--- Comment #21 from Michel Dänzer <michel at 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.
