Well.. it worked putting it in a script file. But now... how to automatically run it?
I inserted it in the gnome sessions... all the switcheroo commands are executed (modprobe, insmod, etc..) , but not the echo command, so the discrete card doesn't switch off automatically... Then I tried inserting it as init.d and doing update-rc.d .. but when I restart the system hangs! Then ... I would like to echo ON on the switch file just before shutting down...because if I shut down without doing it the system hangs and doesn't shut down. Any suggestion?
