I've been using JOGL 1.1.1a on Ubuntu for some time and setting sun.java2d.opengl=True to improve performance for applications using GLJPanel.  Everything has been working smoothly until I updated to Ubuntu 10.10 which includes the new Nvidia driver version 260.19.06 (Ubuntu 10.04 used 195.36.15, which worked great).

With Ubuntu 10.10 and the Nvidia 260.19.06 and sun.java2d.opengl=True I see the following problems:

1. Nothing is visibly drawn in GLJPanels.
2. If I turn on jogl.debug I get this warning: X11ExternalGLDrawable: WARNING: forcing GLX_RGBA_TYPE for newly created contexts.
3. X often crashes with a segmentation fault when the java application exits:

Backtrace:

With Nvidia 260.19.06 and sun.java2d.opengl=false, I see things being drawn correctly in GLJPanels.  However I still often see the X segmentation fault when the java application exits (#3 above).


Ubuntu 10.10 also gives me the option to install version 173.14.28 of the Nvidia drivers.  Using this version, things work perfectly with sun.java2d.opengl=True or sun.java2d.opengl=false.  I do not see any warning from X11ExternalGLDrawable.


So it appears I have a workaround for the moment in using older Nvidia 173.14.28 drivers, but I am a bit nervous that things are broken with the newer drivers.  Has anyone else seen problems with Nvidia 260.xx drivers?
