So I have recently bought two identical monitor and I told the seller to calibrate both of them. The seller gave me 2 *.icm files. But it is impossible to import directly in dom0 as everything is greyed out and my monitor did not even detected in XFCE's Color Profiles GUI. After a bit of research, it turns out that I need to install a program called xiccd, but it is not available in Fedora 42 repo. So I decided to build the package myself using its original source. I do all of these in a dispVM, but if you're paranoid about the internet traffic, just set firewall rules because this script needs access to github to grab the source files of xiccd and some dependencies needs to be installed from the repo. But firstly please bear with me if you find any error in this script, I stole this script from David King's github and modified a little bit.

Create ~/rpmbuild directory to place these scripts

Create mkrpms.sh file and make it executable (chmod +x mkrpms.sh)

mkrpms.sh

#!/usr/bin/env bash

SPECFILE="xiccd.spec"

set -e

# Get the full path to the spec file
SPECFILE=$(dirname "$(realpath "$0")")/$SPECFILE
MY_HOME=/home/$(env | grep SUDO_USER | sed 's/SUDO_USER=//g')

# Parse the package name, version and release out of the spec file
NAME=$(sed -n 's/^Name:[[:space:]]*//p' "$SPECFILE")
VERSION=$(sed -n 's/^Version:[[:space:]]*//p' "$SPECFILE")
RELEASE=$(sed -n 's/^Release:[[:space:]]*//;s/%{?dist}//p' "$SPECFILE")
ARCH=$(sed -n 's/^BuildArch:[[:space:]]*//p' "$SPECFILE")

# Create output directory 
mkdir -p ${MY_HOME}/rpmbuild/RPMS/${ARCH}/
mkdir -p ${MY_HOME}/rpmbuild/SRPMS/

echo -e "\nUpdating system software and installing required dependencies ..."
dnf -y upgrade
dnf -y install wget gcc-c++ make autoconf automake libX11-devel libXrandr-devel glib2-devel colord-devel rpm-build

# Get the source file
SOURCE0=$(sed -n 's/^Source0:[[:space:]]*//p' "$SPECFILE")
SOURCE0=$(echo "$SOURCE0" | sed "s/%{name}/${NAME}/;s/%{version}/${VERSION}/")
wget -O "${HOME}/rpmbuild/SOURCES/${SOURCE0}" "https://github.com/agalakhov/xiccd/archive/v${VERSION}.tar.gz"

# Build the packages.  Try twice, in case of an Access Exception, which happens occasionally
if ! rpmbuild -ba "$SPECFILE"; then
    echo -e "\nrpmbuild failed, retrying rpmbuild ..."
    rpmbuild -ba "$SPECFILE"
fi

echo -e "\nCopying RPM files to host system ..."
mv ${HOME}/rpmbuild/RPMS/${ARCH}/${NAME}-${VERSION}-${RELEASE}.*.${ARCH}.rpm ${MY_HOME}/rpmbuild/RPMS/${ARCH}/
mv ${HOME}/rpmbuild/SRPMS/${NAME}-${VERSION}-${RELEASE}.*.src.rpm ${MY_HOME}/rpmbuild/SRPMS/
echo -e " OK!"

Create xiccd.spec with the following contents xiccd.spec

%description
xiccd is a simple bridge between colord and X. It is used to enable the 
xfce4-color-settings tool in the XFCE desktop.  This allows for simple 
configuration of the color profiles that the colord daemon loads for 
displays attached to these systems.

    Initial Version
* Fri Feb 28 2020 David King <dave@daveking.com> - 0.3.0-2
    Correct placement of xiccd.desktop

Finally lets build it sudo ./mkrpms.sh

If everything went fine, you should have an *.rpm file in ~/rpmbuild/RPMS/x86_64/xiccd.blah.blah.rpm

Then move it to dom0 and install it sudo rpm -Uvh xiccd.blah.blah.rpm

To check if it successfully installed run xiccd -V

Reboot and you should see both of your monitors are detected in dom0's Color Profiles GUI

Now you should be able to import and apply these calibration files .icc/.icm

Ferdinand Heinrich in Qubes Chat for the idea of building from source

David King for the original script that I stole

It would be a pleasure if anyone care enough to correct my bash script mod and host it to github or somewhere as I dont have github
