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.
3I 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.
try using an external mouse or keyboard. If the problem still persists then you could try seeing if there are any updates available. If nothing works, try reinstalling Ubuntu.
Hope this helps!!
