Installation Instructions (Linux)

Although, there are currently no RPM, DEB or other common packages to install DisplayCAL directly under Linux, some distros supply recent DisplayCAL versions in their package management systems. Please search for them first.

Otherwise you can install DisplayCAL under Linux pretty easily.

Prerequisites

In Linux, you can install DisplayCAL into a virtual environment through PyPI or build it from source. Currently we support Python 3.9 to Python 3.14.

To install DisplayCAL there are some prerequisites:

  • Assorted C/C++ builder tools
  • dbus
  • glib 2.0 or glibc
  • gtk-3
  • libXxf86vm
  • pkg-config
  • python3-devel

Please install these from your package manager.

# Debian installs
apt-get install build-essential dbus libglib2.0-dev pkg-config libgtk-3-dev libxxf86vm-dev python3-dev python3-venv

# Fedora core installs
dnf install gcc glibc-devel dbus pkgconf gtk3-devel libXxf86vm-devel python3-devel python3-virtualenv

Note

Note, if your system's default python is outside the supported range you will need to install a supported version and its related devel package.

Install through PyPI

Installing through PyPI is straight forward. We highly suggest using a virtual environment and not installing it to the system python:

Create a virtual environment:

cd ~
python -m venv venv-displaycal
source venv-displaycal/bin/activate
pip install displaycal

and now you can basically run displaycal:

displaycal

If you close the current terminal and run a new one, you need to activate the virtual environment before calling displaycal:

source ~/venv-displaycal/bin/activate
displaycal

Build From Source (Makefile Workflow)

To test the latest code you can build DisplayCAL from its source. To do that:

Pull the source:

cd ~
git clone https://github.com/eoyilmaz/displaycal-py3
cd ./displaycal-py3/

At this stage you may want to switch to the develop branch to test some new features or possibly fixed issues over the main branch.

git checkout develop

Then you can build and install DisplayCAL using:

make venv build install

The build step assumes your system has a python3 binary available that is within the correct range. If your system python3 is not supported and you installed a new one, you can try passing it to the build command:

$ SYSTEM_PYTHON=python3.11 make venv build install

If this errors out for you, you can follow the Build From Source (Manual) section below.

Otherwise, this should install DisplayCAL. To run the UI:

make launch

Build From Source (Manual)

If the makefile workflow doesn't work for you for some reason, you can setup the virtual environment manually. Ensure the python binary you're using is supported:

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt -r requirements-dev.txt
python -m build
pip install dist/displaycal-*.whl

This should install DisplayCAL. To run the UI:

displaycal
