14 Installing and Using the Axel-VNCviewer
3.3.1 - LINUX
Under Linux, X terminal devicess (including VNC terminals) are managed by a
Display Manager. A Display Manager provides services similar to those provided
by init, getty and login on character terminals: i.e. prompting for login name and
password, authenticating the user and running a "session".
The most common Display Managers (and their associated daemons) are:
- KDE 2.2:
kdm
daemon,
-KDE:
kdm
daemon,
-GNOME:
gdm
daemon.
To find out which Display Manager is being used by your system invoke the
following command:
# ps -ef | grep dm
Note
: if kdm is used, check if the Display Manager is KDE or KDE 2.2.
If no gdm or kdm daemon is running:
you MUST use a runlevel which
handles graphical displays. This runlevel is operating system dependent.
Generally this is runlevel 5.
The following describes the VNC configuration with KDE 2.2, KDE and GNOME.
a) KDE 2.2 (kdm)
First, XDMCP must be enabled. This is done through the file
kdmrc
. The
location of kdmrc depends on the operating system. Possible locations are
/etc/kde/kdm, /usr/share/config/kdm or /opt/kde2/share/config/kdm.
This file is divided into sections. In the xdmcp section, set the 'Enable'
parameter to 'true':
[xdmcp]
Enable=true
This modification will take effect after rebooting Linux, or invoking init twice to
change the runlevel (invoke
init 3
then
init 5
).
Then the Xvnc daemon must be run through
/etc/inittab
.
