Could not create a direct GLX context

[jglover13]

Guys,

Eventually I will be posting intelligent answers to other people's silly questions, but for now I'm still in beginner-land.

I'm having an issue getting the library to work on my linux system.  It's a laptop, but it does have a 8MB Rage Mobility 3d card.  I can run glxgears just fine at 78 fps (this will probably only make sense to Linux users).  

Unfortunately, I get the following error when trying to run any code that uses the library (specifically my Lesson10 which has been updated to the newest version of lwjgl):

Current mode 1024 x 768 x 24 @0hz
org.lwjgl.LWJGLException: Could not create a direct GLX context
     at org.lwjgl.opengl.Display.createContext(Native Method)
     at org.lwjgl.opengl.Display.create(Unknown Source)
     at Lesson10.createWindow(Lesson10.java:273)
     at Lesson10.init(Lesson10.java:279)
     at Lesson10.run(Lesson10.java:91)
     at Lesson10.main(Lesson10.java.86)

I get the same error when I try to run the window creation test with version 0.9a of the library.  It did, however, find 15 display modes.

Do any of you Linux smarties have an idea where I would start to look to fix the problem?  I'm sure it is not a problem with LWJGL; it is a problem with my 3d display or system setup.

Some graphics cards cannot display 24bit colour.  Try a different display mode.  It is usually safe to start with 640 x 480 x 16.  You should also list the display modes that is says are available and use one of those.
