Can't Open Display localhost:0.0
I'm trying to connect to my linux server but I'm having some major problems. The server had OEL 5 installed and my local pc is running Windows XP. I'm using PuTTy to connect to the server with Xming running on my loacl machine. I login as root and run the following command -
export DISPLAY={+ipaddress+}:0.0
I then run xclock and get the following error -
Xlib: connection to "{+ipaddress+}:0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: {+ipaddress+}:0.0
The strange thing is that on my bosses pc (who has got almost the exact same setup ie. PuTTy & Xming) is works perfectly.
Please help.
Thanx in advance.
You normally enter the xhost command in a XTerm window, or you can start Xming with the -ac parameter which disables access control (not recommend). You don't need to use xhost if you make a SSH connection, but from the information you provided it is not possible to determine.
Perhaps the following link will be useful for you: http://www.straightrunning.com/XmingNotes/trouble.php

Putty xming Can't open display
Yes I have googled and went through all Xming trouble? pages. Thanks for asking.
I have a arch box called janus and a xp workstation japetus
on janus /etc/ssh/sshd_config have
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes
on japetus installed: Putty 0.60, under Connection|SSH|X11|Enable X11 forwarding is switched on the X display location is: localhost:0, with MIT-Magic-Cookie-1 protocol
on japetus installed: Xming 6.9.0.31
there is no firewall running on japetus
on japetus started Xlaunch and left Display number: 0
on japetus fired up putty and connected to janus. Contrary to recommend the DISPLAY var is not set, so:
on janus:
export DISPLAY=localhost:0
echo $DISPLAY returns localhost:0 so that is in order
on janus: xlock &
result
Error: Can't open display: localhost:0
I've been over these settings over and over and am not able to get it working. It must be a small simple oversightLogs as attached.

Hello, I hope some may be able to help me finding a solution to this X related problem.
Before Lion everything worked as expected.
From a terminal I
ssh -X user@linuxbox
and it work as expected... all the X application come back to my Mac.
but after a while (generaly not long ... about 5 to 10 min)
I cannot launch any X application anymore.
within my Terminal I get "Error: cannot open display: localhost:11.0"
and on the linuxbox side I get " sshd[xxxx]: channel 4: open failed: administratively prohibited: open failed"
Running 10.7.1. fully updated (from my 10.6.8 Mac I do not have this problem
... and never had)
Thanks in advance for your help
PhS'arch' is set as the alias for localhost. I never entered 'arch' anyway, that's just what the error said.
e: I tried ssh-ing into a X session on another laptop running an Ubuntu live CD. I can ssh into it normally, but when I run 'xinit -e ssh -XCT [email protected] gnome-session -- :1' it just starts a new X session on ctrl+alt+F8 using my startx file, rather than the one on the other computer.

hi.
I can't open xwindows with another user than root, under my solaris 10 x86.
I checked the config, tried lots of things (set a display for my user, put /usr/openwin/bin in PATH,etc), but still the same:
Xlib: connection to localhost: 0.0 refused by server
Xlib: no protocol specified
Error: can't open display
Please help me :)That s ok I found.
You just need to do as follows:
root@localhost: xhost + localhost
root@localhost: su - myUser
myUser@localhost: export DISPLAY=localhost:0
myUser@localhost: xclock &

Unable to open display localhost:0.0 in VMware RedHat linux machine
I have been trying to Install Oracle 10g RAC in VMware linux virtual machine.
my virtual machines are running properly and I am able to use RSH & SSH.
when I run runInstaller it is not comming up due to DISPLAY environmental variable setup.
I have set the varable as follows
DISPLAY=localhost:0.0; export DISPLAY
then if i execute xhost + it gives the following error
"xhost: unable to open display localhost:0.0"
I have tried with ipaddress instead of localhost. Eventhen it is giving the same error
What is the problem? How I can solve the issue?i had the same issue. running the xhost + as root fixed the issue, but only after i switched to root using 'su -' instead of just 'su' (likely something in the profile scripts that get run when you use the '-' (dash) versus just using 'su'.
after running the xhost +, i was able to (as oracle) do:
export DISPLAY=:0.0
./runInstaller
And good to go. -
Xclock Error: Can't open display: - after upgrading to openSSH 5.2p1
I have got two servers apssvrX and apssvrZ on OEL. Both were built by the same team using their standard build scripts.
Having received the servers I had installed Oracle (ODI) product on it successfully.
Then as a part of requirement and as per Oracle support's advise, I had upgraded the ssh version on apssvrX server from OpenSSH_4.3p2 To OpenSSH_5.2p1, so that, I can implement the chroot jailing.
As per Oracle advise, I had downloaded the 3 RPMs from "_http://layer1.rack911.com/openssh/rhel5/x86_64/" to run them on my first server i.e., apssvrX and then configured the sshd services following the below steps:
a) Modify /etc/ssh/sshd_config to comment the below line:
#Subsystem sftp /usr/libexec/openssh/sftp-server
b) Add below lines:
Subsystem sftp internal-sftp
Match Group sftponly
ChrootDirectory %h
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
Then lastly, Restart sshd services complete the configuration
# /etc/init.d/sshd restart
apssvrX server current details are as below:
apssvrX$ uname -a
Linux apssvrX 2.6.18-128.el5 #1 SMP Wed Jan 21 08:45:05 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
apssvrX$ ssh -V
OpenSSH_5.2p1, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
My problems started from this point onwards. I want to install another Oracle product using OUI, but when I try to execute xclock using the Exceed HummingBird tool on apssvrX server then it fails with the error - (xclock) Error: Can't open display:
I tried the DISPLAY variable setup as well but to no use.
Whereas I can successfully execute the xclock on apssvrZ and OUI as well. Its config details are as below:
apssvrZ$ uname -a
Linux apssvrZ 2.6.18-128.el5 #1 SMP Wed Jan 21 08:45:05 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
apssvrZ$ ssh -V

Please advise the way forward.Tried but still same error.

X11 remote app and XQuartz and xterm Xt error: Can't open display: %s
Hi
I have Snow Leopard (10.8.4) and XQuartz on it I need to run X11 remote app on redhat.
On local host echo $DISPLAY shows /tmp/launch-d33HNb/org.macosforge.xquartz:0
When i do ssh -X (or -Y) [email protected] and try to run xterm i got:
xterm Xt error: Can't open display: %s
xterm: DISPLAY is not set
the sshd_config on remote host has
cat /etc/ssh/sshd_config | grep X11
#X11Forwarding no
X11Forwarding yes
X11DisplayOffset 10
#X11UseLocalhost yes
Question is do i need to set up DISPLAY variable on remote host?
If yes which display number do i choose?
if i do export DISPLAY=<my mac ip>:10.0 or export DISPLAY=<my mac ip>:0.0
i still have message xterm Xt error: Can't open display: %s
Maybe this will help also

I'm always looking for new tricks of the trade.
I remember now why I originally changed the ssh config file. Here is another trick: In a text editor, type
ssh://[email protected]
making the obvious substitutions. Select the line and drag it to the Desktop. It will create an inetloc file that, when double-clicked, opens a Terminal window and connects to the ssh session. I have several of these in my Dock.
That is a neat trick. However, with LaunchPad I'm not much of a Finder double-clicker anymore. What is interesting is that the OS knows how to handle the ssh protocol. You can also type "open ssh://[email protected]" for the same effect. That may not seem like much of a gain, but it reveals some interesting OS-level possibilities.
With an RSA key, I don't even need a password
You can use the newer DSA keys. There is another neat trick too. Pretty much every set of instructions I've seen online suggests using an empty private key password because running ssh-agent is such a hassle on Linux. It is built-in to OS X. So, on OS X, you can create more secure DSA private keys with pass phrases that are stored (and encrypted) in your keychain. You only have to supply the Then, even if someone gets your private keys, they get nothing. -
Error can't open display after reboot
Hi,
I encounter this problem :
I just install SSGD 4.2 on Solaris 10 01/06 T2000 server. After installation I can connect to the SSGD using browser from my notebook, and can try the various demo (dtterm, xclock etc)
I reboot the Solaris 10 OS.
After reboot I tried to login again via browser in my notebook and try to run the various demo.
I can login, but almost all the demo failed to execute, the X applications give error "can't open display:" with no hostname following the error.
The only demo still runs is the vt420 demo
Anybody can help me to point out what causes the problem ? I am trying to demo this SSGD software to a customer.
Regards
Adrianus B. KurnadiI've noticed this as well, under Solaris 10 FCS, Solaris 10 U1, and Solaris Express nv_39.
However, I have tried it out under S8 02/04, and S9 09/04 and I do not have this problem after rebooting the host at all.
For the hell of it, I (rather badly) converted the S89/S90 startup scripts to be SMF manifests with S90Tarantella having a dependancy on tS89TarantellaWebServer as I thought perhaps there was a strange issue with the tta process starting before the web service had fully started (beats me why it would matter, ends up it didn't) - as my test S10 host is a slow Netra T1.
I'd be interested to know what the difference is between it being started up via an rc2.d script and the root user logging into the system console running /opt/tarantella/bin/tarantella start. I haven't even bothered starting to try to observe the environment differences between startup via SMF in S10 and init.d in S8.

While installting oracle, i am unable to launch the oracle universal installer. I have already set the DISPLAY value to IPAddress.
I am installing it from ora<sid>, it asking about xlock. When i am running it from root, i am able to open up xclock. But i am unable to open up xclock from ora<sid>. It is giving error as error: can't open display.
Please suggest the solution.
Regards
KarunakarHello,
It already solved!
What I did was:
Open a new Term. session.
Under root user I ran
#xhost + *
(this enables the X window for all users)
Then I don´t needed to set the Display variable with the value user within that Term. session.
#echo $DISPLAY
#:0.0
... then I test xclock to validate the display functionality and then I start oracle wizard installation with command
#./RUNINSTALLER
The oracle installation finish without problems!
Best regards,

Xterm: Xt error: Can't open display: xterm: DISPLAY is not set
Hello, I am completely new to networking/systems. I have been asked to complete an open flow tutorial ( http://www.openflow.org/wk/index.php/OpenFlow_Tutorial ) I have fininshed a part of the tutorial and when i used "ssh -X [email protected]**.*", I was able to log in successfully but when i type in Xterm, it says "xterm: Xt error: Can't open display: xterm: DISPLAY is not set". I have downloaded virtual box, XQuartz and an ovf file as given in teh tutorial. I don't know what the problem is. Can someone please guide me through this? Thank you so much!
I didn't quite understand what you were saying but when i typed "ssh -Y ..." this is what happened:
mobile-172-16-103-167:~ mininet$ ssh -Y [email protected]
Password:
Last login: Sat May 18 20:25:50 2013 from 192.168.56.1
mobile-172-16-103-167:~ mininet$
ssh -X and ssh -Y do essentially the same thing. -Y is just less restrictive on X11 return traffic authority (basically it tells the local X11 display server that you trust the remote system sending X11 traffic to it).
Now what you are display seems strange. You prompt implies that your current system's IP address is 172.16.103.167 and you are ssh'ing to 192.168.56.1. You get a password prompt as expected, but then the "Last Login" messages says you are coming from 192.168.56.1, which is should be where you are coming, but that it the address you are trying to ssh to. And then to top it off, you command line prompt has not changed.
So I'm wondering if 192.168.56.1 is the same system you are currently using, but just a different account on that system?
Is this true?
Also your prompt implies you were logged into the 'mininet' account when you issued the ssh -Y command to login to the 'mininet' account on 192.168.56.1.
Or is it possible that you are loosing track of which system and account you are current remotely logged into? -

[Solved] [Macbook 9,2] xrandr - "Can't open display"
Hi,
after a long time Arch Linux runs on my Macbook!
Now I need an X-Server. After a while it runs too.
But I can't load i3.
When I starting it with:
xinit i3
i3 display: "ERROR: No outputs found via RandR, disabling"
When I use xrandr in commandline, it show's:
"Can't open display"
How can I fix it?
Last edited by DasLampe (2012-09-25 19:29:51)When you say you get that error in commandline, do you mean a tty without X running? If so, that is the expected result.
Not that this is part of a solution, but it may refocus on the problem: X/i3 is failing to start properly, this may not actually be related to xrandr.
As a test, have you / can you try starting the twm session described in the beginners guide? Does that work?
Then please post your ~/.xinitrc. -
VERY annoying thing with XServer "Can't open display" after a while
This issue is *very* annoying I would love if someone could help.
I had this issue for a long time, thinking I'll fix it. I googled, but everybody seems to have the same problem, but no fix (only temporary ones).
So here's the problem : I installed archlinux on my (very old) laptop, everything works great, now I even installed the XServer, which however is causing this problem:
everything works good for a while, but after a while, I can't launch any new programs, but existing ones work good... If I try to start any X-App in an already running terminal, it gives me:
No protocol specified
xterm Xt error: Can't open display: :0.0
However, all already running apps run fine, they even can create new windows!
The only fix I found for this is to kill & restart the xserver with ctrl+alt+backspace.

[fvwm][main]: ERROR can't open display :1
I can start a second xfce (session?) in a tty while I have a normal xfce session running in tty10, by logging into the tty and designating an alternative display. example:
$ startxfce4 -- :1
Now I'm playing around with fvwm and trying to start it in a tty with xfce running in tty10, per the command and error below:
$ fvwm -d :1
[fvwm][main]: <<ERROR>> can't open display :1
I've tried find a solution with no luck. How would I start fvwm in a tty?You have to start another X session. Perhaps xfce hides this fact from you by bundling all that in the startxfce4 script, but any other window manager requires X to already be running.
Use startx/xinit -- :1
You can create conditional entries in your xinitrc so you could do `xinit fvwm -- :1`
Edit: As I don't use fvwm you can test and confirm what I am suggesting by trying to start fvwm from a tty even in the default display before any other x session is running. Calling just `fvwm` from a terminal should fail.
