Eu liguei o monitor VGA e então eu semeei que o Ubuntu está inicializando no modo de console sem GUI, também não consigo ver nada:
Eu consigo fazer o login, mas não consigo ver nada e quando eu desconectar hdmi e reiniciar botas normalmente para desktop e eu ligar HDMI e executar no terminal com este comando
