I have a 2008 Unibody Macbook Pro that I have installed EndeavourOS(Arch based distro), which I tried to install nvidia drivers on and when I did the screen colors became inverted. This model has two nvidia gpus one being a GeForce 9400M and the other is a GeForce 9600M GT. the driver used was nvidia-340xx installed from the AUR. I understand that this driver is no longer supported, but stupidly decided to install it figuring it would help the system better utilize the weird dual gpus these C2D Macs had. If anyone has any idea on how to revert the screen back to displaying normal colors after the fact that would be great. Also, while most of the screen is inverted some things such as terminal windows and parts of other application windows are the correct color so I can't do a simple invert at all.
