Since I've upgraded to 20.04 LTS I'm no longer able to use AltGr key to write percentage sign, hash,at...etc. Also volume up/down wheel and media keys are no longer working. I've changed the keyboard physically to a different model, but still the same. In configuration, I've also changed keyboard type from Dell USB, to pc 102 intl and some other options but no difference. Below showkey when I press volume wheel up, down and AltGr:

código de tecla 115 pulsada
código de tecla 115 liberada
código de tecla 114 pulsada
código de tecla 114 liberada
código de tecla 100 pulsada
código de tecla 100 liberada

Output from lsusb:

Bus 003 Device 008: ID 413c:2011 Dell Computer Corp. Multimedia Pro Keyboard
Bus 003 Device 007: ID 413c:1005 Dell Computer Corp. Multimedia Pro Keyboard Hub

Appreciate your guidance here.... Armando

Not beeing able to find a reasonable way to make my standard dell multimedia usb keyboard work properly after the upgrade, I decided to install 20.04 again from scratch, and surprisingly, everything works as it should. Even odd behaviour with my old logitech camera and skype, it started to work normally since the very first moment. No idea how upgrading from previous LTS could have created such a weird and undesireble behaviour. Thanks a lot for sharing your knowledge trying to fix this issue, but definitively, there were many other things in the background that probably were not working fine.
