Armbian as well?

Hi Igor, Armbian is working well. But I really want to Ubuntu. (I am totally noob here, just guessing; maybe in Armbian the gpu support is not working?! Because is extremely slow)

Same here. Maybe the something wrong with the refresh rate, because my monitor keep notifying me with that: 'out of range' Any suggestion?
