Hi,
Sorry, I used Joss script to switch the states (thanks fot that!). The 
test.sh didn't work for me too.

Btw, vga_switcheroo works on my hardware! I can switch the cards and 
their outputs. But it has a strange behaviour: it works only after the 
Kernel version is switched! How can that be? I tried different Ubuntu 
Kernels and some mainline Kernels. The first time I boot a new Kernel 
the /sys/kernel/debug/vgaswitcheroo/switch file is there, after the 
first reboot it simply disappears! Then if I switch to an other Kernel 
using Grub it appears again, but only until I reboot with the same 
Kernel. How can that be explained?
