Doesn't colord already push vcgt tag contents to the video card? On macOS, this is done through the display manager, no program directly modifies the video card LUT. I'm pretty sure it's the same on Windows in the modern era - it used to be every display calibration program came with a helper program that would launch at startup time and apply the calibration curve to the video card LUT. -- Chris Murphy _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
