Hello Matias,<br>
<br>
It may be driver-related. Try to check your install, notably by
making tests on your host.<br>
<br>
Or maybe you could test a Scilab 5.4.1 to see if it is a Scilab
version problem.<br>
<br>
Hope this helps,<br>
Cordially,<br>
Paul.<br>

<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>

</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"

4) Disabling 3D Aceleration from virtualBox solves the
issue but makes ubuntu run too slow.<br>
