Eu bota o Ubuntu 16.04 LTS com o Windows 10. A instalação do 16.04 parece ir muito bem, e eu tenho tudo configurado do jeito que eu gosto, mas eu estou tendo alguns bugs estranhos que são realmente irritantes . Basicamente, na maioria das vezes eu tento fazer o login, ele congela na tela de login antes que eu possa começar a digitar, ou depois de digitar minha senha e apertar enter, ela mostra apenas o plano de fundo do desktop e a marca d'água Ubuntu 16.04 LTS. Eu posso mover o ponteiro do mouse ao redor, mas é isso! Eu tenho que fazer um desligamento strong, então reinicie. Então, às vezes, vai funcionar, mas geralmente não. Despertando-o do sono em startups subseqüentes, ele congela em algum momento. Isso é tudo em uma instalação nova que é executada sem problemas enquanto funciona. Como posso consertar isso?
Edit: Não consigo inicializar a partir do DVD sem apenas obter uma tela preta. Eu fiz algumas pesquisas, e tentei algumas coisas, mas não consigo entender. Os arquivos que tenho atualmente são úteis?
Editar # 2: Tenha comigo aqui, eu não sei o quão útil isso é ... Foi o que aconteceu quando ele congelou no login ontem à noite, conforme documentado no kern.log. Eu não tenho ideia do que isso significa, mas espero que alguém faça

Onde eu disse que o DAISYUBUNTULINK é igual aos outros links, ele simplesmente me disse que eu não poderia postar mais links.
Rinzwind, obrigado! Você me colocou no caminho certo, e eu fui muito mais capaz de pesquisar o problema depois que você me contou sobre os registros. Eu encontrei muitos outros com o meu problema, e parece que corrigi-lo atualizando para o kernel Linux 4.4.8-040408-genérico. Aparentemente 4.4.0 tem sérios problemas com hardware similar ao meu. Obrigado novamente.
