Emerge

Those using the package for the VNC server need to install the package with the server USE flag enabled. This can be added to the package.use file (or directory), or specified one-shot-like on the command-line:

root #USE="server" emerge --ask --update --newuse net-misc/tigervnc
Note
Setting USE="server" as displayed in the example above will emerge the package with the specified USE flags, however the flags will not be preserved upon package upgrades. Be sure to set them in package.use in order to make flags persist when applying system updates.

Those installing just the client can simply emerge the package:

root #emerge --ask net-misc/tigervnc

Configuration

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

Set a password:

user $vncpasswd

Start the server:

user $vncserver

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

Once finished, kill the running vncserver:

user $pkill Xvnc

Displays

Setup the displays. Substitute each 'user' value below with the name of a user who will be running the VNS 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.

Desktop environments

Each user who will be running a VNS server can configure an X startup script. This script can define which desktop environment will be used for the X server to run when connecting a client to the server. For example:

FILE ~/.vnc/xstartup
#!/bin/sh
startkde &
#startxfce4 &
#startfluxbox &
#fvwm2 &
#icewm-session &
#startlxde &
#xfce4-panel &

lxterminal

Edit the VNC startup script:

FILE ~/.vnc/xstartup
#!/bin/sh
xrdb ${HOME}/.Xresources
xsetroot -solid black
lxterminal &
/usr/bin/lxsession -s LXDE &

twm

Edit the VNC startup script:

FILE ~/.vnc/xstartup
#!/bin/sh
xrdb ${HOME}/.Xresources
xsetroot -solid grey
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &

Make sure the xstartup file is executable:

user $chmod +x ~/.vnc/xstartup

Services

OpenRC

Start the server:

root #service vnc start
