<div dir="ltr"><br><div class="gmail_quote"><div dir="ltr"><div><div>Hi,<br><br></div>I have an ubuntu 12 running in a VirtualBox. Scilab is unable to plot any simple graph (Im testing with "plot(1,1)"). The graph window appears completly black and it stops responding.<br>

</div>I found some posts about this problem, and I already tried several things but nothing fixed my installation. <br>It would be awsome if some can give me a hint to try to solve the issue as Im stuck now. Below you can find all the details of the environment and the things I already tried.<br>

<div><br>Thanks!!<br><br><b>Environment</b><br>The host OS is a windows 8, with a VirtualBox 4.3.6. Im running Ubuntu 12 and Scilab 5.3.3 (I can not use another version of Scilab as it is linked to another software).<br>
</div>
<div>I already reinstall the lastest VirtualMachine Additions and enabled 3D acceleration.<br></div><div>Without 3D acceleration scilab is able to graph but Ubuntu run really sloooooowww.<br></div><div><br></div><div><b>The problem<br>

</b></div><div><b>1) </b>plot (1,1)<br></div><div>When I execute "plot(1, 1)" I get the following error and a black graphic window (debug info at the end):<br><div><div style="margin-left:40px">!--error 999 <br>

A native error occurred during the drawing of the figure.<br>Description: Illegally formatted version identifier: "null"<br>...... <br></div><br></div><div><b>2)</b> I tried using "system_setproperty("jogl.gljpanel.nohw","");"<br>

</div><div>But I get exacly the same problem<br><br></div><div><b>3) </b>With usecanvas(%f) I get a different error (debug info also at the end):<br><div style="margin-left:40px">->plot(1,1)<br>Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: Unable to select one of the provided GLCapabilities<br>

4) Disabling 3D Aceleration from virtualBox solves the issue but makes ubuntu run too slow.<br></div><div><div style="margin-left:40px"><br></div></div><div><br><b>debug info with usecanvas(%t)</b><br>-->[a,b]=getdebuginfo()<br>
