Can't get Zorin OS 18 installed

I looked for Your GeForce 210 Card and it seems that it would need the Driver 340 which is a pretty olde one and not available in the Repo's. But there is a PPA what offers the Driver for newer Kernels.

So, I would suggest the following Way:

  1. Install the 6.8 Kernel from the Repos
  2. Add the PPA to install the 340 Driver for Your Card

So, first install the 6.8 Kernel with the Command:

sudo apt install linux-headers-6.8.0-124-generic linux-image-6.8.0-124-generic linux-modules-6.8.0-124-generic linux-modules-extra-6.8.0-124-generic

When installed, reboot and on the GRUB Menu choose ''Additional Options'' and there choose this Kernel (without the Recovery Option). When booted and loged in, type in Terminal uname -r to check that You really in this Kernel. To set that Kernel as default, follow these Instructions:

Then add the PPA with

sudo add-apt-repository ppa:kelebek333/nvidia-test

and then make a sudo apt update to refresh the Sources. To install the Driver type

sudo apt install nvidia-graphics-drivers-legacy-340xx

But when You are find with the Nouveau Driver, of Course, You don't have to do that all. Then ignore it.
