I've just made a fresh install of Ubuntu 18.10 Cosmic on a brand-new Lenovo Yoga C930. The installation went super-fast, but in the end there was no WiFi.

$ uname -a

Turns out that I had to blacklist the kernel module "ideapad_laptop" to make everything work just fine. Several sources report this online, e.g. [¹]. I've been told on IRC #ubuntu that there's an alternative approach to get this fixed w/o blacklisting, see [²].

Other Lenovo Yoga models seem to be affected likewise, e.g. the C920. According to user jeremy31 on IRC this issue has existed for a few years, and a user ryuo wrote the code he provides as a fix on GitHub.

Can this be fixed upstream to make a fresh installation "just work" out of the box?
