System Settings can be run from the launcher (pinned by default), the Dash, or the power cog. But what command would I enter in a terminal window if I want to run it from there?

For versions between 14.04 and 17.04 :

unity-control-center

For versions before 14.04 & 17.10 and greater :

gnome-control-center
  • FYI, on my Ubuntu 14.04 only gnome-control-center works. – dr01 Dec 17 '15 at 14:00
  • @dr01 I assume you are running the Gnome DE and not Unity DE then. – Elder Geek Jul 17 '18 at 15:22
  • You can still install the unity-control-center on newer versions (17.10+) if you don't like the newer gnome-control-center – mchid Apr 9 at 0:02

if you run

gnome-control-center

and get

gnome-control-center: command not found

you can install with

sudo apt-get install gnome-control-center

For Ubuntu Mate the command is mate-control-center.

I found a different solution...

  1. I tried removing/installing gnome-control-center; this did reinstall the application I still couldn't open it.

  2. Later I found that it would start up on the side of the screen and I couldn't access it

  3. I changed the display mode to single display and it came back. Hope it helps.

In Crouton, you must run anything that would require a password from the terminal, such as update manager, software center, synaptic, etc. So, to get to system settings you would enter in the terminal:

sudo gnome-control-center

That will bring up the system settings GUI.

To check for updates, or if the update manager appears in the Unity Launcher, run it from the terminal, not by clicking on it:

sudo update-manager

The same applies to synaptic, the software center, etc. Anything which requires a password, must be run from the terminal in Crouton with a sudo.

Well, in KDE NEON 5.16.4 (Ubuntu 18.04), it is written in the "System Settings Handbook":

The System Settings can be started in one of three ways:

  • By selecting Settings → System Settings from the Application Menu.
  • By pressing Alt+F2 or Alt+Space. This will bring up the KRunner dialog. Type systemsettings5, and press Enter.
  • Type systemsettings5 & at any command prompt. All three of these methods are equivalent, and produce the same result.

In my case, I needed to configure my HP LaserJet settings. Doing this as user, after applying and saving, they were ignored. So I think I had to do this as root and the settings are stored normaly now, so, each time the user opens the print dialog, the system remembers that I want log side binding and 1200 resolution :=)

I thought that sudo systemsettings5 & was enough, but as Zanna suggests: It should also be recommended to use 'sudo -H' if opening a GUI app with sudo.

  • Why do we need sudo here? It seems like a bad idea to unnecessarily run a GUI application as root, especially using plain sudo which in most versions of Ubuntu could cause config files in a user's home to become owned by root and (in the worst case scenario) prevent the relevant software from being run by a normal user in future until the ownerships are fixed (which may be confusing for users) – Zanna Sep 12 at 7:20

  • thanks for explaining. I wonder if that behaviour is normal or expected. Some system settings areas prompt me for authorisation, but most do not. I would suggest editing your answer to note that you found you needed to use sudo for this purpose for some reason. It should also be recommended to use sudo -H if opening a GUI app with sudo – Zanna Sep 12 at 7:45
