Erreur environnement graphique (GNOME)

Bonjour à tous, je possède un serveur dédié sous debian 8 (64bits). J’essaye actuellement d’installer un environnement graphique pour pouvoir avoir accès au bureau de mon serveur à distance.
J’ai donc installer Gnome à l’aide de ces 2 tutos :
wiki.debian.org/fr/DebianGnome

Voici les commandes que j’ai utilisés :
apt-get install aptitude tasksel
tasksel install gnome-desktop --new-install

Après je lance tightvncserver :1, je me connecte mais j’obtiens une erreur qui ressemble à celle-ci :

Avec startx j’obtiens cette erreur :

Merci pour votre aide.

C’est généralement une très mauvaise idée d’installer un environnement graphique sur un serveur. Ça prend beaucoup de ressources, et ça augmente considérablement la “surface d’exposition” au cracking.

Si tu as vraiment besoin d’un environnement graphique sur un dédié, a mon humble avis utilise au moins une machine virtuelle.

P.S. Ça m’étonnerais qu’un dédié ait une carte graphique supportant l’accélération 3D nécéssaire à Gnome en mode normal.

D’accord, de toute façon j’avais abandonné cette idée. Merci pour ta réponse.
