Hi,
I don't know if the problem is connected but since last update X11 crashs after starting kde on the remote Linux-server.
My login procedure is as follows:
- I start X11 with a script (without no window-manager)
- connecting to remote Linux using "ssh -X server"
- starting "kde"
If I use "ssh -Y server" instead, X11 does not crash.
What is the difference between -X and -Y which can cause the crash? Why does it work with -X last week?
Different outputs (in nohup.out)
Connection with "-X" will result in:
- -------------
XFree86 Version 4.4.0 / X Window System
(protocol Version 11, revision 0, vendor release 6600)
[DRI] screen 0 installation complete
Screen 0 added: 1440x900 @ (0,0)
xterm: fatal IO error 32 (Broken pipe) or KillClient on X server ":3.0"
Quitting XDarwin...
- -------------
Connection with "-Y" reslts in:
- -------------
XFree86 Version 4.4.0 / X Window System
(protocol Version 11, revision 0, vendor release 6600)
[DRI] screen 0 installation complete
Screen 0 added: 1440x900 @ (0,0).
Quitting XDarwin...
- -------------
BTW: Why it tries to reach X-Server on :3.0 where it should be open at :2.0?!
Best regards,
Volker Schmidt

I still can forward display to another client system no problem so I know that it not the server having a issue. I finally download XQuartz for Snow Leopard and installed it and after changing ssh_config to "ForwardX11 yes" and "Host to the server I wished to forward from" and rebooted and it now X11 display forwarding works with XQuartz, however, X11 that comes with Apple still doesn't forward the display for some unknown reason.

>>> What is your Firewall setting in the Security System Preference? 10.6.5 is out only a week and did modify X11. I suspect that is when it happened. You do need to apply the latest combo updater any time you reinstall X11 or you are missing important security updates. If you are sure when you updated to 10.6.5 and it corresponds with your problem you should file a bug report with Apple.(If someone hasn't solved the problem for you)

>> The firewall is off in System Preferences and I have latest Security Update of Snow Leopard with release of 10.6.5 on November 10, 2010. I was checking here before I sent a bug report to Apple. Again X11 with Apple worked with display forwarding from another server for two days before stopping over the weekend.
