I am really stuck here.
I want to install and use xorg-x11 linux utility Which i am suggested to use to export UI from EC2 to my local machine.
I have installed "xorg-x11-apps.x86_64" on my ec2 instance.
Normally on the remote site you only need the X11 libraries, not the full blown server. On your local machine you install a X11 server though. I recommend using Cygwin and use the X.org server it ships. Then you do
YOURWINDOWSMACHINE ~ > ssh -X USER#ec2-instance-address
EC2-INSTANCE ~ > some_program_using_X11
Normally, if you install cygwin on your local machine with X, you should be able to export the display and run the remote X application. If you're using something like ssh, have a look at its flags (-x or -X if memory serves)

I have a job that runs denodo platform on remote server. Sh files is a GUI application, and I have to run it to start denodo service. I can't access it in windows, is there a way to solve these problems?
Already running sh files on Putty Windows, but only return null.
If it's a linux GUI application, you should "export display" to view the server screen on your workstation.
Depending of your workstation linux distribution, it might be as easy as :
xhost +<IP_address_of_workstation>
./runMyApp.sh
As your workstation is running windows operating system, you have do further configuration :

https://seanthegeek.net/234/graphical-linux-applications-bash-ubuntu-windows/
If your workstation is connected through SSH you need even more configuration as discussed here : https://unix.stackexchange.com/questions/12755/how-to-forward-x-over-ssh-to-run-graphics-applications-remotely
You can run GUI-Applications of remote linux host in a windows client via ssh (putty) with x-forwarding and an installed x-server (xming)
See this question:

I can launch X11 application through my local machine to X11 enabled server.
e.g. ssh -x from my localmachine(linux desktop) then launch a installed application from the minimal server.
I would like to know if it's possible to access my installed application directly from my minimal server. e.g. ssh -x ?
Thank you.
Not sure if it is useful but better you can use either Xming or Mobaxterm to get an X11 for a linux machine . Ultra VNC/VNC are also some of those kind .
I am trying to install Qt on a Linux machine remotely from a Windows machine using PuTTY.
When I run the command to install Qt on Linux I get the following error:
~/QT# ./qt-unified-linux-x64-2.0.4-online.run
QXcbConnection: Could not connect to display
Aborted
Please suggest any workaround.
You can use the software repository of that Linux distribution.
For example, if it's Debian or Ubuntu:
sudo apt-get install qtbase5-dev
But if you really want to use the installer (usually, when specific Qt version is needed), then try one of the options:
run an X server on that machine
use the --script option of the online installer (you'll have to write a script like here: https://stackoverflow.com/a/34032216/4742108), it will probably need UI anyways
see if the offline installer has an option to run without UI
refer to here: https://community.nxp.com/message/532966
maybe use the cmd "export DISPLAY=:0" and it works
Try to connect with ssh to the host machine using -X to enable X11 display:
ssh <username>#<ip> -X
aqtinstall is a good option: https://github.com/miurahr/aqtinstall
It's a simple command line tool to download and install any Qt version. It's a fork of my old qli-installer script.
I know GUI is for the weak but unfortunately strictly using the terminal isn't an option for me. I have an instance of the Amazon Linux AMI and I have it all set up but I can't find a guide on how to get a GUI on Amazon and how to remote desktop/ VNC into it. I have seen stuff on how to do this for the Ubuntu instance but that is different from Amazon Linux AMI and I don't want to mess up my system or something like that.
So if anyone could point me to where I can find how to do this or tell me how I'd appreciate it
No, you can't. Amazon Linux does not have a Repo for X-server packages. Also, It was meant to be used for Server side roles and hence all he X related stuff is not available.
Consider using Ubuntu OR RHEL ami where you can configure X environment manually by following this and this.
You can set up VNC server for your EC2 Linux boxes. There are tutorials for ubuntu (xrdp) and RHEL (VNC server) in the following websites.
http://devopscube.com/setup-gui-for-amazon-ec2-linux/
http://www.comtechies.com/2013/02/how-to-set-up-gui-on-amazon-ec2-ubuntu.html
Hope it helps!
You can install a GUI just using one command
sudo amazon-linux-extras install mate-desktop1.x
I'm using a Remmina VNC as a client on my Ubuntu.
If you need a Windows client - then you have a plenty of options - RealVNC, TightVNC, TigerVNC, UltraVNC
I am having trouble getting an x11 window of the desktop of a remote machine.
I am VPN'ed into a local network and I can get into the computer I want through the command line using:
ssh -X computer_name -l login_name
I thought that the -X would cause the remote machine's desktop to pop up in x11, and although x11 launched on my mac, I did not get an x11 window of the machines desktop.
I can get things like emacs to run and pop up in new x11 windows, but I want to get the whole desktop going.
I am running Mac OS 10.7, and the remote machine is running linux.
Any help would be appreciated.
Figured it out.
after the command
ssh -X computer_name -l login_name
I had to start a gnome-session
gnome-session >&/dev/null &
this gave me the linux desktop in an x11 window.
ssh -X (or -Y) only tunnels the connection to your local X server for the applications started on the remote machine from your SSH session. It cannot do anything about the desktop environment that is running on the remote machine's own X server.
You're probably looking for something like VNC, not X11 forwarding.
X-Window allows you to run programs remotely, and have their windows appear locally on your machine. As you stated, you were able to get this working properly. If you want to see the entire linux desktop on your mac, you will want to use a program like VNC.
You will need to run vncserver on your linux machine, then you can use any of a number of VNC clients on your mac to see the entire linux desktop. For example, Chicken of the VNC.
If you want your remote Linux desktop to be displayed on a window on your Mac you should use on your Mac (providing that the VPN is already setup and running, you have access to your Linux server, and XDMCP is configured on it):
$ Xephyr -query <linux-ip-or-name> :1
