[Résolu] VNC serveur sur Ubuntu 20.04

samprzyswa · Le 01/05/2022, à 16:18

Bonjour,

J'ai en fait mal formulé ma question au départ, j'ai trouvé un tuto "https://www.digitalocean.com/community/ … u-20-04-fr" qui décrit la procédure à suivre avec "tightvncserver" pour un serveur Ubuntu sans interface graphique à la base et il propose d'utiliser xfce4 et de le lancer à chaque connexion.

Mais impossible de le faire fonctionner même avec Xfce, beaucoup de message d'erreur.

Est-ce que je peux lancer le serveur VNC sans avoir à lancer Xfce ?

Merci d'avance pour vos lumières...

Sam.

Oui c'est en gros ce que j'ai fait mais j'ai des messages d'erreur:

Aucun retour de cette commande...

Sinon est-ce que tu sais comment on configure Xtightvnc pour modifier la résolution de l'écran ?

Ok merci effectivement ça va m'aider, mais où se trouvent les infos pour générer ces commandes passées à Xtightvnc

ps -ef | grep Xtightvnc

J'ai trouvé dans /usr/share/doc/tightvncserver un truc qui je crois répond à ma question:

# /etc/vnc.conf written by Marcus Brinkmann. This file is in the Public Domain.
#
# This is the configuration file for the vncserver package.
# It is perl syntax, but only variable assignment is allowed.
# A semicolon will be added if missing.
# Every value has suitable defaults, so you probably don't need any file.
#
# This file will be sourced by `vncserver' and `vncpasswd'.
# After this file, $(HOME)/.vncrc will be sourced, so values can be
# overwritten on a per-user basis. If you want to reactivate the default
# value there, you have to specify an empty value. For example, $fontPath
# will set to the default value after
#
# $fontPath = "/foo";
# $fontPath = "";
#
# If you are missing something, please let me know.
# Marcus.Brinkmann@ruhr-uni-bochum.de

# System configuration
# --------------------
#
# This section contains entries that should be true for all users.

# $vncClasses should be the path to the java classes of server.
# $vncClasses = "/usr/share/vncserver";

# $XFConfigPath   can be set to the global XF86Config file. This will be
#                 parsed to gain default values for $fontPath and $colorPath.
#                 If you want to disable this feature, point it to an
#                 invalid file, "/foo" for example.
# $XFConfigPath = "/etc/X11/XF86Config";

# $fontPath should be a comma seperated list of fonts to be added to the font
#           path. If not specified, and $XFConfigPath is valid, vncserver
#           will read the $fontPath from there. If both are not set, the
#           default will apply.
# Example: $fontPath = "tcp/localhost:7100";     # would make vnc to use xfs.
# Example: $fontPath = "";
#	$fontPath .= "/usr/X11R6/lib/X11/fonts/misc/,";
# 	$fontPath .= "/usr/X11R6/lib/X11/fonts/75dpi/:unscaled,";
# 	$fontPath .= "/usr/X11R6/lib/X11/fonts/100dpi/:unscaled,";
# 	$fontPath .= "/usr/X11R6/lib/X11/fonts/Type1/,";
# 	$fontPath .= "/usr/X11R6/lib/X11/fonts/Speedo/,";
# 	$fontPath .= "/usr/X11R6/lib/X11/fonts/75dpi/,";
# 	$fontPath .= "/usr/X11R6/lib/X11/fonts/100dpi/,";
#	$fontPath .= "/usr/X11R6/lib/X11/fonts/freefont/,";
#	$fontPath .= "/usr/X11R6/lib/X11/fonts/sharefont/";
# I don't know what the default is, though.

# $colorPath should be the RGB file to be used by X. This can also be taken from
#            XF86Config file if specified by $XFConfigPath
# $colorPath = "/usr/X11R6/lib/X11/rgb";

# User configuration
# ------------------
#
# This section contains entries that may change from user to user.

# $vncUserDir contains the filename for the log files directory of Xvnc
#             (the server) and the viewers that are connected to it.
# $vncUserDir = "$ENV{HOME}/.vnc";

# $vncPasswdFile contains the filename of the password file for Xvnc.
# $vncPasswdFile = $vncUserDir . "/passwd";

# $vncStartup points to a script that will be started at the very beginning.
# $vncStartup = "/etc/X11/Xsession";

# $xauthorityFile should be the path to the authority file that should be used
#                 by your vnc X server.
# $xauthorityFile = "$ENV{HOME}/.Xauthority";

# $defaultDesktopName should be set to the default name of the desktop.
#                     This can be changed at the command line with -name.
# $defaultDesktopName = "X";

# $geometry sets framebuffer width & height. Default will be calculated if
#           server is started from within a running X servers. Can be changed at
#           the commandline (-geometry). A fixed default will be used if
#           vncserver is not invoked in a running X session.
# Example:  $geometry ="640x480";

# $depth       sets the framebuffer color depth. Must be between 8 and 32.
# $pixelformat sets the default pixelformat.
#              The default will be calculated if none of both is specified
#              and when vncserver is called from within a running X servers.
#              Can be changed at the command line with option -depth.
#              A fixed default value will be used if vncserver is not
#              invoked in a running X session.
# Example:  $depth = "16";
#           $pixelformat = "rgb565";

# $getDefaultFrom sets the display from which you can query the default of
#                 the above three options, if you don't want to start vncserver
#                 from within a running X server. It will be added to the call
#                 of xdpyinfo.
#                 It is useful to get the default from the X server you will
#                 run xvncviewer in.
# Example:  $getDefaultFrom = "-display localhost:0"

# $rfbwait sets the maximum time in msec to wait for vnc client viewer.
# $rfbwait = "120000";
