How to start X program on local display?

Question

I'm ssh-ing into a Raspberry Pi. I would like to start an X program remotely, on the Pi's display.

I know you can export DISPLAY to have programs open up on your computer when you ssh-in. But I'm looking for the opposite.

What I'd like to have is have a program open up on the Pi's own (HDMI connected) display, when I run a command from ssh.

What I'm looking for is to have a program run on the Pi and display it on the Pi. Pretty much I'd like to just remote control the Pi, using my desktop's keyboard.

I'm on Raspbian / Deb Wheezy.

Solution

Just run xeyes on the PI (check that you have env variable DISPLAY setup export DISPLAY=:0.0 or specify it directly

xeyes -display ':0.0'

That should be the default behavior unless you are using the -X or -Y options to ssh in. Doesn't it work? Do you get an error?

Yes, my error is like Error: Can't open display: (null) Failed creating new xdo instance. I'm just using normal ssh to log-in, not -X or -Y

You need to set DISPLAY=:0 and to configure xauth.

I guess this runs a program on my desktop and displays it on the Pi. What I'm looking for is to have a program run on the Pi and display it on the Pi. Pretty much I'd like to just remote control the Pi, using my desktop's keyboard.

Arh sorry, misunderstood, when you said opposite. Just run xeyes on the PI (check that you have env variable DISPLAY setup export DISPLAY=:0.0
