I think the Sun Blade has a frame buffer. Could you see what is in

If it doesn’t contain the following lines, then I would recommend adding them:


This will prevent the frame buffer from being used and forces it to use the
console. It will also preload the iso9660 module, which helps cover up some
known bugs that need to be fixed.

Afterwards you will need to regenerate your grub.cfg, with the grub-mkconfig
command. See if this helps with the arrow keys.

I’m not used to being on this older hardware.<...
