Re: Ubuntu and HP Envy 17-3200
Sorry, but Switchable Graphics is not supported well in Linux. Those machines come with drivers (for MS Windows, of course) supplied by the machine vendors. Linux drivers are not available. If you try to install drivers from AMD, they won't work.
The link below is old, but it has some suggestions:
Ubuntu 16.10 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
