Pro * Colorimtre HCFR * Spyder 2 * Spyder 3 I already know these devices: * ColorMunki - Ambient - Ambient Color * Huey - Ambient So I know when to gray out the button, which of these sensors support reading the ambient light level? It would also be good to know if the sensors can measure the color of the ambient light too. From looking at most of the websites, it's not immediately obvious which sensors have ALS sensors, and this also doesn't tell me if the ALS are supported in argyllcms. Thanks. Richard.
