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

  • Sorry for bad formatting this my first post... I was not expecting all text being put together... I can paste showkey output again if required... thanks – ArmandoTL Nov 01 '20 at 11:05
  • I'm using Spanish language & layout (ES). Output posted. – ArmandoTL Nov 02 '20 at 17:27
  • sorry, user.dz, still need to learn how to do that nice formatting you do :-) – ArmandoTL Nov 02 '20 at 17:30
  • :) Here how to format it https://meta.askubuntu.com/a/19392/26246 , it is called MarkDown – user.dz Nov 02 '20 at 17:32
  • Probably looking for this solution https://askubuntu.com/a/70788/26246 , new releases seem to disable compose key and 3lvl shift on vanilla installation. – user.dz Nov 02 '20 at 17:46
  • strange... i started running apt-get gnome-tweak-tool, but as it asked me something about a session manager, I aborted this install, ... and guess what... now i can type #@ :-)... in fact now my layout says ES.. i will paste in question. Also changed keyboard to dell Usb, but volume wheel still not working.. – ArmandoTL Nov 02 '20 at 17:59
  • Changing layout, reset it. So it was layout: – for some reason. – user.dz Nov 02 '20 at 18:08
  • mieeees... ok. I will keep on trying to set those media keys. Btw... who will mark this question as solved?.. or shall we leave it open while troubleshooting those media keys? – ArmandoTL Nov 02 '20 at 18:17

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.
