Emerge

Ci którzy używają pakietu dla serwera VNC powinni zainstalować pakiet z włączoną flagą USE server. Może ona zostać dodana do pliku (lub katalogu) package.use, lub wyszczególniona podczas komendy instalacji:

root #USE="server" emerge --ask --update --newuse net-misc/tigervnc

Informacja
Ustawienie flagi USE="server" jak zaprezentowano w przykładzie powyżej zainstaluje przez emerge pakiet z wyszczególnionymi flagami USE, jednakże flagi te nie zostaną zachowane dla przyszłych aktualizacji pakietu. Upewnij się, że są ustawione również w package.use aby były zachowane w przypadku aktualizacji systemu.

Ci którzy instalują tylko klienta, mogą po prostu użyć emerge w ten sposób:

root #emerge --ask net-misc/tigervnc

Konfiguracja Pojedynczego Serwera

Ta konfiguracja pozwala na zdalny dostęp do całego serwera Xorg X11

The xorg module is always installed, but to make sure it is compatible with the currently installed server, those using this configuration can emerge the xorg-module package:

root #emerge --ask net-misc/tigervnc-xorg-module

Create the TigerVNC config file for Xorg X11:

root #mkdir -p /etc/X11/xorg.conf.d

FILE /etc/X11/xorg.conf.d/40-vnc.conf

Section "Module"
	Load "vnc"
EndSection
Section "Screen"
	Identifier "Default Screen"
	Option "PasswordFile" "/etc/X11/vncpasswd"
EndSection

Create /etc/X11/vncpasswd

root #vncpasswd /etc/X11/vncpasswd

Multiple Server Configuration

Starting with version 1.12, tigervnc no longer supports starting servers as 'normal' user. A global configuration with sessions is now required. This paragraph can still be used to test the configuration.

Login as 'normal' user. The following steps can be taken for any user who wishes to configure the VNC server for remote connection.

Set a password:

user $vncpasswd

Start the server giving it an unused display number (for example :1 or :2):

user $vncserver :N

If desired, use a VNC client on either a local or remote machine to test the connection.

Once finished, kill the running vncserver by pressing C-c.

Displays

Setup the displays for OpenRC. Substitute each 'user' value below with the name of a user who will be running the VNC server on the machine:

FILE /etc/conf.d/tigervnc

DISPLAYS="user:1 user2:2"

Typically the value of :0 will be used for the server's own X display. This is why the example above starts by using the :1 display handle.

The above step is not required for systemd.

Setup the displays in the TigerVNC configuration file:

FILE /etc/tigervnc/vncserver.users

:1=user
:2=user2

Desktop environments

To setup the default desktop environment, add it to session= (or uncomment one from below):

FILE /etc/tigervnc/vncserver-config-defaults

# session=gnome
# securitytypes=vncauth,tlsvnc
# geometry=2000x1200
# localhost
# alwaysshared
 
# Other possible working sessions:
#session=e16-session
#session=enlightenment
#session=fvwm
#session=gnome-classic
#session=gnome-custom-session
#session=gnome
#session=gnome-xorg
#session=LXDE
#session=lxqt
#session=openbox
#session=plasma
#session=xfce
#session=Xsession

Each user who will be running a VNC server can override this configuration by adding it to ~/.vnc/config. There is a file /etc/tigervnc/vncserver-config-mandatory where the system administrator can override user's config. ~/.vnc/xstartup is no longer supported and the current server ignores it.

Services

OpenRC

Start the server:

root #rc-service tigervnc start

systemd

Start the server:

root #systemctl enable vncserver@:<display>.service

for each :display in /etc/tigervnc/vncserver.users

Usage

Connecting

user $vncviewer server:1

Connect over ssh with high resolution

user $vncviewer -Fullcolor -QualityLevel 9 -via user@remotehost localhost:1

user $vncviewer -Fullcolor -QualityLevel 9 -via user2@remotehost localhost:2
