Redshift does not work in raspberry pi

[pickfire]

Hi, I had tested redshift with different configuration on Raspberry Pi. It seems that there are no changes to the monitor, is this an issue about the video driver?

If I remember correctly: Raspberry Pi does not support gamma correction. Thus, it does not support Redshift.

Okay, I think this is out of the topic now. I will close this until a solution is found.

Redshift now works with the experimental Raspberry Pi OpenGL driver.

Nice! Thanks a lot.

Hey @mskwon ! Is there any thing I need to tweak to get it to work on Rpi ? Doesn't seem to work on my side, can't initialize the geolocation :/ Thanks

I recommend setting dawn-time and dusk-time in the config file redshift.conf. Easier than dealing with location services.

This wont make it work because randr gamma control is not implemented yet but it makes it not break because of the provider.

Care how to share you got this to work?
I can confirm that the GL driver that Raspbian (now Raspberry Pi OS) includes doesn't resolve this issue. The driver can be selected within raspi-config, however upon rebooting the Pi and restarting redshift (which is running), the visual effects (colour temperature, brightness, gamma) are not produced. I have also tried this by installing other Debian distros on the Pi, where I have confirmed redshift to work on those distros but on other architectures, i386, amd64. I have included the raspbian repository on those distros to enable the GL KMS driver, but still to no avail.
