My new laptop came with Intel Core i5-1035G4 processor. I have installed Ubuntu 18.04.3. It has only one resolution in the display menu and the brightness controls are missing. This is most probably due to the graphics drivers but I can't seem to find graphics drivers for Ubuntu.
Does anyone know how I can update the graphics drivers?
