VNC & Suse 8.2 Success with init 5 but Grey window with init 3
- From: "R. S. Patil" <kpr_rspatil@xxxxxxxxxxxxx>

Dear Friends,
I have very good results when linux box suse 8.2 Pro is
running in init 5 mode but i am getting a grey window
when its in init 3 mode. The lsof command output
shows that vnc server is running but kdm is not
listening on port 177.
My settings are as listed Below. Can somebody help me
in this regard. I would like to access This Linux box
irrespective of whether running in mode 5 or 3.
Since this box is a database server local administrator
often puts it into mode 3 when it slows down in mode 5
Best Regards
R. S. Patil
==========================================
OS = Suse 8.2 pro
Real VNC = VNC vnc-4.0-0b4.i386.rpm
Client = WinVNC B4 on Win XP (Dell-Laptop)
1) in /etc/services added lines
----------------------------
vnc640x8 5950/tcp # Small
vnc800x8 5951/tcp # Medium
vnc1024x8 5952/tcp # Large
vnc640x16 5960/tcp # Small
vnc800x16 5961/tcp # Medium
vnc1024x16 5962/tcp # Large
2) created new file /etc/xinetd.d/VNC
----------------------------------
service vnc640x8
{
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/bin/Xvnc
server_args = -inetd -query localhost -once -geometry
640x480 -depth 8 securitytypes=none
}
...... similar for rest of services
When user was nobody I was getting grey screen with
X cursor and no login screen. I changed nobody to root
which was mentioned on some web page which I don't remember
3) Edited /etc/X11/xdm/xdm-config
------------------------------
commented "! DisplayManager.requestPort: 0"
4) edited /etc/X11/xdm/Xaccess
---------------------------
uncommented * #any host can get a login window
5) edited /etc/opt/kde3/share/config/kdm/kdmrc
-------------------------------------------
in the XDMCP section changed enable = true
6) In Yast2-.>System->Sysconfig Editor
-----------------------------------
changed DISPLAYMANAGER_REMOTE_ACCESS to yes
I think this is only essential setting.
changed DISPLAYMANAGER_ROOT_LOGIN_REMOTE = yes
this is required if security permits root to be
logged in remotely
changed DISPLAYMANAGER_STARTS_XSERVER to no
to make no gui at console if yes doesn't matter
changed KDM_SHUTDOWN to root
even if kept unchanged doesn't matter
changed KDM_GREETSTRING to "welcome To VNC Server"
even if I did this I dont found this greeting
at login prompt
then saved the changes and rebooted system
Aha I can get multiple login windows when tried
to connect in VNC viewer even on same port say :52.
if display port is added in server_args u get
only one connection per port (Ref following)
service vnc640x8
{
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/bin/Xvnc
server_args = :52 -inetd -query localhost -once -geometry
640x480 -depth 8 securitytypes=none
}
if Linux is box is running in init 3 I am getting once again
grey screen. What shall I do if I want the same results
when remote system is running in init 3 mode.
outputs of lsof commands in both cases are as follows.
