Hi all! I've recently acquired an old imac and put zorin core 16.2 on it, but for some reason I cannot get the nvidia propriety driver to work!
I have followed some of the advice on other threads but as I have an imac not all of the advice is relevant.
OS: Zorin OS 16.2 64-bit
iMac, late 2012, serial number C17JT03ZDNCR
memory: 7.7 GiB
Processor: Intel Core i5-3335S CPU @ 2.70GHz x 4
Graphics: NVE7 (was llvmpipe (LLVM 12.0.0, 256 bits at one point too)
disk capacity: 1 TB
windowing system: X11
Kernel info - 5.15.0-71 - generic #78~20.04.01-Ubuntu SMP Wed Apr 19 11:26:48 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Currently on X.Org X Server -- Noveau display driver from xserver-xorg-video-noveau. The whole screen freezes sometimes when a tad bit more cpu is used e.g watching a video. Playing aqueducts is very slow and tuxxkart not loading!
The additional drivers tab says I have a GKM107M (GeForce GT 640M Mac edition)
Tried to use NVIDIA binary driver - version 340.108 from nivdia-340 (proprietary, tested) but came up with an error message:
"pk-client-error-quark: error while installing package: installed nvidia-340 package post-installation script subprocess returned error exit status 10 (313)"
I have tried to follow the general advice on nvidia drivers (Activate NVIDIA Graphics Card - Zorin Help) but none of the solutions work. I seem to have no BIOS menu available (only options are run zorin and advanced menu). In any case this mac has no secure boot.
I tried to install using the "install with modern nvidia" just to see if it would work, but had to do a partial upgrade, and resulted in the graphics card being a "manually installed one" called LLVMPIPE.
I then tried installing dkms, but this crashed the system with the "oh no! something has gone wrong" white screen. I then uninstalled the DKMS, which seemed to work but then crashed again when I tried to run it again on the nvidia driver, so I reinstalled the whole OS.
Any ideas on how to get it to work? Ideally I would like to 1 - get the nvidia drivers to work, and 2 - perhaps download a more newer driver if it works.
I'm starting to wonder though if the mac is too old now to have the most recent nvidia driver installed. I could try and follow the manual installation tutorial but don't I also need dkms to not lose progress on next upgrade? Or perhaps dkms should be installed only after you have a working nvidia driver?
I have some IT knowledge, but I am a rookie when it comes to using terminal!
I also have a zorin 16.2 on a hp pavilion laptop, works like a dream! Pity macs seem so problematic...
