Change the gamma or contrast of a screen in Wayland

Hello Fedora Silverblue users and developers!

Does anybody know if it is possible to change the gamma or contrast in Wayland?
The colors on my laptop screen are a little bit washed out and I want to fix that.

I tried the xrandr and xgamma but they both don’t have any effect.

Is there some other tool I could use?

Thanks in advance,

Scott Trakker

Hello @scotttrakker,

Maybe look here for some info on Gnome and Wayland. https://help.gnome.org/users/gconf-editor/stable/introduction.html.en
I had to layer it on Silverblue. [edit]

I think it may have what you are looking for. Other than that, I guess it could be GPU dependent?
Oh you said laptop! How about the power and nighttime settings?

Hello Jakfrost,

Thanks for trying to help me!
I think you shared the wrong link (the link that you sent, links to the documentation of the Gconf-editor.)?

No I thought it was the right tool to use, and it may be still, but I am not familiar with it enough to be useful on this topic. I open it up and there are no keys setup, but I don’t know the gnome shell like I need to to use it properly. AFAIK it is the administrators goto tool for Gnome tweaking.
