Estou executando o teste Debian em uma VM do VirtualBox (host do Windows 10, VBox 5.2.20) e inicializando no console. Eu costumava ser capaz de executar o startx muito bem uma vez logado, mas para o passado, enquanto isso não funcionou, e eu gostaria de corrigi-lo.
Eu tenho conseguido por um tempo, indo para a inicialização avançada, escolhendo à prova de falhas, pressionando CTRL-D quando solicitado pela senha do modo de manutenção, em seguida, fazer login normalmente e executando startx, o que funciona.
Uma diferença notável nos logs entre a inicialização normal e a inicialização segura é que há um erro referente a /dev/dri/card0 não existente ao chamar startx após uma inicialização normal, mas /dev/dri/card0 é encontrado e usado no startx a partir da inicialização à prova de falhas.
Aqui está o conteúdo completo de /var/log/Xorg.0.log quando tento executar o startx depois de fazer o login no console.
