<div>Dear Sylvestre,</div><div><br></div><div>Are the configuration problems that you are referring to, connected with the SSH configuration or graphics drivers' ones?</div><div><br></div><div>You said that it worked on your set-up. Can you share whether you also have an NVIDIA graphics card/drivers on your local PC? As you mentioned that it can be a configuration problem, I am wondering whether I need to install on my PC, the same drivers as on the server for graphics? The one that I have now is the INTEL graphics driver and the server has NVIDIA. As I mentioned earlier, Scilab is perfectly working if I sit on the server and work.</div>
<div><br></div><div>If the issues are connected with SSH configuration, does anyone have any suggestions where I can find some resources to fix this problem.</div><div><br></div><div>Thank you very much for all your assistance.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Looks like a configuration problem on your side. I just tested to start<br>
Scilab this way and it works.<br>
<br>
You can try to force software acceleration if it fixes your graphic<br>
issues with intel:<br>
system_setproperty("jogl.gljpanel.nohw","");<br>
