Soo..my nvidia 390 is not supported for the new kernel version
Just asking how to downgrade?
I looked online everywhere but i couldn't find a way to do that
You can use terminal with apt command and install the previous kernel you need.
For example, let's say you want the 6.5.0-41
sudo apt install linux-image-6.5.0-41-generic linux-headers-6.5.0-41-generic linux-modules-6.5.0-41-generic linux-modules-extra-6.5.0-41-generic
You can set it to default boot to prevent upgraded kernels from booting:
Okay so i want to install kernel 6.1.112 cause thats the last kernel thats support old nvidia gpus..what terminal command should i write ? I tried to change the numbers in the one u suggested but it didn't work
I must assume you are on Zorin OS 17.
Because 6.1.1.112 is not in the Repositories default on Z 17.
I looked in the Mainline PPA, and... it stops at -110...
https://kernel.ubuntu.com/mainline/
You can try the -110 but keep in mind - Secure Boot must be disabled in BIOS since these are unsigned:
https://kernel.ubuntu.com/mainline/v6.1.110/amd64/linux-headers-6.1.110-0601110_6.1.110-0601110.202409121041_all.deb
Assuming they save to your downloads folder, you can
cd ~/Downloads
sudo dpkg -i *.deb
to install all at once.
Once install, in terminal run
sudo update-grub
Reboot, then select the Advanced Options
from the Grub Menu. Select Zorin on 6.1.1.110
to boot into.
