OpenGL - error

Yes fullscreen logo on white background I have some experience with installing nvidia and ati drivers in linux.

I can run opengl, enemy territory etc, quake 4, and so on.
"Driver" is set to "nvidia" in the XF86config (Xorg) config file, not "nv".

I was using the sourcecode from http://www.blitzbasic.com/Community/posts.php?topic=42662 (I replaced the old stuff with the new ones (GLGraphics, etc)).

This works:

GLGraphics(800,600)
init()

While Not KeyDown(KEY_ESCAPE)
display()
Flip
Wend 
End

Function init()
glClearColor(0.0, 0.0, 0.0, 0.0)
glColor3f(0.0, 0.0, 1.0)
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
gluPerspective(45.0, 800/600, 0.1, 100.0)
End Function

Function display()
glClear (GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
glBegin(GL_TRIANGLES)
glVertex3f( 0.0, 1.0,-10.0)
glVertex3f(-1.0,-1.0,-10.0)
glVertex3f( 1.0,-1.0,-10.0)
glEnd()
End Function

This does not work in linux for me, it gave me the "major opcode GLX" error, but after replacing the GLgraphics line with "GLGraphics(GW,GH)" It now gives me a "appstub.linux signal handler 11" and the whole ide halts (although the same code works in win32):
