I can't Activate NVIDIA Graphics Card( i using GT 730 4GB)

[Forpli]

For nvidia driver 390 you need a ppa from kelebek333 or kernel 5.15 to install them. Kernel 6.8 Zorin 17 uses doesn't support nvidia 390 driver.

First method: add ppa from kelebek

To remove installed nvidia drivers enter in terminal

"sudo apt-get remove --purge '^nvidia-.*'"

Then add the kelebek repo:

"sudo add-apt-repository ppa:kelebek333/nvidia-legacy"

Install the driver:

"sudo apt update &&
sudo apt install nvidia-driver-390 nvidia-dkms-390"

(you can also enable the driver package from nvidia 390 driver at Software & Updates>additional drivers)

Second alternative method:
Install the 5.15 kernel

"sudo apt install linux-headers-5.15.0-141-generic linux-image-5.15.0-141-generic linux-modules-5.15.0-141-generic linux-modules-extra-5.15.0-141-generic"

Then reboot into this kernel (choose advanced options at grub menu when booting and search kernel 5.15 there).

Set this kernel as default:

[HOW TO] set an older kernel to default boot

You may need to use an earlier kernel than the current kernel used by Zorin. This method allows you to set the kernel that you will boot into by default. To set the new kernel to default: Boot into the kernel you wish to be Saved. Open terminal and run: sudo nano /etc/default/grub Change GRUB_DEFAULT=0 to GRUB_DEFAULT=saved Hit enter to drop down a line. Add GRUB_SAVEDEFAULT=true ctrl+x to exit, then the y key to say yes to save, then the enter key to save as current configuration. Ru…

Now remove your old nvidia drivers
"sudo apt-get remove --purge '^nvidia-.*'"

Then install the driver 390:
"sudo apt update &&
sudo apt install nvidia-driver-390 nvidia-dkms-390"

Reboot.
