Do you mean the DAC's RGB lookup tables (for gamma correction)? The XFree86 VidMode extension allows gamma table correction for all drivers that support it. See the /usr/include/X11/extensions/xf86vmode.h header file, specifically the GammaRamp functions. For each component R,G,B there is an array of unsigned shorts. Different hardware/drivers can have different sized arrays so you should query the size with XF86VidModeGetGammaRampSize. Retrieve the current LUT with XF86VidModeGetGammaRamp. Mark.
