Getting the same color settings on Linux as on Windows

Software & Operating Systems Linux

So a few days ago I finally took the plunge and installed Pop_OS! on my main desktop (Nvidia graphics). So far I have been enjoying it a lot. But there’s this one thing for which I can’t find a solution.

Under Linux the colors of my display (Dell U2412M) look like shit. Everything is too blueish and whites are blown out compared to Windows.
I would like to have the same calibration under Linux as I have under Windows.

For some reason GNOME settings doesn’t want to load my Windows color profile (tried .icc and .icm files). I end up getting the message “missing information for whole screen correction”. The color profile doesn’t seem to affect my settings whatsoever.

I have been searching all day for a solution and have also tried using colormgr in the terminal, but all to no avail.

Would someone be willing to help me? I just want the same colors under Linux as on Windows. How can one accomplish this? What’s the solution or is there another way?

Wow, I didn’t realise you can do this in the Gnome settings.

I only ever used the settings on the actual monitor, with buttons and my finger, like some simpleton caveman.

Now I see the menu item, I have 3 automatic profiles listed, none of which I can change.

Well, At least it kinda exists?

Is Pop! Using wayland or xorg? Might try to switch’em

I’ve been able to load my display color profile no problem on gnome’s display sertings. However I didn’t create it from Windows. Windows accepts the same file and both OS’s boot with my custom profile. Maybe your profile’s format is the problem?

So gnome settings doesn’t like to load a profile that’s not installed via the command line for some reason.

Here’s the process I like to do. Using root permissions either in the command line (sudo) or GUI (gksudo) or better yet (filemanger command alias) admin:///path … Move your profiles to the following folder: usr/share/color/icc

Then gksudo open your gnome-color-manager. That often fixes it

Also welcome back bmsk

So I followed all suggestions. There was indeed something wrong with the colour profile that originated from Windows. Linux wasn’t able to read it correctly. To fix this I created a new colour profile using my Mac (I know what a workaround).
Gnome settings was able to read this new icc profile without issues, but didn’t apply it.

Gnome-color-manager seems to not be installed on Pop and even after installing the package it can’t be opened (weird right?). So I ran the following colormanager commands as root:

colormgr get-devices-by-kind display (looking up device ID)

colormgr find-profile-by-filename /var/lib/colord/icc/<name of the icc file> (looking up profile ID)

Make the new profile default:

colormgr device-add-profile <display id> <profile id>
colormgr device-make-profile-default <display id> <profile id>

And for some weird reason that did the trick! After a reboot the right colour profile was installed persistently. I thought I would leave this here in case someone else ever needs it.

Thanks for the update!

[Welp, not fixed, a work around was found. Oh well!]

I don’t have a mac available. How can I create a icc file from a vendor based icm file for Windows?

weird thought, make a color profile in l i n u x

I tried to do that but gnome requires special calibration hardware to be connected?

Oh do you do photo work?

The reason I say this is that there is a settings menu for color space that you can go through. Its not like on windows at all.

Gnome doesn’t allow me to calibrate the screen.

If you go to settings > devices > display, you can set stuff like sRGB or Adobe 1994/8 color spaces was my point.
