pbuffer with X11...

[dr-grim]

Hi all,

I've been trying the various JOGL demos to test the pbuffer support under X11 - under Linux, AFAIK, the hwShadowmapsSimple should work.

but... just a blank window appears, no textual output. If I run (e.g.) the gears demo, it works a treat, and I get:

[jogl-demos]$ java -classpath ../jogl/build/jogl.jar:.  -Djava.library.path=../jogl/build/obj demos/gears/Gears

CANVAS GL IS: net.java.games.jogl.impl.x11.X11GLImpl
CANVAS GLU IS: net.java.games.jogl.impl.GLUImpl
INIT GL IS: net.java.games.jogl.impl.x11.X11GLImpl

GL_RENDERER: GeForce4 420 Go/AGP/SSE2

glLoadTransposeMatrixfARB() supported: true

Similar results seen with Solaris build (i.e. shadow mapping demo fails to produce anything, gears works fine). Any advice greatly appreciated. I'm looking to use pbuffers for off-screen rendering...

Cheers,
