Change the gamma or contrast of a screen in Wayland

Desktop Silverblue
#1

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,

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.
