Hi there everyone!
I've just started to write a tool to view opengl support status of a linux box. Its called GL-Status. Its licensed under GPL. Sourceforge project site follows:
Qt for gui
SDL for opengl context creation
and of course OpenGL
Its currently in a very early stage of development. At this moment feedbacks from the community are important for the future. So feel free to leave your comments either to this thread, or to email@example.com, or if you have a sourceforge account you can review it. Also feel free to contribute bug fixes etc. Thanks.
