fresh installed just yesterday, everything works except brightness and audio button which I already manually fixed.
after the 199 updates from "Menu-Control Menu-Software-Check & Install Updates" and rebooted, and.....the touchpad is dead right away, no sign of life. I still can use CTRL+ESC to bring up the menu if I wish but luckily the mouse works.

here's my inxi output:
