You have been subscribed to a public bug: After working perfectly for over a year the touchpad and wifi on my HUAWEI MateBook X Pro 2020 (MACHC-WAE9LP) suddenly stopped working (no response at all from touchpad).
``cat proc/version`` gives: Linux version 5.13.0-21-generic (buildd@lgw01-amd64-043) (gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #21-20.04.1-Ubuntu SMP Tue Oct 26 15:49:20 UTC 2021 This problem first occured the 6. of December, after not using ubuntu for a couple of days (I have both windows and ubuntu in dual boot). Both the touchpad and wifi works fine in windows. When following the instructions on https://wiki.ubuntu.com/DebuggingTouchpadDetection#generalinfo, I found that ``cat /proc/bus/input/devices`` does not include a touchpad. According to the wiki this is because the kernel fails to recognize the touchpad. I also noticed some status messages printed to the screen during booting, which has not been the case before the problem occured. It consists of a lot of these messages: | OK | Started ...some process... | OK | Finished ...some process... And ends with: /dev/nvme0n1p2: clean: 1300006/38523392 files, 18658438/122878312 blocks I have not done much research on the wifi issue yet. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- Kernel fails to recognize touchpad, also no wifi https://bugs.launchpad.net/bugs/1955760 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
