You should show us your inxi -F and your Driver Manager screen.

Your OS kinda sounds like LM213.

I tried LM223 in a fresh install, and it is offering
me the 580 driver only, for a GT1030 video card.

Some other release, I was seeing the Driver Manager telling
me that "you already have the best driver and no drivers are
available for your setup". And one way to fix that, is to
remove the 580 packages from the tree, then after a reboot,
the Driver Manager works again and legacy drivers are listed.

It would be good if you'd indicate your OS revision, like
if you aren't "current" right now.
