[openvrml-develop] lookat does not show wrl image, but copies X-background on debian-etch system with sis630.

[Hans De J. <j.d...@gm...>]

Hi

Although I developed quite some linux tweaking experience in the last
eight years, I cannot get any vrml-viewer to display vrml-data in a
window on my screen. (I need to display the shape of the fermi surface
of tungsten to get an idea of the electron trajectories in strong
magnetic fields in a solid state physics experiment)
Since I use a debian system I did not use the fedora-core rpm but
compiled freewrl from the tar-ball which succeeded after installing
some new develpment packages.

Upon running the application though, I get a window; the image of the
desktop content underneath it (usually part of the xterminal-window)
is copied into the window and this image is dragged along with the
window, instead of it showing the wrl picture.

The same thing happens with freevrml, octagoFreePlayer and Orbisnap,
so I suspect it is not a typical openvrml problem, but since you must
have more knowledge in these matters like XFree86 topics I hope
someone can help me solving this problem or give pointers to the
documentation I was not able to find.

Some more information:

My graphics chip is an sis630, connected to my laptop LCD-screen
X Window System Version 6.8.2 (Debian 6.8.2.dfsg.1-7 20050908031534
David Nusinow <dnu...@de...>)
Home-built linux kernel 2.6.13.4 to which I applied the win4lin patch
sun-j2sdk1.5 and sun-j2re1.5 debianised installed
Blackdown java3D (sdk)

further:
Although my Xorg.0.log logfile contans the message:

(WW) Ignoring request to load module GLcore

on line 155, I suspect GLcore is loaded judging from the lines 218-227
furtheron:

(II) Loading sub module "GLcore"
(II) LoadModule: "GLcore"
(II) Loading /usr/X11R6/lib/modules/extensions/libGLcore.a

        compiled for 6.8.2, module version =3D 1.0.0
        ABI class: X.Org Server Extension, version 0.2
(II) Loading extension GLX

when I shut down the openvrml window I get a message:

[hansdej@rolfie]~>lookat test.wrl
freeglut  ERROR:  Function <glutDestroyWindow> called without first
calling 'glutInit'.
[hansdej@rolfie]~>

I would be gratefull if anyone of you could help me getting a wrl
viewer runnning since I do not know where to look anymore.
