Able to access the POST, UEFI and boot into Lubuntu installation.
However, after installation completion, it reboot to a no video output.
Keyboard NUMLOCK light on, board is connect my house router network.
Any suggestion?
Have been emailing support but never receive a respond ever.

Hi Sir,

We never tested Lubuntu, but Ubuntu desktop/server 14.04.1, debian 8 have tested and working fine.
Maybe you can try Debian to check if it is working or not.

BTW, ubuntu with Xwindows is not working smoothly, freezing a lot because lack of RMA, so i suggest debian 8 with desktop, it is working very good.
