A way to edit colur saturation in linux? (R/G/B seperately)

I don't want to use the hardware tool on my monitor. I just want a way to do it in linux.

That's DE specific. For example in Gnome I can select color profiles for my monitors in settings.

You can use ddcutil if your monitor support DDC/CI

No idea, it is a LG Ultragear 32GR93U. Also I use KDE.

The kde gamma editor is sadly found wanting on most occasions.

Check out https://github.com/libvibrant/libvibrant if you are using X11.

 

EDIT: If xrandr --properties|grep -i ctm returns a result you can do it with xrandr, which would be easier...

Yes it returned a result. How do I use it, does it have a KDE frontend?

Does it return more than "CTM: 0"?

Looking deeper, you will want https://github.com/libvibrant/libvibrant. There is no UI for it, it's just a cli tool, but it's simple to use.

If the thought of "building it yourself" sounds a bit daunting, tell me what distro version and arch you are using and I'll package it for you...

I've just updated my system to Qt6, so have a bunch of tools I've written that need updating from Qt5 - if you get the cli tool working I should be able to knock up a GUI pretty quickly if you feel the need.

gThumb - an image viewer and browser for GNOME.

I run in in Linux Mint.


Click on the little paint brush icon top towards the right. All the edit options are now visible.  The 3 dots in a pyrimid shape give access to the colour levels plus brightness, contrast etc.

I have Manjaro KDE. KDE needs a tool like with that has sliders so you can adjust anything you want  it is transparent accept the words & slider so you can see the whole screen chsnge as you do it.
