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 --
