I am running crazy trying to install Slic3r on my Kubuntu 14.04. It is a fresh Kubuntu and I downloaded the Slic3r package from them.
At first it worked well but then I changed the display driver to NVIDIA instead of the default Nouveau. I have repeated this operation a couple of times and I am almost sure that the NVIDIA driver screws up my system.
I have read and followed several "SOLVED" posts but none of them gave me a solution.
