I have tried everything to solve this problem like :

export DISPLAY=:10.0
export DISPLAY=localhost:10.0

I tried also the port 0.0 but i get always the same error

after trying xhost 

xhost +local:all
xhost:  unable to open display ""
xhost:  unable to open display ":10.0"

how can i fix this i thought that the X Server is not runing so i tried startx its says its runing at that port

my system is Ubuntu server edition 10.04

In my case I have this exact error when I was launching the Jetbrains IDEs, such as Pycharm, IntelliJ IDEA...

I typed this in the same terminal that I was using to start the IDE to solve the problem:

export DISPLAY=:1

Then I started the IDE from the same terminal issuing the command pycharm and it worked like a charm.

The output of both IDEs was: enter image description here

check whether $DISPLAY variable is set or not, with the below command:

echo $DISPLAY

if the display variable is not set, run the below command to set, (even if it is set, you can have below one for your session)

export DISPLAY=:0.0

in also have the x display location as :0.0

I had the same issue on the Linux server I was working on. Connecting java to a X11 display worked on the head node, but not on any other. After contacting the administrator, it turned out that the current version of our job-scheduling system (SLURM) did not support X11 forwarding. They had to update SLURM (newer versions of SLURM support it) for it to work.

For me none of the above worked, but after long search this worked for me.

export DISPLAY=localhost:20.0

This fixed my problem

xhost +

but Be aware that xhost + completely deactivates authentication and allows everyone to access all application on your screen.

xhost +si:localuser:root seems to work similar with proper authentication.

If you are trying to export display using su and it still doesn't work. This is what worked for me. Try X11 forwarding for sudo users.

Connect the remote host using the -X option with ssh.

# ssh -X root@remote-host

Now list the coockie set for the current user.

# xauth list $DISPLAY
    node01.thegeekdiary.com/unix:10  MIT-MAGIC-COOKIE-1  dacbc5765ec54a1d7115a172147866aa
# echo $DSIPLAY
    localhost:10.0

Switch to another user account using sudo. Add the cookie from the command output above to the sudo user.

# sudo su - [user]
# xauth add node01.thegeekdiary.com/unix:10  MIT-MAGIC-COOKIE-1  dacbc5765ec54a1d7115a172147866aa

Export the display from step 2 again for the sudo user. Try the command xclock to verify if the x client applications are working as expected.

# export DISPLAY=localhost:10.0

I have fixed this issue by logging in using Xorg. By default, I have used Wayland. It looks like Wayland eliminates most of the design flaws of the Xorg it has its own issues.enter image description here

Mine issue was with the firewall. Disabled it temporarily.

[EDIT] And, the server hostname was pointing to another IP. Set it to simply localserver. strace xclock helped to debug this issue.

First do this either in Build Phase of Jenkins if using or set in /etc/profile:

unset DISPLAY
export DISPLAY=:0

then set this property either in java code or using maven: -Djava.awt.headless=false

In my case this error was not related to the DISPLAY port. I was trying to load an XML into Windchill (a PLM-software) and received only the above error on the terminal. In a logfile I found the report that my XML-file was corrupt. Maybe someone has a similar problem and can use this answer.

For Ubuntu 17.10 Install X virtual frame buffer (xvfb)

apt install xvfb

And added these lines to the /etc/profile file...

# Start the X virtual frame buffer (Xvfb)
if [ -f /usr/X11R6/bin/Xvfb ]; then
/usr/X11R6/bin/Xvfb :1 -screen 0 1366x768x32
fi

# Set the DISPLAY variable for the X virtual frame buffer (Xvfb)
export DISPLAY=localhost:1.0

If you're triggering your code from Jenkins, enabling the option "Start Xvfb before the build, and shut it down after" might help. It helped me.

For me logging in as -Y instead of -X worked.

In case you've got untrusted X11 as shown below, then try -Y flag instead (if you trust the host):

Warning: untrusted X11 forwarding setup failed: xauth key data not generated

I was using Xming and got similar error. Following steps were taken to fix the issue:

  1. In Xming launch check the box no access control.
  2. In putty ran the following command: DISPLAY=XXX.XXX.XXX.XX:0.0; export DISPLAY

Replace XXX.XXX.XXX.XX with your IP address.

In my case there was no space left in my machine and I faced the same issue. Some times it could be the space issue. Check the space in your Linux/Unix environment and make sure your machine have enough space.

For me, the problem was that xorg-x11-xauth wasn't installed. I installed it and then it worked.

The packages that I have now are:

  • libX11-common-1.6.3-2.el6.noarch
  • libX11-1.6.3-2.el6.i686
  • libX11-1.6.3-2.el6.x86_64
  • xorg-x11-drv-ati-firware-7.6.1-2.el6.noarch
  • xorg-x11-xauth-1.0.9-1.el6.x86_64

Michael-O gave useful approach to solve the problem. Another way to solve this is by starting the server with Putty Console.

If you start application on a remote server while logged in by ssh then another way would be to start ssh with -x parameter or add ForwardX11 no in your /etc/ssh/ssh_config. In this case ssh will not create environment variable DISPLAY.

In case anybody trying to run the automated unit tests via maven-surefire-plugin on CI(jenkins,..), and getting the above mentioned error, be sure to update your surefire plugin configuration :

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-surefire-plugin</artifactId>
     <version>${maven-surefire-plugin.version}</version>
     <configuration>
            <systemPropertyVariables>
                <java.awt.headless>true</java.awt.headless>
            </systemPropertyVariables>
      </configuration>
</plugin>

You need to specify the -Djava.awt.headless=true parameter at startup time.
