Parece que você tem um problema semelhante ao meu, por favor, adicione detalhes de sua configuração para este bug:
Eu planejei usar meu velho copmpaq 6710b para algum trabalho de pythonic. Eu instalei o Ubuntu 16.04 nele, mas percebi que ele rodava extremamente lento. Então eu mudei para o Xubuntu, mas novamente, o gui é terrivelmente lento e sem resposta. Então eu dei uma olhada no dmesg
e notei alguns erros. Pesquisando isso me deu uma dica sobre um bug antigo, mas não consegui encontrar nada sobre como consertar isso?
