I have a Dell Vostro laptop running Ubuntu 20.04. The keyboard works fine initially but as soon as I suspend it and then turn it on, it no longer functions. I have to add an external keyboard to do my work OR restart the laptop. It is causing me a lot of trouble. It is clear that it is a software/OS related issue because it only happens on suspension. Kindly provide help.

Edit: F11 and F12 seem to be working as they are used by me as brightness decrease and increase keys.

Edit 2: Adding the specified outputs:

Before suspend:

$ sudo lsusb -tv

This happens occasionally on my Framework 13 laptop. In my case, a workaround is:

  1. Switch to a text console by pressing <CTRL><ALT><F1>
  2. Type some characters on console 1 (ie. the <F1> console) in order to confirm that the keyboard is working.
  3. Return to the graphical desktop by pressing <ALT><F7>.

Can you confirm that you mean that your <F11> and <F12> keys (brightness) work from the resumed OS, even though you can't type characters?
