X client 'Can't open display' on OS11
I'm having a difficult time getting a remote x client to display on my machine. I have an xserver running locally, and connect via ssh. I turned on X11 forwarding in remote host sshd_config: X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost yes I set the local ssh(OpenSSH) connection for X11 Forwarding. An X server, Xming, is running locally. X on the remote host is running without listening on port 6000: # ps -ef |grep X root 1940 1924 0 Aug20 tty7 00:34:30 /usr/bin/X :0 -audit 0 -br -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7 netstat -an |grep 6000 returns nothing. Running an X client doesn't work: oracle@oraman:~> xclock Error: Can't open display: It's my understanding that with tunneling I don't have to turn on TCP listening for ssh on the host. I checked the SDB and seem to have things set up correctly, but it's not working. What am I missing? -- DonMLewis ------------------------------------------------------------------------

Sorry, no one has answered you. I would love to help you out, except I have the exact same problem, and I don't know what to do either. Did you ever figure this out? -- zak89 ------------------------------------------------------------------------ zak89's Profile: http://forums.opensuse.org/member.php?userid=10788 View this thread: http://forums.opensuse.org/showthread.php?t=394056

I use suse 11.3 on PIII, loaded with <init 3>, as gateway to/from internet. I access my data on this gateway with, for example, <gedit &> at home or outside with xming+putty. On suse 11.4/12.1 i cant't use gedit in such way. I get error: "Cannot open display". This issue is from suse 11.4/12.1 only, because there is no problems with 11.3. -- makauskas ------------------------------------------------------------------------ makauskas's Profile: http://forums.opensuse.org/member.php?userid=45338 View this thread: http://forums.opensuse.org/showthread.php?t=394056

Then log as normal user <gnomesu gedit> through the same "Cannot open display" error in putty window. And I'm not asked for any password ! With <su> in putty <init 5> <gedit> I have the same error "Cannot open display" But with suse 11.3 I can log as normal user into remote and run gedit in window on local WinXp. Suse 11.3 is loaded with run level = 3. With suse 11.4/12.1 can't do it remotely. -- makauskas ------------------------------------------------------------------------ makauskas's Profile: http://forums.opensuse.org/member.php?userid=45338 View this thread: http://forums.opensuse.org/showthread.php?t=394056

xrdb: Connection refused AND xrdb: Can't open display ':1002'
Hi everyone, I'm trying to log into an LXDE workstation over FreeNX/NX. I've recently upgraded from 11.4 to 12.1. New users created after the upgrade can log in while users that existed on 11.4 cannot. The NX authentication succeeds and the !M window appears for about 3 or 4 seconds, then disappears. Looking in the ~/.nx/C-host-xxxx/sessions file shows the following errors below. Also a core file appears in the user's home directory, but I don't know how to analyze it. Any ideas on what is failing and how to fix it? Info: Established X client connection. ...
