    Superuser on/off with a single click?

    Being a long term Linux (Ubuntu) user, I hve grown accustomed to the ability to access SuperUser privileges from a terminal.

    My question; is it possible to activate su from a terminal emulator app, do what one has to do, and then simply exit from the terminal and everything is back to square one?

    If you have root enabled on your tablet (achieved through a variety of methods) you can install a terminal emulator app. This app will ask for the root permission access as soon as you launch it and you can grant it forever, one time only or an interval of time in the popup permission window. That's how all root apps work within Android.

    If you choose to remove access altogether there are functions within the superuser app (which controls all root access) to do a temporary unroot or a permanent unroot. I hope that answers your question.

    Until just now I've never tried that exact thing on my 701, never had to. But it is rooted and has a terminal emulator (both come with the custom ROM Zombi-Pop that I'm using).

    You can install and use a terminal emulator on a non-rooted system, but you can't do much with it, it's easier to just use the GUI apps. But if you want to access the system files, you must be rooted. So what actually happened is that I opened the terminal without incident, no notification from SuperSU (the superuser access control app I'm using). But as soon as I entered "su", up pops the SuperSU dialog box asking if I want to allow the terminal emulator root access. I touched the "Grant" button; from now on SuperSU will grant root access to terminal whenever it requests it, unless I change that in SuperSU settings. The logon changes from "u0_a29@tf701t" to "root@tf701t". To exit from root privileges, well, you guessed it--enter "exit". Entering "exit" a second time closes Terminal.

    If you are familiar with Linux command-line, you will have no trouble with Android command-line. It is not only similar, it is exactly the same; Android uses the same BASH shell as Linux, including Busybox if it's installed on the system (it usually is, although some manufacturers strip it down). Many consider Android as just another distro of Linux. The main difference that I see is that while most Linux distros will allow separate partitions for /system, /data, etc., Android insists on it.

    Get a little more prose than you bargained for? Sorry but we all hope you enjoy your 701.

    Not the way I read it, Spinner just wanted to know if he could do that particular thing. If he is actually interested in installing Ubuntu on the tablet, while it should be possible, I don't recommend it--I have yet to read of a truly successful attempt. People have problems with drivers, usually touchscreen, display and wi-fi. I recently read of an installation of Linux Mint on a 301 that sort-of worked, but ran so slow it was unuseable. LM is based on Ubuntu.

    Hey, we might as well be good for something! How did the old saying go, something about those that can't do, teach?
