Eu tenho um teclado USB para jogos (comprado no aliexpress há algum tempo) com teclas em inglês. Funciona perfeitamente no Windows, mesmo com a configuração em espanhol.
O problema é que no Linux as Ctrl Alt AltGrteclas não funcionam, são detectadas todas como Shiftteclas esquerdas. Esta é a saída do xev:

Esta é a saída de lsusb:

E esta é a saída de xinput:

Eu uso o Ubuntutu 16.04, mas nas versões mais antigas o problema é o mesmo. Eu tentei algumas correções e usei a ferramenta gnome tweak, mas não funcionou.
Algumas ideias?
