# Ubuntu – Some function keys stop working

keyboardkeyboard-layoutshortcut-keys

I have some problem with my built in (also externeal) keybord.
Function keys (volume up/down, mute) and polish characters (right alt) are not working anymore. Right alt behave in the same way as left alt (open HUD). I also can't entry polish characters with Onboard (on screen keyboard).

What I tried:

• Function keys are correctly configured in system settings->keyboard->shortcuts, system see them correctly (I tried to change this and I am able to do it)

• There is polish keyboard layout selected

Anybody have idea how to fix it?

I ran ibus-setup and manually selected polish on entry setup page
