Problema de teclado estranho

Question

Recentemente, recebi um novo e brilhante teclado da Tracer, mas rapidamente me deparo com um problema. A coisa é meus atalhos de teclado se recusa a trabalhar (ctrl + alt + t; alt + v e também alt + letter (para marcar os acentos em idiomas não ingleses) e em vez disso eles produzem letras maiúsculas.Mais estranho, se eu ligar meu teclado antigo O mesmo acontece se ambos os teclados estiverem conectados ao mesmo tempo: um novo se recusa a usar atalhos, o antigo é bom.

Obrigado pela ajuda!

Resposta do terminal com o novo teclado (ctrl + alt + t):

Em máquinas com Windows, este teclado funciona bem. E sim, estou trabalhando em 16.04 - eu gosto do velho;)
