    Broken Driver Manager

    Upon logging into the Driver Manager under System Settings and attempting to change the driver (say to the Nouveau driver), the response is:
    See the graphic - can't copy text from this terminal window.

    The Additional Drivers tab says the recommended driver is being used (correct) and the radio button is on for the Nvidia 470 driver, but the Apply Changes button is grayed out.

    I can switch between Nvidia 470 and Nouveau with no problems using the terminal. Both drivers work fine.

    There seem to be broken connections in the Driver Manager, but I have no idea on how to fix.​
