Late 2010/early 2011 Macbook Air 3-2, Narwhal or Meerkat presumably (model A1369) / Ubuntu 20.04 / No OS X. I wiped the disk when installing Ubuntu
Installation from live USB stick. On first attempt, I chose the option to install third party hardware drivers, including the Nvidia driver.
On reboot, the screen would show the below message twice, then go black, with no apparent way to recover the situation. In other words, for all practical purposes, the installation failed.
Failed to set MokListRT: Invalid Parameter
Could not create MokListRT: Invalid Parameter
Importing MOK states has failed: import_mok_state() failed
: Invalid Parameter
Continuing boot since secure mode is disabled_
The error message above appears to relate to a problem with the shim bootloader not playing nice with older Macbook Airs, according to this:
Someone on the above linked page mentioned the Nvidia driver packages possibly also being involved in this, so I attempted a fresh installation, this time not using the Nvidia prop drivers.
This time, on reboot the above error message only appears once and then Ubuntu starts up and I’m able to log in. So the Nvidia drivers are the bigger issue here, that error message seems inconsequential.
Unfortunately, the open source drivers for the nvidia card perform poorly with video so I'd really like to install the prop ones.
So two questions.
- How to fix the graphics driver issue?
- How to fix the error message at boot?
Any help appreciated!
