Ubuntu OS is not officially supported by LIVA MINI PC, but the latest Ubuntu 14.04 LTS is able to being installed into LIVA MINI PC. However, due to no official Ubuntu Driver provided by wireless card vendor, it is unable to support WiFi / Bluetooth function.

Due to Ubuntu security setup, LIVA MINI PC won’t boot up without monitor plugged in under Ubuntu OS. So we suggest you to connect the monitor when first booting up, during the system power on, hot plugging of the monitor is acceptable.
