You first should care about error messages and ignore warnings, if
they should be unclear. Use Google or Startpage, avoid DuckDuck and
similar and use the error messages as search terms.

Regarding errors, care first about "fatal" errors.

E.g.

Did you already made some Internet research on your own and if so,
what did you find?

ubuntu-mate at ubuntu-mate:~$ man apt | grep full-upgrade -A1 | tail -3
       full-upgrade (apt-get(8))
           full-upgrade performs the function of upgrade but will remove currently
           installed packages if this is needed to upgrade the system as a whole.

I don't know software-updater, but apt full-upgrade, resp. apt-get
dist-upgrade is what Synaptic calls a "smart" upgrade and it's the
recommended way to upgrade.

"client has the version 304.132, but this kernel module has the
version 304.131. Please make sure that this kernel module and all
NVIDIA driver components have the same version."

This definitively needs to be fixed.

I like the advantages of a xorg.conf.

ubuntu-mate at ubuntu-mate:~$ grep Driver /media/moonstudio/etc/X11/xorg.conf
        Driver   "radeon"
       #Driver   "vesa"

As a fallback I always could switch to vesa.

However, it might not be the only culprit, but you anyway need to fix
the driver issue.

Simply install the proprietary NVIDIA driver you used before, or
consider to switch to the nouveau driver and also consider to finmd out
why there is this version inconsistency.

Try running

sudo apt-get purge nvidia-current
sudo apt-get install nvidia-current
