@jarkko Some Lenovo laptops offer Fedora as a preload option. If there is one that you want or bought that doesn't, then please give feedback to let them know you want Fedora there too! 😃
@jarkko
Ubuntu and Fedora are the two Lenovo's vendor supported Linux distros they have, but Ubuntu is available on more models.
It's not a bad idea to keep the pre installed option in a small partition, it has special engineering done to get the model certifiedand it's good to use as a reference of "is this a hw or sw issue" when using something else instead. And you might get something useful out of it like fingerprint driver blobs to your main OS.
@jarkko
In case of the fingerprint reader example, kernel drivers are open but in at least one 3y+ case there's a libfprint (which is open source) library plugin for interacting. I'd hope more recent fingerprint devices would be better.

I prefer fingerprint to typing my password in a cafe, but sure there are better options as well.
