Really dumb/basic problem here :-) Hoping someone with the same experience can help!
I'm trying to install openSUSE (Leap 16.0) on my 2018 MacBook Air, using an iso flashed to a USB stick.
The built-in keyboard/trackpad works at the first stage of the install (I guess it's the Grub screen?) where I can choose between Boot from main drive, install, safe-mode install, UEFI firmware settings, etc.
Choosing "install" or the safe-mode install gets me as far as a screen with two radio buttons, where I have to choose between Leap 16.0 and Leap Micro 6.2.
At this point, the built-in keyboard/trackpad no longer works.
My ?standard Lenovo USB keyboard, plugged into either of the two USB ports, doesn't work (no response, NumLock key doesn't light up, etc.).
Has anyone been through a similar experience? Seems really weird that the built-in keyboard works at the first stage but not the second!
Is it worth trying a bunch of other USB keyboards in case there's something non-standard about my (very basic!) Lenovo keyboard? Or do I have to do something like add a driver for the built-in keyboard before flashing the installer?
Thanks!
