Hello

So when I had first gotten the laptop, the first thing I did was to delete Windows 10 and install Ubuntu 16.04. At first, everything worked fine. But after a while the trackpoint, touchpad, additional click buttons became buggy. Some worked some not, inconsistently. And after a time, only the touchpad started working. The rest seem dead now. So, is there a way to solve this issue? Ubuntu does not seem to recognize the trackpoint and other additional mouse buttons above the touchpad.

Thanks!
