nv era um antigo driver de código aberto para placas da Nvidia, que agora está obsoleto. Certifique-se de não tê-lo em xorg.conf , ou tente colocar na lista negra com echo "blacklist nv" | sudo tee -a "/etc/modprobe.d/blacklist.conf" .
Estou tentando aprender o opengl. Devido a uma falha de hardware, minha máquina principal agora é um laptop antigo que tem um desatualizado. Minha caixa executando Ubuntu 11.10 Server Edition tem uma placa gráfica adequada. Eu gostaria de desenvolver o console para programas opengl de tela cheia na minha caixa de servidor. Atualmente, eu entendo que preciso ter um servidor X e um gerenciador de janelas instalados para que os programas opengl funcionem.
Eu usei os seguintes comandos:
sudo apt-get install xserver-xorg xserver-xorg-core
sudo apt-get install openbox
sudo apt-get install nvidia-173
Para testar o servidor X, executei o xinit, que me deu esta saída:

UPDATE
Escott no efnet apontou que eu não tenho um arquivo /etc/X11/xorg.conf.
Eu corri Xorg -configure , que gerou um, mas também me deu essa saída de erro:

Escott também apontou que eu estava sentindo falta do xterm. Eu instalei via apt-get. Agora, quando eu executo o xinit, minha tela muda a resolução e eu tenho o que parece ser uma linha de comando que se parece com
root@myhostname:~#
xeyes e xlogo serão exibidos
Error: Can't open display:
nv era um antigo driver de código aberto para placas da Nvidia, que agora está obsoleto. Certifique-se de não tê-lo em xorg.conf , ou tente colocar na lista negra com echo "blacklist nv" | sudo tee -a "/etc/modprobe.d/blacklist.conf" .
