Need help adjusting screen color on a new laptop

General system Kernel, boot, graphics & hardware
1

So I recently got a new laptop and inserted the SSD from the old one to the new one. Everything works well out of the box except that there’s something about the screen color that bugs me: it looks green, alien-ish(?). I’ve tried ways to fix it but I can’t seem to get any results. I found DisplayCAL but it seems to not work (or I just don’t know how it works properly) and I found DDCControl but it says the monitor doesn’t support DDC/CI. I’m no expert in screen colors so I’m pretty much stuck here. Any suggestions?

CPU: Intel i7-14650HX
GPU integrated: Intel Raptor Lake-S UHD Graphics
GPU Nvidia RTX 5060 Max-Q / Mobile
DE: Plasma 6.6.2
Session: Wayland
I’ll provide additional info if needed

Hi @y3550r ,
What GPU does your old laptop have?
How about checking the colors with a live USB?

I’m not an expert and can only suggest downloading some icc profiles.
gammas

icc
icc918×801 57.5 KB

OR try some icc profiles from
/usr/share/color/icc/colord/

  1. My old laptop’s GPU was an RTX 2050. I don’t think I’ve changed anything about drivers yet so idk if that could be a reason (likely not?)
  2. I’ve just tried doing that and for some weird reason, it didn’t change anything on the built-in screen. No matter which file I use, the screen stays the same. However, I tried it on my external monitor and it actually does something.

If it’s brand new, it could be faulty.

Quick update to my previous comment.

It actually works on the built-in screen. It was just very minor that I didn’t notice at first. I think I’ll look into making a custom ICC for this. Thanks

For DisplayCAL to work, you’ld need a colorimeter. And these are quite expensive. Without actual display measurements, you won’t be able to generate an icc profile.

It really depends on the make and model of your Hardware - and the actual display panel which your machine is equipped with. Most manufacturers would supply corresponding *.icc profiles. If you would provide us with that info on your machine, we could look it up for you.

Yeah, I recently just learnt about the colorimeter thing too. Currently, I’m in Plasma x11 manually adjusting my gamma but I’m not really good at coloring so it’ll probably take me a while. I would appreciate it if you can find the corresponding icc profile though. The laptop model is MSI Katana 15 HX B14W

I don’t see one available on the support site for that model on MSIs official website.

@y3550r ,
I copied sRGB-1.0G.icc from the above ‘gammas’ link as test.icc
and downloaded the following 2 zips.
https://www.color.org/profileinspector.xalter
Extracted zips
Installed wine
wine ICCProfileInspector
ran ICCviewer.exe in wine and was able to modify the icc file.
Modify the g(reen) component. Do not forget to save it.
It could be a long interactive procedure. (In case your goal is an approximative one)

Thanks, but luckily I’ve already managed to find a way to do it. Basically I created a file called gamma.cal and insert the following content:

CAL

DESCRIPTOR "Manual RGB gamma"

ORIGINATOR "manual"

DEVICE_CLASS DISPLAY

COLOR_REP RGB

NUMBER_OF_FIELDS 4
BEGIN_DATA_FORMAT
RGB_I RGB_R RGB_G RGB_B
END_DATA_FORMAT

NUMBER_OF_SETS 2
BEGIN_DATA
0.0 0.0 0.0 0.0
1.0 0.95 0.86 1.08
END_DATA

and then I went and downloaded an sRGB V2 ICC from here. Then I run the following command:

applycal gamma.cal sRGB-v2-magic.icc fixed.icc

This gives me fixed.icc which is the ICC I now use to fix the greenish screen.

From the sounds of it, I think you’re solution might be easier to work with so I’ll be looking into that in the future. Thanks again.
