The connection is initiated and a response is received, but only goes as far as producing a black screen with the standard X-server mouse icon (a cross). The mouse responds to input and moves around the screen area, but no graphics are loaded and no login prompt is presented as it was in previous versions of SuSE. Reproducible: Always Steps to Reproduce: 1. Run a standard installation, but de-select automatic configuration. 2. Choose KDE as the default desktop environment. 3. Complete the installation and update the system (currently the system is updated to KDE 4.3.5 during this process) 4. Start YaST 5. Enable Remote Administration, set it to start during boot, and open the required firewall ports. 6. Choose a separate, working machine and start a VNC client (in my case, I tested the KRDC client on openSuSE 11.0 and the TightVNC viewer on WindowsXP with the same results). 7. Attempt to connect to desktop 1 on the remote machine. Actual Results: A black screen with an X mouse cursor appears. The mouse responds to input, but no graphics are loaded and no login prompt is produced. Expected Results: The KDE login prompt should appear and allow the user to begin a remote desktop session. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I removed those and restarted xinetd as per instructions. No change I'm afraid. The only workaround that I know of that works is adding the line: LISTEN 0.0.0.0 to the bottom of the file /etc/X11/xdm/Xaccess Adding this and restarting the machine shows the correct login screen as in previous versions of openSuSE. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It appears that when the user has selected "Disable IPv6" during install, some IPv6 addresses (such as the loopback address) remain in the hosts file. Commenting out these lines returns the proper functionality. Could someone please try to fix these prior to release? Being able to use remote administration is a pretty major feature... especially given that it has its own Yast2 module. Naturally, a fix for 11.2 would be nice as well. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have marked this as resolved fixed, but am hoping that the fix will also be backported to openSuSE 11.2, which displays the same behaviour. Additionally, this bug: https://bugzilla.novell.com/show_bug.cgi?id=546632 may be resolved, but I have no way of checking it against this fix as I am not able to move my current testing network to IPv6. Would someone mind checking and closing the bug if possible?
