[opensuse] VNC grey screen problem
I am trying to set up VNC on a new opensuse 10.2 installation. When I run vncviewer it connects to the vncserver but all I get is the Xll grey screen with the large X shaped cursor - No xdm login screen! After a timeout period the connection closes and the vncviewer exits. Symptoms are the same when I run vncviewer on a remote or on the local machine. What have I not done? Things I have done: 1. Enabled xinet, and through yast enabled vnc1 - vnc3 2. Through yast enabled xdmcp 3. Turned off firewalling Things I have noticed: 1. There is a duplicate entry in /etc/services for port 5900/tcp. 2. netstat -a shows that xinetd is listening on 5900 3. When I run vncviewer, ps ax on the server shows Xvnc is running I have VNC running OK on a laptop using SuSE 9.3 A difference on the 9.3 version is that the argument :42 appears in the xinetd entries for vnc1,2, and 3 Any ideas?

Yes. When having problems with an application, the first thing to do is to go to that application's website; In this case, visit http://www.vnc.com/

The above source and others are in conflict with each other. The documentation refers to a different method of setup from the one SUSE (open or otherwise) now uses as its default method. Nearly all the documentation refers to running vncserver and vncpasswd. I set up VNC this way many years ago but now use the much more satisfactory method of running Xvnc on demand through the xinetd super-server. As a warning to any other users who would use VNC with openSUSE, don't touch vncviewer or vncpasswd. They will mess things up for you. I have now got VNC going OK on 10.2. But I had to go behind YAST's back and vi the key kdm and xdm files. (This probably means that YAST won't work for other modules which need to change these files unfortunately). To summarise for others who might be interested: 1. Don't at any time run vncserver or vncpasswd 2. Use YAST to enable xinetd services vnc1, vnc2, and vnc3 3. Use YAST to disable firewalling (to allow remote access to the vnc ports) 4. Find and edit the following files (I couldn't find a way to do it with YAST) a:xdm-config: put a ! in front of: DisplayManager.requestPort: 0 b:Xaccess: make sure there is no # commenting out:* #any host can get a login window c:kdmrc: Find the Xdmcp section: Enable=true Port-177 #uncomment if necessary 5. as root, on the console, run the commands: init 3; init 5 to restart X, kde, and other grapohical stuff Warning: openSUSE puts the above files in non-standard places. Use the locate command to find them. It is a nuisance that openSUSE no longer installs locate by default. You will need to install the findutils package. Possibly some or all of the above could be done by YAST. I couldn't find a way to do it. A YAST module for VNC would be nice. Maybe there is one in openSUSE 10.3? To clarify the firewalling setup. VNC should probably be run only on private networks protected from the outside by a separate firewall machine. The VNC server can then safely run without firewalling. Experts may be able to run VNC with firewalling by opening up the ports in the 5900 to 59xx range. The best site for VNC documentation seems to be http://homepage.ntlworld.com/daniel.rigal/xdmvnc.html It would be good if this sort of documentation were on the openSUSE wiki. The current openSUSE wiki document is plain wrong!
