Eu tenho o servidor ubuntu instalado no meu servidor XEN. Agora, devido a algumas razões, eu preciso configurar alguns aplicativos baseados em GUI no Ubuntu, para que eu instalei o Ubuntu-desktop via apt-get. Agora, quando eu quero usar startx, isso me dá erro abaixo. Eu estou usando o console do Xen Center.

Você está usando algumas placas gráficas (em particular, ou outro hardware em geral) que exigem módulos / drivers de propriedade? Esta é a causa mais comum de exibição de console / nenhum gráfico em domínios Xen. Nenhuma detecção de dispositivos também indica que faltam módulos adequados para hardware.
