Após a tela de login do Ubuntu 14.04, se eu fizer login no Gnome ou no Unity, apenas o plano de fundo da área de trabalho será exibido. Nada começa. Eu não posso nem rodar o terminal através de ctrl + alt + t.
No entanto, posso iniciar o console usando ctrl + alt + 1.
De lá, tentei iniciar a união e isso funciona apenas parcialmente. Os ícones e a barra lateral aparecem quando eu volto para o desktop a partir do console, mas é muito lento, com bugs e inutilizável.
Este é o log da unidade de execução do console (eu corro com "sudo unity", então eu mudo para desktop e ele começa, mas é buggy, então eu paro no console):

Em seguida, os avisos "Falha ao confirmar alterações" continuam por todo o arquivo de log de ~ 30MB. Eu eventualmente tenho que pará-lo do console.
O que eu tentei até agora:
Quando estou instalando o ubuntu-destkop e o gnome e suas dependências, recebo este erro:
Unable to autolaunch a dbus daemon without a $DISPLAY for X11
(Escrevi isso, então não tenho certeza se está 100% correto).
Destes, apenas instalando o fluxbox funciona.
Estou escrevendo este fluxbox conectado e funciona sem problemas. No entanto, quando escolho o Gnome ou o Ubuntu a partir da tela de login, o mesmo problema de nada inicializar persiste.
