How to launch a GUI application on a BeagleBone that is running Linux (Debian 7.4) remotely?

Notes:

1. putty is being used for the remote access.


2. The task is to have the GUI launched and displayed on the BeagleBone itself (i.e., no X11 forwarding)

You need to set the DISPLAY variable after you have logged in using PuTTY:

export DISPLAY=":0"

Then you should be able to start an GUI application like xclock

Note: You need to login using PuTTY as the user who has a running desktop environment.

Confirm your regular value for the DISPLAY variable from a desktop session on the BeagleBone itself using a terminal issuing export|grep DISPLAY

No X11 forwarding is necessary when you use PuTTY to connect from another host.

To start such GUI process in the background use:

export DISPLAY=":0"
xclock &

If the commands needs to be run as root, it might be necessary to set an additional environment variable in the ssh session:

export XAUTHORITY=/home/user/.Xauthority
su -c xclock &

And it may even take a change to the sudo configuration if you want to use sudo to launch the application:

visudo
Defaults env_keep+=XAUTHORITY
sudo xclock &

  Are you trying to start X over a ssh connection? Did you find and read x.org/wiki/FAQErrorMessages/#index5h2. My answer assumed that you have a working GUI desktop and you just want to open another application to be displayed on the GUI desktop.
