xcalib is not working on ubuntu 14.04

Solution 1:

I solved that problem by installing the newest version of xcalib, as detailed here:

Firstly, you need to have git, make, cmake, and some libraries:

sudo apt install git cmake make libx11-dev libxrandr-dev libxxf86vm-dev

Then do:

git clone https://github.com/OpenICC/xcalib.git
cd xcalib
cmake CMakeLists.txt
sudo make install

That works even if you do not get an error message. It works on Ubuntu 19.10 and 18.04. Also with Unity desktop manager.
