Correct.

Oh.  More updates needed.

cirrus is modesetting too, unless you use a *really* old distro.

qxl is on a similar path.  In case xorg-x11-drv-qxl.rpm is installed
xorg will prefer the qxl driver.  In case the driver is not present xorg
will use the modesetting driver instead and it'll work equally fine.
I think RHEL-9 doesn't ship xorg-x11-drv-qxl.rpm any more.

virtio-gpu will also be handled by the modesetting driver.

So possibly you can just do 'let video_driver = "modesetting"'

take care & HTH,
  Gerd
