[Kernel-packages] [Bug 1815312] Re: Kernel module "ideapad_laptop" kills WiFi on Lenovo Yoga C930 (18.10 Cosmic)
apport information ** Tags added: apport-collected ** Description changed: 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?
