Hi,
wrt macdrv_SetDeviceGammaRamp, the X11 driver has some validation in xvidmode.c->ComputeGammaFromRamp() because windows doesn't allow every ramp.
It might happen that apps try bad ramps and the screen simply gets dark without validation.
I'll see if i can copy/move the validation to gdi32 where the driver function normally get's called so that the validation is driver independent.
