My fresh installation of Kali has been crashing after logging in and moving the cursor over any icons on the desktop, some minor artifacts show and the screen turns black/off. I suspect this to be a problem with my AMD R9 390 GPU, now I want to disable the AMD drivers so I can boot Kali using the Integrated Intel Graphics (Intel 6700k).

I've found the code for Nvidia drivers, thanks to the following thread:

apt-get remove --purge nvidia*
rm -rf /etc/X11/xorg.conf

rm -rf /usr/share/gdm/greeter/autostart/optimus.desktop
rm -rf /etc/xdg/autostart/optimus.desktop

Now I'm wondering how I can reach the same outcome for a AMD GPU.
