Title: Laptop keyboard no longer working after system updates
Post by: giocip on September 03, 2020, 12:45:37 PM
Hi

I'm running LL 5.0 on a Packard Bell EasyNote laptop. I installed it about 2 months ago and have been running it without issues since then. There are no other OSs installed on this machine.

This morning the system notified me of available updates, which I installed immediately. I don't have a record of the updates in question. Once the update was completed, the system suggested I restart the laptop to complete the installation, which I did.

After restart, the laptop keyboard stopped working and I was unable to type my password to login. None of the keys worked. The touchpad was functional.

Eventually, I connected an external USB keyboard and was able to login using that. However, I've been unable to get the keyboard to work (restarted the laptop several times). The keyboard seems to work in grub/bios but never after that.

The keyboard is listed when running xinput list. Enabling/disabling the device in xinput makes no difference. The touchpad clicking mechanism works, but the cursor movement doesn't.

I'm at a loss as to what the problem might be. Any suggestions would be much appreciated.

Might have been a kernel updated. Revert back to an older one.

Thank you Jerry, that seems to have done the trick.

I was running 5.4.0-45, chose 5.4.0-42 in GRUB (not as easy as I hoped, GRUB wasn't showing on boot!) and the keyboard is working now.

Thanks for your help

My problem is, that I'm not able to "activat/write" all the keys like @, , [,  ], {, }, \    , etc.
Maybe you can help.

My Linux Lite: 5.0
System Locale: LANG=de_DE.UTF-8
       VC Keymap: n/a
      X11 Layout: de
       X11 Model: pc105

Thanks and best regards,
