Description Ross Burton 2007-08-23 08:40:49 UTC

If I use something like Argyll CMS to set a custom LUT on the video card so that my display is correctly calibrated, when the screensaver kicks in the LUT is discarded.  This is because of the gamma trick to fade the screen to black, setting a gamma value explicitly overrides the LUT.

Please save and restore the LUT after the fade is completed.  This can be achieved using XF86VidModeGetGammaRamp and XF86VidModeSetGammaRamp.
