I have recently installed Ubuntu 20.04 on my Toshiba Satellite L50-A-18T laptop and everything went smoothly except when I noticed that neither the keyboard nor the track pad worked, only external keyboards and mouses. I have tried to look for a solution but no luck. This only happens when I boot into Ubuntu, if I boot into windows the keyboard and track pad work fine.

Using a chuwi aerobook, had the same problem, tried most of the available solutions online and patches to no effect. I then reinstalled 20.4 to find keyboard stopped working again after half day.

As it turns out, after recovery mode boot, keyboard / track-pad work again, although lost control of screen brightness. :)

Waiting for a more 'permanent' solution.

  • Did you found a solution ? – Nicolas Nov 23 '20 at 09:17
  • Yeah, it's working. I boot to GRUB and select previous kernel version rather than default.

    Go to GNU GRUBfrom There if i select 'advanced options' instead of the default and boot from Linux 5.4.0-42-generic i have access to all keyboard and trackpad features. There may be more permanent solutions.

  • For me the solution was: echo 'blacklist intel_vbtn' >> /etc/modprobe.d/blacklist.conf, this module disable keyboard / mouse thinking the laptop was a tablet. – Nicolas Dec 12 '20 at 18:50

I had the same problem and tried reinstalling the drivers and updating kernel but didn't help. So I went to the BIOS configuration and checked if the mouse pointer worked there. Initially I couldn't see the cursor in the BIOS menu but I tried to enable the mouse pointer by pressing Fn + F5 (might be different in your case) and the mouse cursor started to appear and worked in the BIOS menu. I simply restarted my system after that and logged into Ubuntu and the touchpad worked.
