--- Comment #21 from Michel Dänzer michel@daenzer.net --- Plymouth shouldn't get the values with drmModeCrtcGetGamma — there's no guarantee that the CLUT contains suitable values at that point (e.g. the hardware could currently be programmed for a different colour bit depth in the first place). It should initialize a suitable (e.g. linear) gamma ramp and set that with drmModeCrtcSetGamma.
