Title:
Kernel module "ideapad_laptop" kills WiFi on Lenovo Yoga C930 (18.10
Cosmic)
Status in linux package in Ubuntu:
Incomplete
Bug description:
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
Linux roma 4.18.0-10-generic #11-Ubuntu SMP Thu Oct 11 15:13:55 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux
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?
