Tenho um Das Keyboard 6 Professional conectado a um computador desktop executando o Ubuntu 20.04. Aleatoriamente, as luzes do teclado se apagam e o teclado fica sem resposta. Depois de alguns segundos, as luzes do teclado acendem novamente e o teclado funciona novamente.
Entrei em contato com o suporte técnico do Das Keyboard e eles acham que isso não é um problema com o teclado, mas um problema com o Ubuntu, possivelmente gerenciamento de energia. Eles disseram que também pode ser interferência eletromagnética.
Não sei se é imaginação minha, mas parece que isso acontece com mais frequência quando não uso meu mouse sem fio por um tempo e depois o movo de lugar.
Não consigo tentar conectar o teclado em outra porta USB porque ela é USB-C e meu computador só tem uma porta USB-C.
Isso é realmente um problema do Ubuntu? E se for, há uma maneira de consertar?
Estou aberto a atualizar o Ubuntu para uma versão mais recente.
Editar: Conforme sugerido por @Vercingatorix, executei dmesg após o desligamento mais recente. Isto é o que obtive:
