Want to protect from accidentally invoking power-off commands, or prevent multi-user or public use computers from being shutdown or restart by non-admin users? This tutorial may help by either hiding the power-off menu or adding password request.

Hide Power-off Menu (for GNOME only)<\/h3>\n

\"\"<\/a><\/p>\n

For Ubuntu and other Linux with GNOME desktop, there’s an extension can do the job by hiding action buttons from top-right system menu (aka Quick Settings).<\/p>\n

First, search & install “Extension Manager<\/b>” (filtered by Debian package) from App Center (or Ubuntu Software for 22.04).<\/p>\n

\"\"<\/a><\/p>\n

Then, launch the tool and navigate to Browse<\/b> tab. Finally, search and click install Bring Out Submenu Of Power Off Button<\/i> extension. It so far supports GNOME from v3.36 to 48.<\/p>\n

\"\"<\/a><\/p>\n

As the name says, the extension is designed to bring out power-off sub-menu options, which also has toggle options to hide actions that you don’t want.<\/p>\n

Also in Extension Manager, switch back to Installed<\/b> tab, and click on gear icon for the newly installed extension. In the pop-up preferences dialog, turn on the options to hide what you want!<\/p>\n

\"\"<\/a><\/p>\n

For Ubuntu 20.04<\/b> and other Linux with GNOME, go to the page below, then use ON\/OFF toggle to install the extension:<\/p>\n

\n
Bring out PowerOff Sub-menu<\/a><\/div>\n<\/div>\n

NOTE:<\/b> If it asks, you need to click the link in that page to install browser extension and refresh. And, Debian\/Ubuntu users need to run command in terminal (Ctrl+Alt+T) first to install agent package:<\/p>\n

sudo apt install chrome-gnome-shell<\/pre>\n
\"\"<\/a><\/p>\n
For Ubuntu 20.04, there’s NO extension manager, instead search & install “Gnome Extensions<\/b>” to configure extensions, or run the command below in terminal to get it:<\/p>\n
sudo apt install gnome-shell-extension-prefs<\/pre>\n
Enable Password Request for Power-off \/ Reboot Actions<\/h3>\n
For most Linux, there’s built-in polkit (formerly PolicyKit) tool available to control system-wide privileges. By adding polkit rules, you can control permissions for many system actions.<\/p>\n
NOTE: for Ubuntu 22.04 and earlier, scroll down and use the old method!<\/b><\/p>\n
1.<\/b> First, press Ctrl+Alt+T<\/code> on keyboard to open terminal. When it opens, run command to add a custom polkit configuration file then edit via nano:<\/p>\n
sudo nano \/etc\/polkit-1\/rules.d\/10-power-off.rules<\/pre>\n
Here I use nano<\/code> command line text editor that works in most Linux.<\/p>\n
2.<\/b> When it opens, copy and paste the lines below:<\/p>\n
polkit.addRule(function(action, subject) {\r\n    if (action.id == \"org.freedesktop.login1.power-off\" ||\r\n        action.id == \"org.freedesktop.login1.power-off-ignore-inhibit\" ||\r\n        action.id == \"org.freedesktop.login1.power-off-multiple-sessions\")\r\n    {\r\n        return polkit.Result.AUTH_ADMIN;\r\n    }\r\n});<\/pre>\n
The lines above added a rule when any user trying to do any one of the following actions (“||<\/b>” means OR<\/b>):<\/p>\n
