Is it not available or you can turn it on and off but it doesn't take effect?

Comment 5 Nate Graham 2021-08-10 15:16:04 UTC
Works for me. I suspect some packages may be missing, maybe?
Comment 6 David Edmundson 2021-08-10 15:19:27 UTC
Unlikely to be missing packages.

There are 3 possible causes:

1) the driver doesn't support gamma ramps
2) some other software is changing the gamma ramps back (i.e kgamma, or redshift)
3) we have a bug in our code

To rule out 1, can you run:
xrandr -q --output DP-2 --gamma 1:1:0.5 

and confirm your screen becomes a horrible shade of greeny-yellow.
(where DP-2 is the name of your output from xrandr -q)

Set everything back to 1 to rest.


Can you also include screenshots of your night settings

So when you run `xrandr -q --output eDP-1 --gamma 1:1:0.5`, does everything turn green?
