I know this is a LWJGL error but do you have any idea?
Thanks

When does this happen? Only when using the AWTGL-stuff or with a native OpenGL window too?

hello,
My app runs a AWTGLCanvas... I didn t try with something else... What i suspect is that maybe an openGL driver for the video card is missing. I contacted the administrator of my univ and he was unable to answer me :?
I will check with a friend of mine who frequently deals with MESA on similar computers at my univ. And i will come back to you once i will have the answer.
I think it must be a crappy thing somewhere in my config...

Just to say that this error is due to the fact that the computer simply doesn t support direct rendering (as seen when using glxinfo command).

Ciao

Try using new LWJGL 0.99 - i saw there were lots of bugfixes, some of them related to awtgl. I also have problems with awtgl on some videocards, and i hope to check out if 0.99 helped to solve them today
