Ubuntu :: Starting Xterm From Remote - Error: Cannot Open Display A.b.c.d:0.0
Sep 1, 2011
I am running hummingbird exceed on Workstation with an ip address of a.b.c.d, and connecting to a sun machine with IP address x.y.z.w running Solaris with XDMCP. From the sun machine, we commonly telnet to other sun and linux machines and run X applications.
We have just installed ubuntu 10.04, and I can telnet into that machine no problem.
However, running xterm on the ubuntu machine fails:
I tried to connect to remote server ,which is installed Centos 5.4 x86, through Xmanager on windows 7, and got this error.
/usr/bin/xterm Xt error: Can't open display: %s
At the remote server, I turned on firewall and after this I got the above-mentioned error message. I do this accrding to instruction on remote server.
2. Firewall (TCP/UDP Ports) Configuration Open UDP port 177 from the PC to the remote host direction. Open incoming TCP ports 6000~6010 from the remote host to your PC. After adding these ports "/etc/sysconfig/iptable" as the enoder mentioned, /etc/init.d/iptables restart
3. Reboot the remote host and start Xmanager <- I could not restart remote server.
I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1. echo $DISPLAY localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2. echo $DISPLAY <no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.
java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02, mixed mode)
And when i am trying to run my gameserver scripts i get this error.
root:~# /home/l2jserver/login # ./L2JConfig.sh Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it.

This is not my desktop computer but my remote server.
Well this is my first time using redhat 7, the install went fine and webserver, mysql, phpmyadmin are all working......great
The only problem i have is the remote desktop
I have set the password in preferences/remote desktop run command vncpasswd and set password
In services vncserver i get this message......... xsetroot: unable to open display '' Xvnc is stopped and vncserver failed. The error was: xsetroot: unable to open display '' Shutting down VNC server: 1:user1[FAILED]
Starting VNC server: 1:user1 [FAILED]
My vncservers file looks like this
I have tried restarting service using root login and user1
For some reason my gnome-terminal is starting in / when it should be ~ I have checked /etc/profile, ~/.bashrc and /etc/passwd and everything seems fine as far as i can tell Konsole and xterm are starting up with the working dir to my home dir (as set by /etc/passwd) But im at a loss to see where gnome-terminal is starting in / if i enter cd with no argumants in gnome-terminal it is switching to ~ fine, so i dont think its mistaking my home dir for /
I was trying to remotely log in to my desktop which uses 11.3 from my laptop via ssh. For some reason I get an empty field for the command echo $DISPLAY. and as a result an xclock command results in error: can't open display. I tried to set it to localhost:10.0 and I get: Error: Can't open display: localhost:10.0
I've tried :0.0 and I get: Invalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: :0.0 ssh used to work about a week ago before I performed various security updates. I was wondering what' the solution to this. I checked the /etc/ssh/sshd_config file and ssh_config file both have X11 forwarding on. Can anyone with more experience out there give me any ideas?
When I attempt to use Putty for xterm (to run DBCA for Oracle) I check x11 and put my IP Address in the Display field of putty. However, when I then try to execute ./dbca I receive the following:
Xlib: connection to "localhost:10.0" refused by server Xlib: PuTTY X11 proxy: wrong authentication protocol attempted Error: Can't open display: localhost:10.0
I notice the following when logging in to the server as well.
Last login: Fri Mar 19 13:51:19 2010 from 10.47.48.33 /usr/X11R6/bin/xauth: error in locking authority file /home/oracle/.Xauthority. These are the same steps I take successfully on all the servers. The above file exists on the servers I can initiate the GUI, but not on <server1>.
For awhile I have had this issue with the command line and every time I try to complete any command that requires GTK graphics, It always returns the error "Error: cannot open display: 0:" The "EXPORT display" command that I normally use to fix this issue is not working. The only issue that I can think might be the cause for this could be my upgrade to natty (which was in fact a clean installation), or when I edited plymouth so that the startup and shutdown animations would match my laptop's native resolution (by the way I would also appreciate it if I could do the same with the startup animation, only the shutdown really works). If anybody know how I could resolve this issue I would greatly appreciate it. Oh and for specifics on my machine, I am using an ASUS N82 with an NVIDIA GEFORCE GT335M graphics card, running Ubuntu 11.04.
So I just installed 32-bit Squeeze. I've done exactly two things since booting into the first install: pt-get install gtk+2.0, and ./firefox, so unless gtk did something, this might be an easily fixable problem with Debian itself. After installing gtk and trying to run firefox via command line, it tells me
Code: Error: cannot open display: :0 I googled a bit and couldn't come up with a solid solution, but the problem seems to be around other places. Any idea how to fix this?
I have X Window running on one of RHEL Machine 192.168.2.2.I have logined through putty from remote Windows Machine 192.168.2.5. Now What I need to open the xterm (if I run the command through putty it should open xterm in the linux Machine).
If I do setenv DISPLAY other_machine:0 and launch a gui application I can send this application to my other_machine Is there any mean (utility or whatever) to send an OPEN application to another machine (by its pid eventually) So if I have an nedit open, and its pid is 13245, I could do something like send_to_display pid=13245 machine=other_machine:0
Well after messing with compiz Opacity I managed to make all panels and windows transparent. Only thing I see is desktop background and icons. Tried ctrl+although+f1 and running gconftool-2 --recursive-unset /apps/compiz Then a reboot. Same issue. Next ran metacity --replace I get: Windows manager error: Unable to open X display
I also had ever tried all methods they mentioned, but my problem is still there. I am using a MAC OS X 10.6 ssh a remote redhat server. I hope to see X of redhat on my own MAC. Below is what I've done: 'MAC_ip' stands for my mac; 'redhat_ip' stands for redhat server.
1) ssh to redhat server 2) change to root 3) type command: DISPLAY=MAC_ip:0.0 4) type command: export 5) Back to MAC 6) change to root 7) type command: xhost +Redhat_ip 8) vim /etc/ssh_config, add X11Forwarding yes 9) Back to redhat, type: xclock
I got below message: Error: Can't open display: MAC_ip:0.0 I also tried some methods to login as others suggested:
I wrote a simple code using Open Inventor(OpenGL) classes to print a Sphere in a .png file.I tested it on Windows and it worked well.But when I run it on Fedora 10, I got the following error with no output .png file:
Coin error in glxglue_init(): Couldn't open NULL display. Coin warning in SoOffscreenRenderer::renderFromBase(): Could not set up an offscreen OpenGL context. Segmentation fault
Gnome Forum have told me that changing the appearance of gdm I run: sudo -u gdm dbus-launch gnome-appearance-properties but I get this error: (Gnome-properties-Appearance: 18 047): Gtk-WARNING **: can not open display:
Start xpdf or gv. Click an xterm to be active and slide it over xpdf/gv. Vertical lines from xpdf/gv under the xterm stick to the xterm window above and make it unreadable.
The problem does NOT show with KDE default settings with display effects on but does show in fvwm, xfce etc, and in KDE without effects.
On a system with a Sandy Bridge integrated graphics (i5-2400) the problem went away by downgrading to xf86-video-intel-2.13.0. But it was not enough for another system with 945G which needed downgrading to xf86-video-intel-2.12.0.
I recently installed opensuse 11.4 on a remote server. It has GNOME installed as a desktop. The problem I am experiencing is that when logged in through VNC, most of the GUI apps are not functioning, especially ones that require root privs. Example: The Add/Create users context does not function. After you supply root pw, nothing happens. If you launch it from a terminal, you see this:
jjmuw@g01:~> xdg-su -c /sbin/yast2 users Xlib: extension "RANDR" missing on display "::1:1.0". No protocol specified No protocol specified
(y2base:4872): Gtk-WARNING **: cannot open display: ::1:1.0
Followed by a hang. This is also affecting things like the Xen configuration contexts (creating/managing VMs).
