Thanks a lot.
But I found another problem regarding mouse and xinerama:
OpenGL games like cube or vegastrike don't handle mouse events when 
xinerama is enabled. Without everything works fine.
It seems like factor 100000 too fast mouse reports with your patch, 
without that mipointer patch no mouse movement gets recognized at all.
It doesn't make any difference when I start cube windowed or fullscreen.
Any idea?

Best regards,
