maybe disable nouveau in /etc/modprobe.d . i think if your nvidia was
installed correctly you would have a conf in that directory that
blacklists the nouveau driver. i would also check /lib/modules/ to see
if there is even annvidia.ko module there. my guess is that your nvidia
package is not installing. try a sudo modprobe nvidia and see what the
result is.
i have not used ubuntu for a long time so someone else can probable
help you with getting the ubuntu nvidia packageinstalled. you may want
to read the arch wiki on nvidia as it has a lot of good tips for
running their driver.
