I have been looking around but not found a script that handles total offline/powersave mode. I.e. just let's the gsm to be on. Such a script would be great for alarmed. I am not sure but think unloading kernel modules might be the best way? So software can't enable it. * Switch of internet * Switch of bluetooth * Switch to only GSM mode * Set the screen light to minimum And a script to enable normal again. Does somebody have a script like this?
