Mint Intel Driver Config
<code>
sudo apt-get remove xserver-xorg-video-intel
sudo reboot
</code>

confirm with 
<code>inxi -G</code>
and 
<code>grep modesetting /var/log/Xorg.0.log</code>


To revert to Intel driver:
<code>
sudo apt-get install xserver-xorg-video-intel
sudo reboot
</code>

X 2D performance better on Intel driver vs modesetting with optimised SNA (as opposed to generic GLAMOR)
