Fix at bottom comment.
Installed Linux Mint Cinnamon 18.3, installation went fine.
However, I'm stuck on the native 1024x768 resolution with nothing in the resolutions bar besides it.
my processor is Ryzen 3 2200G RX Vega 8. In the AMD website the only drivers are for Windows 10, and installing past RX Vega drivers doesn't sound very well.
I searched in the forum and saw allot of either Nvidia\ Intel issues or past AMD issues.
I'm plugged with VGA on both ends, and xrandr showed this:
