PROBLEM DESCRIPTION

When you launch an X application, you get the following error message and the application fails to start:

Xlib: extension "GLX" missing on display


RESOLUTION

This problem may occur when the X application requires OpenGL support. 


Also, you can try disabling the 3D feature on the X application. There are some X applications that support both OpenGL and non-OpenGL based 3D mode. However, this option is application dependent and your application may not have this option. Also, using non-OpenGL mode may slow down the application performance. For more information, refer to the X application manual.


Note

For example, I-DEAS users can use "-dX3D" parameter when launching the application to disable OpenGL use. Application will still show 3D images.
