Yesterday I installed Zorin Core on my Macbook Pro 15" late 2008 hoping for a better experience. The computer has 8gb of ram, 256gb harddrive and a NVIDIA GeForce 9600M GT graphics card.
When I installed Zorin I had 3 options:
Option 1: "Try or Install Zorin OS". Result: gray screen after reboot.
Option 2: "Install Zorin OS (safe graphics). Result: gray screen after reboot.
Option 3: "Install Zorin OS (modern NVIDIA drivers)" which didn't feel right since it is supposed to be for computers with NVidia graphics from 2013 and so on.
However the third install actually worked BUT the graphics are painfully slow. And the computer now feels slower than it was with the old Mac OS 10.11.6.
Is there some obvious fix or should I just go back to MacOS?
Have you looked at Zorin>Settings>Software and Updates>Additional Drivers ?
Which driver do you have and what options are listed?
Another thought.
From the user login screen, click on the login field and a gearwheel icon should be seen on the screen. Click on that and see if you are using Wayland or Xorg option.
I think the issue is down to nvidia closed source drivers would need to be an early driver iteration. The problem with this is that they become deprecated with newer linux kernels, meaning they won't work. I would be curious to see if you had any better luck with Q4OS KDE as I managed to install this on a rig I built in 2006 which has a single core Athlon 64 AMD processor, 2 Gb RAM and an EVGA nvidia chipped graphics card of 512 Mb 8x AGP!
