Cool. Nice to see I was wrong when I said that (hardware accelerated)
OpenGL under Linux is limited to X11.
I really doubt any of those solutions work on nVidia hardware though.
Which is what most people playing games under Linux have.
And X11 isn't THAT bad anyway. Creating a window from the lowest-level
API is basically just as complicated under Windows. But with GUI
toolkits and SDL, who needs to do that anyway?
