To get the vgaswitcheroo debugfs entry you need to have a handler
(asus-switcheroo) and two clients (i915 and nouveau/dummy-client).  If
you turn off modeset on i915, it won't register as a client.  If
nouveau doesn't load (won't load with nvidia kernel module loaded), it
won't register a client.  asus-switcheroo won't register a client w/o
the dummy-client=1 option.  So, make sure you're not disabling the
i915 modeset, and either allow nouveau to load (by not loading the
proprietary nvidia kernel module) OR use the asus-switcheroo
dummy-client.  Thanks,

Alex
