This output suggests only that Xorg is using the nouveau DDX. To switch to the
modesetting DIX, which is the actual upstream default, and not a discrete package,
removing the nouveau is the easy way:

	sudo apt purge xserver-xorg-video-nouveau

Alternatively, you can create a config file in /etc/X11/xorg.con* to specify use
of modesetting instead of nouveau.

Looks like you are using the broken ancient inxi that came with 18.04 that is
incapable of reporting the loaded kernel graphics driver, and a lot of other
things a recent version can. Before trying to use it again you should purge it,
and install the upstream version, if you wish good information from it:
