I have yet another tweak to propose for Lite Tweaks collection; Kiosk Mode. Something basic to allow administrators to disable the options to Shutdown, Restart, Suspend and Hibernate the computer for regular users accounts.

Cases where this might be convenient:

In my own experience, my wife decided to shutdown a VM where I was developing and testing few things that I didn't save before stepping away from it. You can imagine my surprise when I came back  and found out that the VM was off and I hadn't saved my messy work :o

She was actually using her own account and not mine so she didn't "see" I was actually working on that VM. To prevent that from happening again (because she uses the same VM I use since I like to hear from her feedback - our VMs are hosted and shared in a VMWare Hypervisor on the network), I disabled her ability to shutdown, restart, Suspend or Hibernate the machine... something similar to this:







While it doesn't fully prevent users from shutting down (e.g: user can force a reboot using the Terminal), at first sight the option isn't really available to restart the machine. I have to research how we can fully prevent regular users from shutting down even from terminal. I've done so in the past with Ubuntu polkit but I don't remember out of the top of my head how to do it.

Hi Jerry,

This is where it is so far:

Settings by default:



Kiosk Mode Enable for all users and power options disable on logon screen





I'm considering changing "Enable or Disable Kiosk Mode" title to "Kiosk Mode Options"

Also, I'm removing the column header else the Power options will get scrambled if the user clicks them to reorganize columns.

More like this:

I prefer the inner title to be " Kiosk Mode Options' and to keep the column titles. Therefore, a mix of image 1 & 2 if that makes sense.

The problem with the header title is that if clicked it will scramble all the options around cos' it organizes it alphabetically... that's why I removed it.

Thanks for the explanation. Go forth :)

Ok Jerry, I think I the functionality is there already... ready to push it to master?

[valtam]

Go for it. Would be cool to announce this for 3.4 :)

Indeed, we have Kiosk Mode and zRAM so that's 2 additional tweaks that makes it to Lite Tweaks. Pushing it in a bit as follow in Lite Tweaks:

Kiosk Settings - Administration - System - (description here)

But I'm concerned about these options Jerry. See, there is no explanation about what they do and what they don't do. For example, these settings do not turn the machine into a complete Kiosk. It does allows admins from disabling the shutdown and reboot options plus enabling or disabling the power options on the login screen. We should have a place where that is explained so that users can know what the tweak does instead of having them figure out what changes when the tweak is enabled.

How should we address that?
