I use Ubuntu to make a kinda hotSpot (wifi).

I dont want anyone (thief or hacker) to be able to navigate into the system by pluggin-in keyboard-mouse-screen. (Unless me or my collaborators). At boot my system is not running root, but just a standard user.

I think about using Ubuntu server distro, but I really need Desktop. However it would be great to see only a fullscreen image, above the desktop, displayed from boot. Entering desktop mode (or disabling the image layer) could be done by making a secret key combination, for instance, or by clicking a corner of the image...

My question is: Is there a way, from an Ubuntu desktop distribution,to avoid landing on the desktop by displaying a fullscreen icon instead ?

Thank you --

  • All can be done, but: silly question, but locking the screen is no (sufficient) option? – Jacob Vlijm Aug 12 '15 at 17:57
  • This is... right. – 3pic Aug 12 '15 at 17:58
  • Do you mean it is sufficient, or it isn't ? :) – Jacob Vlijm Aug 12 '15 at 18:00
  • Sufficient I guess. Yes it is. But locked screen asking for password ? – 3pic Aug 12 '15 at 18:02
  • If your account is set to access with password, yes. If it is sufficient, would you mind if I posted it as an answer? I would be happy to help you from the zero- accepted record :) (so far, you haven't been very lucky on AU :) ) – Jacob Vlijm Aug 12 '15 at 18:04

If a system is really completely unattended, preventing a hacker from accessing your system is practically impossible (only think of simply restarting the system from an external medium).

Having said that, what you describe can be done with a background script, but it already exists in the form of... Lockscreen :)

Simply Press Ctrl+Alt+Delete, and click the lock symbol.

The solution assumes you set a password to your account (can be done with a "normal" user account).

  • Actually, my FS is LUKS-encrypted ;) And keyfile is on a USB pendrive. I want to prevent from the case I leave the USB pluggedin while I'm on the toilet ;) BUT the more important, I d like to have a lockscreen at Launch, no manual thing to do. – 3pic Aug 12 '15 at 18:23
