Comment 8 for bug 1943816

Previous discussion was at https://chat.canonical.com/canonical/pl/1mgrhibwpj8ojxk89tbpztjdar. Due to the design of ubiquity, it only use ubuntu-driver to get package list and install package in 31ubuntu_driver_packages. But ubuntu-driver not only install packages but also create configurations of Nvidia GPU. This patch will copy configurations and calling prime-select to make sure it get same result as calling "ubuntu-driver install" directly.
