So I just updated to 16.10 (just got 16.04 a few weeks ago, still new to Linux). The keyboard still works when I need to enter my password to unencrypt the lvm drive, but stops working (along with the mouse) when I get to the login screen. Is this a known problem? How do I fix this?
By the way this is installed on a lenovo think pad.Thanks
Edit: got home and tried connecting a usb keyboard. Does not work (again only after reaching the login screen) . What on earth is going on?
Answer
I had the same issue today and found this bug report.
The problem seems to be, that during update process they forget to install/update the package xserver-xorg-input-all
!
So these instructions worked for me on my thinkpad p51s notebook with a little modification:
- Press a Shift key during boot to get the GRUB menu.
- In GRUB, select Advanced Options, then the first kernel with the recovery mode.
- Select “Network” to get network access (needed for package installation)
- Select “Drop to root shell”
- Press Enter to confirm.
- On my system not needed because, the filesystem was mounted rw, but if needed then
mount -o rw,remount /
. - Install the needed package:
apt install xserver-xorg-input-all
(and the message that they need to uninstall 16.04 packages!) - Press Ctrl+D to leave the root shell.
- Select resume boot from the menu.
- Now I could only log into console.
sudo reboot
After reboot my ThinkPad’s mouse and keyboard and the external mouse and keyboard worked fine!
