Is there any way to use Redshift on Raspberry Pi 4? I used redshift -P -O 3700 -g 0.7 -b 0.7 and it only works from time to time. Some times after restarting it doesnt filter the blue light anymore. Tried to enable openGL but still doesn't work. Or is there any other app that would dim the light?

1@brettinternet The funny thing is that I found a solution to this problem, but I can't post it now. Oh, well. It's called "eyesaver" and you can find it on github.– Philipp LudwigCommented Oct 22 at 5:52

Don't forget that I2C needs to be enabled for ddcutil to work. Commented Oct 22 at 5:52
