X-Windows-Server won't Start (Acronis True image Server for Linux)

everytime i want to run "trueimage" i get the following error:

SERVER:~# trueimage
Error: failed to open the display :0.0
Please, check the DISPLAY environment variable or use the -display option.
Aborted.

 

i forgot: I try to run this at an DELL PowerEdge 750 over SSH (putty)

 

Hello Iceage,

Thank you for choosing Acronis Linux Server Disk Backup Software.

Please try to launch Acronis True Image with the following command:

trueimage --safe

If the problem persists please check what processes use your X-server. There should be no problem if you reboot the computer and then launch Acronis True Image Server for Linux once again.

Thank you.

Just to be clear... You are doing this:

Code:

+--------------+                      +---------------+
| PC with SSH- |                      | SERVER with   |
| client and   | <--- SSH-tunnel ---> | True Image as |
| X11-server   |                      | X11-client    |
+´-------------+                      +---------------+

In that case the X11-display on the SERVER is not likely to be called :0.0, since that would indicate a local X11-server. I would expect the display to be called something like SERVER:10.0

Are you sure you are forwarding your X11-server from the PC over the SSH-tunnel?

When you login to SERVER, are you then logged in directly as root, or as yourself? If you are logged in as yourself, what is the result of echo $DISPLAY?

Can you start a simple X11-application like /usr/X11/bin/xclock and have it show up on the PC?
