Xorg failed to load Intel driver for Axiomtek MANO300 which is based on Intel Braswell N3160

[Rex Tsai]

The Mini-ITX SBC platform[1] is using Intel N3160 Processor with Integrated Graphics Controller. However, the xorg failed to load the Intel driver as autoconfigured driver. It fallback to using fb and glamoregl for 2D acceleration method, which caused some issues[2] in multi-screen mode,
including mouse cursor to get corrupted, or leave copies of cursor around.

The issue can be reproduced on 17.04, 17.10. (and most likely on 16.04).

The workaround for the issue is to install a xorg.conf to force xorg load the Intel driver, which solved the issue.

Workaround:
Please write the following content into /usr/share/X11/xorg.conf.d/90-intel.conf (without dash)
