Thanks for checking it out!
A relatively sane reason for this behavior is that the GL context is not 
created, somehow. glGetString could theoretically return null if it's 
called within glBegin .. glEnd, but this is not the case.

Thanks! I'll look at it.

Well, it should work well with Mesa. At least it works for me, in the 
Debian Etch I've got set up in VMWare Player.

:o Hrm, this doesn't look too good, I'll pass the info to Ralith / 
Benjamin who's created the GLX backend. Such an error should cause it to 
crash on his GDC under FreeBSD and my VM'd debian... Weird.

Thanks a lot for testing and finding it out :)

It appears that it's used for changing display modes for fullscreen 
support, tho I'm sure Ralith would be able to give you more info :}
