I used this info to change the size and font at boot. Maybe it'll help you
too.

You should be able to use the below command to find out which version is
installed. Example below from my workstation.

sorin at lanfear2:~$ dpkg -l |grep nvidia-driver | grep ii
ii  nvidia-driver-550                             550.90.07-0ubuntu0.22.04.1
amd64NVIDIA driver metapackage

Not sure either. Finding out which driver package is active as outlined
above is a start I think.

No other driver package för nvidia should be installed I guess.
An "apt autoremove" should remove anything that is not needed anymore.

Note, when you run "apt-cache search nvidia" it shows you what is available
to be installed, not what is installed AFAIK.
