Intel GMA 3600
The Intel GMA 3600 series is a family of integrated video adapters based on the PowerVR SGX 545 graphics core. It is used in Intel Cedarview CPUs (Atom D2500, D2550, D2700, N2600 and N2800).
The Linux kernel has support since version 3.5, but since version 4.15 the relevant kernel driver, uvesafb, has not been included in the Archlinux kernel so using the DKMS version of the driver is necessary. See uvesafb for more information.
At the moment there is no accelerated driver for Xorg Server, but some support is available using the Xorg modesetting driver provided by package.

The following can be used to disable LVDS and force enable VGA if needed.

Blank screen after resume
If after resume you got a blank screen try the following
# touch /etc/pm/sleep.d/99video
It is unable to utilize whole chip power and play fullHD movies using graphics acceleration. As workaround you could utilize the maximum power of your Atom CPU to decode video:
mplayer -lavdopts threads=4 -fs myvideo.avi
mpv vd-lavc-threads=4 -fs myvideo.avi
