I'm trying to build and start Opengl es example from PowerVR SDK on scratchbox x86 (fermantle). From wiki article about Opengl es and maemo:
"The SDK libs and headers can be dropped into your X86 environment and run into the Xephyr X11 window - but you'll need to kill the window manager first! "

What does this words mean "but you'll need to kill the window manager first"? How can I kill the windows manager?
