Invoke Linux GUI On windows using Xming software

In this Article,  we will understand the step by step process to Invoke Linux GUI on windows using Xming software.

To complete this configuration we need to follow below steps and I will also share the issue and its resolution which I have faced during configuration.

  • Download the putty software.
  • Download the Xming software.
  • Connect Virtual Machine through Putty.
  • Invoke Linux GUI using Xming software.
  • Issue and it resolution during configuration.

So now let’s start the step by step configuration.

Download the putty software: –

Connect Virtual Machine through Putty: –

Step 1) My virtual Machine name is “Intern” and it is already running, for your case you just need to start your machine by click on the “Start” tab.

Note: – Here I am using OEL 8.1 ISO image.

Step 2) I am assuming that you have already done with the necessary parts like groups creation, user creation, copy of zip files, and extraction of zip files.

Now check the ipaddress, host name of the machine and check both should be pingable.

  Ipaddress and host name Information: –

Check the IP address and name of the machine

Step 3) Use below command to check both ipaddress and host name are pingable.

Ping through Ipaddress: –

Ping through IP address

Ping through Hostname:-

Ping through hostname

Step 4) Now we need to use putty to save our connection but before that we need to make some settings in putty so that we can see GUI interface.

a) Put your “hostname or ipaddress” under host name and ipaddress tab.

Note: – In my case below are my ipaddress and hostname which I mentioned above as well in screenshots.

Ipaddress: –

Hostname: – root

Put Hostname or Ipaddress

b) Now drop down the SSH tab which is under connection then click on X11 tab then enable X11 forwarding option to invoke GUI interface through Xming.

  • Connection—> 2) SSH—> 3) X11—> Enable X11 Forwarding option.

X11 forwarding setting under putty

c) Now saved the session by giving any name under saved session’s option and then click on open tab.

Note: – I am giving my hostname “root” to save the sessions with above settings.

Saved the session of putty and click on open tab

d) After that you will get another login window as below.

Login through putty

Invoke Linux GUI using Xming software: –

Step 1) Now you can login from your respective user’s and make sure you have open your Xming software as well to invoke the GUI.

Note: – I have login with my oracle user and password and going to invoke the GUI, but before that you need to check your display variable has been set or not, if that is not set then you have to set it before invoking the GUI.

     Command to check the display variable: – echo $DISPLAY;

     Command to set the display variable: – export DISPLAY=localhost:10.0


command to show display variable

Step 2) Now go to the “database” folder to execute the “./runInstaller command”.

execute the runInstaller command

GUI has been successfully invoked through Xming.

GUI has invoked through Xming successfully

Issue and it resolution during configuration: –

When I was trying to login through putty with below IP address then I was getting connection timed out issue.

Ipaddress: –

ipaddress information

Issue: –

connect thorugh ipadress and getting connection timed out error

Resolution: –

Step 1) First we need to check the firewall status, if they are enable then we need to disable it.

Command: – service firewalld status

firewall status and its running

We can see firewall is running now we need to stop the firewall.

Command: – service firewalld stop

firewall stop

Now the firewall has been stopped, so let move to check the status of selinux.

Path: – /etc/selinux/config

As we can see from below screenshot selinux status is disabled and it should be in this state, if it in another state then you needs to change it and then reboot the machine.

selinux should be disabled

Step 2) After stopped the firewall, still  getting the same connection timed out issue then I searched more for the issue and got that the subnet of my physical machine IP and got my Virtual Machine subnet is different.

connect thorugh ipadress and getting connection timed out error

Physical  machine IP address: –

physical Ip address info

Virtual machine IP address: –

virtual ipaddress info

We can see that both are in different subnet then I was changed the Virtual Machine IP address to and tried again.

To change the IP address use below steps: –

a) Go to this path /etc/sysconfig/network-scripts and open ifcfg-enp0s3 file to change the ipaddress.

b) Now change the ipaddress so that it can match with the same subnet of Physical Machine.

New ipaddress of virtual machine is

change ipaddress

c) Now put the same ipaddress under/etc/hosts.

ipaddress under etc hosts file

d) Now restart the network services through below command and reboot.

Command: – systemctl restart NetworkManager.service

e) At last check the ipaddress whether it has changed or not.


We can see after reboot the machine ipaddress has been changed successfully.

Step 3) Now first we should check whether we can able to ping from Physical Machine to Virtual Machine.

Virtual Machine to Physical Machine Ping status: –

ping status from Virtual to Physical Machine

Physical machine to Virtual Machine Ping status: –

ping status from Physical to Virtual Machine

Step 4) Now we can check the connection again from putty.

putty connection timed out issue has been resolved


We can see from above output that we are able to login to putty successfully.
