sempre que eu faço o login, a tela fica preta, vejo um vislumbre do texto do tipo terminal e, em seguida, ele me traz de volta à tela de login (Ubuntu 12.04). Eu posso entrar e fazer o login através da linha de comando. A conta de convidado funciona. Eu acho que isso aconteceu porque eu editei alguns arquivos relacionados ao Xorg tentando fazer um monitor externo funcionar com meu laptop. Eu copio colado de um post do fórum, então eu não lembro o arquivo ou o que eu coloquei no arquivo. Não é possível encontrar a postagem no fórum novamente e meu histórico bash não foi gravado naquela sessão.
Eu tentei reinstalar o Xorg e o ubuntu-desktop, nvidia, redefinindo qualquer configuração que eu pudesse encontrar ... Estou realmente sem saber o que fazer. Aqui está meu /.xsession-errors:
