Installation de xfree86 et gnome

Bonjour,

J’essaye d’installer gnome sur debian mais j’ai quelques petit problème quand je tappe “startx”:

[code]warning: process set to nice value 0 instead of -10 as requested
_XSERVTransSocketOpen: socket() failed for local
_XSERVTransSocketOpenCOTSServer: Unable to open socket for local
_XSERVTransOpen: transport open failed for local/debian:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for local

Fatal server error:
Cannot establish any listening sockets - Make sure an X server isn’t already running

When reporting a problem related to a server crash, please send
the full server output, not just the last messages.

This can be found in the log file “/var/log/XFree86.0.log”.
Please report problems to submit@bugs.debian.org.

_X11TransSocketOpen: socket() failed for local
_X11TransSocketOpenCOTSClient: Unable to open socket for local
_X11TransOpen: transport open failed for local/debian:0
giving up.

xinit: Function not implemented (errno 38): unable to connect to X server
xinit: No such process (errno 3): Server error.
[/code]

Pourquoi ai-je ses erreurs ?

Merci d’avance…
