Just updated to Linux x8e 4.4.0-112-generic #135-Ubuntu and the same problem previously described has reappeared. Before the update to this kernel, I was running 4.4.0-109-generic. Since I installed ubuntu 16.04 LTS MATE the F8 and F9 keys adjusted the brightness. Now they do nothing. The laptop is a rebranded Clevo by Eurocom and is an Extreme X8E.
