OpenGL error while using Processing

Whenever I try to use 3D graphics in Processing 2.0.1, like this:

void setup() {
size(640, 360, P3D);
fill(204);
}

void draw() {
lights();
background(0);

camera(30.0, mouseY, 220.0,
   0.0, 0.0, 0.0, 
   0.0, 1.0, 0.0);

noStroke();
box(90);
stroke(255);
line(-100, 0, 0, 100, 0, 0);
line(0, -100, 0, 0, 100, 0);
line(0, 0, -100, 0, 0, 100);
}

...I get an OpenGL error. Here is the console output (I'm using Sublime Text 2 rather than the Processing IDE):

Listening for transport dt_socket at address: 8213
OpenGL error 1280 at bot beginDraw(): invalid enumerant
OpenGL error 1280 at bot endDraw(): invalid enumerant
OpenGL error 1282 at bot endDraw(): invalid operation
X11Util.Display: Shutdown (JVM shutdown: true, open (no close attempt): 1/1, reusable     (open, marked uncloseable): 0, pending (open in creation order): 1)
X11Util: Open X11 Display Connections: 1
X11Util: Open[0]: NamedX11Display[:0, 0xae31248, refCount 1, unCloseable false]
Finished.
[Finished in 28.6s]

However, I do seem to have OpenGL (and it must be working otherwise because WebGL functions OK.) :

laura@drukqs ~ $ lspci | grep VGA
00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Wrestler [Radeon   HD 6290]
laura@drukqs ~ $ glxinfo | grep OpenGL
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD PALM
OpenGL version string: 3.0 Mesa 9.1.3
OpenGL shading language version string: 1.30
OpenGL extensions:

I am using Linux Mint 15 on an Acer Aspire One 722, and I doubt my graphics driver is that great, but that can't be the problem, can it? Because like I said, WebGL does work.

EDIT: It also doesn't work in the Processing IDE, or on the Examples page on the Processing website.

OK, it looks like the simple solution was to use the proprietary graphics driver...of course my computer has other problems with P3D, but that's a post for another day.

Eclipse does not find the needed library for using OpenGL (which P3D uses). You have to import these files as described in this post.
