I want to disable all features on a specific user, on my Ubuntu 15.10. I want him to:

  • Don't change the wallpaper

  • Don't let then do anything on the computer, not saving files, not surfing on the directories, not executing any type of program (only the navigator)...

  • Make the navigator automatically launch, with a specific home that cant be changed. Either dont let then navigate in other pages.

  • Let a custom script (that has the usbip start + bind) execute every time the system loads.

I need to have access to all features in an admin account.

I've created a custom user, and with sudo nautilus I disabled access to all the / directory. The system crashed, so I only let him his /home/thenameoftheuser directory. It crashes too.

    And what do you expect from us? – Jacob Vlijm Apr 4 '16 at 8:31
  • Any type of help. For example, where is the "gnome-appearence..." on ubuntu 15.10? – kek Apr 4 '16 at 8:34
  • BTW, sudo + GUI is a bad idea: askubuntu.com/questions/270006/… – Jacob Vlijm Apr 4 '16 at 8:35
  • Didn't know about that, tought typing sudo was like excuting as admin, won't do it again. – kek Apr 4 '16 at 8:41
  • Wallpaper changing can be sort of restricted with putting a function that keeps on setting the wall paper (basically infinite loop). Navigation to other directories is a bit more problematic - there's almost no way to restrict that – Sergiy Kolodyazhnyy Apr 5 '16 at 0:59

That's easy! It's called the guest session!

Just give that particular user a USB stick to save their files to and you've got picture-perfect isolation without any additional work!

If that's not restrictive enough, you can customise the guest session with all of your requirements...


  • How can I enable the guest sesion on a live Ubuntu? – kek Apr 5 '16 at 10:24
