There is no contrast and brightness settings there that i know of, but you can install kgamma5 for gamma correction

someone told me that there must be setting of "color correction" or something like that, but its missing, only gamma settings are present, BUT on wayland session even it is missing.

This is all i could find https://wiki.archlinux.org/title/KDE#Co … C_profiles

i have installed that one, got color correction tool, but got error "You need Gnome Color Management installed in order to calibrate devices", even when gnome-color-manager is installed on my laptop.

I think brightness and color corrections are done more by the GPU than your compositor since your GPU talks directly to your monitor. If you have NVIDIA settings, you can calibrate them there. Not sure about ADM though as I've never used AMD.

i have an intel gpu, you know what should i do to calibrate my monitor, because it's too contrast?

Sorry for some reason my post posted twice.

Perhaps just do it via hardware, your monitor settings. It's also the simplest.

sc6ut · 2021-08-18 17:08:05

i have a laptop, so i cant do it via hardware, so i need a "software way".

d_fajardo · 2021-08-18 17:12:58

So the brightness key on your laptop doesn't work as well?
I found this.

EDIT: It loos like udev could help.
You can also try xcalib, xgamma

xcalib and xgamma are good tools, but they are not working on wayland session.

No colour management on Wayland unfortunately https://community.kde.org/Plasma/Waylan … management

sc6ut · 2021-08-18 18:58:02

It's probably expecting that daemon to be prelaunched which e.g. gnome would do. But you won't fix this on wayland regardless and on xorg the KDE built in kgamma should do the job

sc6ut · 2021-08-18 19:37:24

Even on xorg session I can't fix it? Gamma is a little bit different thing, my display is by default too contrasted, so I need to decrease it.

V1del · 2021-08-18 19:46:02

Well as you're on KDE, why not use KDE's own kgamma5 to do it?

sc6ut · 2021-08-18 19:48:42

Because it does not have contrast setting, it has only gamma settings, that's why I'm searching for another tool.

sc6ut · 2021-08-19 18:33:27

Never mind, I will use xcalib to adjust contrast. SOLVED.
