Esta é a segunda vez que este problema aconteceu comigo e eu realmente não quero fazer uma nova reinstalação do Ubuntu novamente. Eu estava mexendo em ambientes de desktop e instalei o Xubuntu, o KDE, e não gostei da tela de login, então voltei ao Unity. Meus jogos funcionaram bem no Xubuntu e Unity, mas os problemas aconteceram depois que eu tentei instalar o Plasma, onde a primeira tentativa de instalação falhou, então eu tive que redefinir algumas configurações para ter uma segunda tentativa bem-sucedida.
O mesmo tipo de problema aconteceu comigo quando tentei instalar o Steam no Unity pela primeira vez (o que eu consegui consertar fazendo uma nova reinstalação do Ubuntu):
No início, o Steam não seria lançado, mas encontrei a solução com um rápido uso do googling. Então, os jogos não seriam lançados. (nada acontece depois que a janela "Preparando-se para lançar o jogo" fechar) O processo do jogo está em andamento (com ~ 10mb de memória).
Eu tenho os drivers corretos do Mesa instalados para minha GPU AMD e meu OpenGL está atualizado.
Aqui está o log quando tento abrir um jogo como o Counter-Strike: Global Offensive:
