Isn't this as easy as to put a GUI (Qt) that:
1.- runs sudo ubuntu-drivers list
2.- populate a list in which you chose the driver you want to install
3.- run sudo apt install "the driver you chose"
???
That sound to me easier than porting and if that is, I think I can take it.

Oh, and one more thing; systray functionality would be cool. On first startup (or maybe in the welcome center, @TheWendyPower?) it should start up and perhaps run a very minimal daemon.

Again, up to you though.

In 18.04 the application that makes this happen is software-properties-gtk and I found this code which has some qt mentions maybe it's very easy to compile this with qt https://bazaar.launchpad.net/~ubuntu-core-dev/software-properties/main/files @tsimonq2 @wxl

Right, it could be relatively simple to port it from PyGTK to PyQt.

I have commit and upload access to that package too, so I can just merge there if you wanted to do it in that menu.

I found out that we ship software-properties-qt (and software-properties-kde) but it doesn't have a menu entry. Although at the moment it doesn't have the "additional driver" tab, I think we should have the menu entry, people (and with that I mean myself) are used to use this instead of muon or synaptic for handle updates, repos, and the others.

software-properties-qt (and software-properties-kde)

software-properties-kde should no longer exist; I personally renamed everything to Qt.

Sure; maybe write a .desktop file and put it here? I can get it in the branch for you.

There is a .desktop file already in /usr/share/applications/software-properties-qt.desktop It is set to NoDisplay=true Perhaps if we changed it to OnlyShowIn=LXQt

and it doesn't have lxqt-sudo in Exec line. That edited should look like:
