Linux on MacBook Air with NVIDIA drivers

In order to use the proprietary NVIDIA driver on a MacBook Air 3,1 (11-inch, late 2010) with the NVIDIA GeForce 320M chipset booting openSUSE Leap 42.1 in EFI mode, create the file /etc/grub.d/01_enable_vga.conf with the following content:

#!/bin/sh
set -e

# Initialize the PCI-E registers of MBA 3,1 for the nvidia driver

cat << EOF
btrfs-mount-subvol /dev/sda3 /boot/grub2/x86_64-efi /@/boot/grub2/x86_64-efi
insmod setpci
setpci -s "00:17.0" 3e.b=8
setpci -s "02:00.0" 04.b=7
EOF

and run grub2-mkconfig -o /boot/grub2/grub.cfg to update the bootloader configuration. Be aware that you might need to determine the PCI bus ids for your machine first by running lshw -businfo -class bridge -class display as described in this post on askubuntu. (Please note that using only the setpci command as suggested in that post for Ubuntu systems does not suffice on openSUSE systems, because on this system the setpci functionality is provided as a separate GRUB module and must be loaded explicitly with the insmod command; since the GRUB modules are not installed on the boot partition, their location has to be mounted first using the btrfs-mount-subvol command.)

Reboot and verify that the settings have actually been applied by running the setpci command on the command line as root without the part after the equal sign (e.g. setpci -s "00:17.0" 3e.b). This should return the values assigned before, i.e. 8 or 7 respectively.

Then proceed installing the nvidia driver by choosing the appropriate package on the openSUSE Community website. In my case (NVIDIA GeForce 320M), that means choosing the „Geforce 8 series and later“ option.
