Fwd: Re: [Gate-users] Remote Visualization Problem

Hello Xiao, 

I just tried out the visualization via VNC over the network. I have on both 
machines Debian Unstable installed. Both use XOrg 7.1. The remote machine has 
the ATI OpenGL drivers installed, the local machine has the XOrg Radeon 
drivers installed. 

As a VNC server I start x11vnc v.0.8.2 on the remote machine using the 
following command from the local machine: 

ssh -L 5901: 'x11vnc -localhost -display :0'

As a VNC client I start TightVNC viewer v.1.2.9 on the local machine using the 
following command: 

vncviewer -encodings "copyrect tight zrle hextile"

Remote controlling my GATE simulation machine this way, I can get the OpenGL 
visualization to work just fine. It might be a bit sluggish though. 

I just tried exporting the visualization window onto the local desktop with 
only little success. It managed to completely freeze my Desktop. 

I hope this will help you to get things to work.

Hi Christian,

That's a good idea! I'm gonna have a try. Please keep me
posted about your result, too.
