After reading https://help.ubuntu.com/community/HybridGraphics,
the vga_switcheroo thing is enabled:

$ grep -i switcheroo /boot/config-2.6.35...
CONFIG_VGA_SWITCHEROO=y

but the file /sys/kernel/debug/vgaswitcheroo/switch doesn't exist, nor even the dir vgaswitcheroo...
(I'm running Kubuntu 10.10)

Do I need to do something else to make it appear?
