Cannot start SDK under Arch Linux

I have downloaded the Alpha 4 version of the SDK and installed it into my home directory. When trying to run it, I get the “error opening OpenGL window! Your graphics card needs to support at least OpenGL 2.0” Error message. I am unable to click the OK button and close the dialogs.

My graphics card is a Radeon 5870, and I know that 3D is working. I’ve tried updating to the latest driver, but that doesn’t help.

What can I do to avoid this problem? I have found a few other threads about this problem, but none containing a working solution. I’d really like to get started with using JMonkeyEngine.

Look for the release blog-post for alpha-3, its comments contain information on how to disable the welcome screen by editing a properties file.
