registry: adding output 41
gamma control of output 41 failed
calculated sun trajectory: dawn 22:46, sunrise 23:34, sunset 13:07, dusk 13:54
setting temperature on output '41' to 4000 K
Has anybody had any success with these or another similar program?
I suspect the issue here is that the video drivers don’t support modifying gamma. That was a problem with the Raspberry Pi for a while. I’m not sure what it would take to support it either. At least the drivers are open, so there’s a chance it could be added if that is indeed the issue.
