Add custom App entries to System Settings
To add a custom app to System Settings (Gnome Control Center), find its desktop entry file - /usr/share/applications/{appname}.desktop
and edit it to ensure that the following entries are present:
Categories=Settings;X-GNOME-Settings-Panel;xxxxx;
X-GNOME-Settings-Panel={appname}
Replace {appname}
with the name of the App you're adding to System Settings.
xxxxx
decides the Section where your app is displayed. Replace xxxxx
with one of these possible options:
X-GNOME-PersonalSettings - Personal Section
HardwareSettings - Hardware Section (Note that prefix X-GNOME is not used)
X-GNOME-SystemSettings - System Section
After the modifications run this command:
sudo update-desktop-database
This was tried and tested on Ubuntu 12.04 LTS12.04 with gnome-control-center version 3.4.2-0ubuntu0.12
Things to Note:
- System Settings don't recognise desktop files in
~/.local/share/applications
and as a result,it's not possible to add Apps to System Settings for one user alone. - As noted by Manish Sinha in this Answer, Ubuntu uses a
gnome-control-center
with Ubuntu specific patches which enables the addition of custom entries. As a result,this method is Ubuntu specific and won't work on vanillagnome-control-center
used by other distros.

Actually, having
X-GNOME-Settings-Panel;X-GNOME-SystemSettings;
inCategories
and addingX-GNOME-Settings-Panel=sample
is sufficient.– nem75Aug 24, 2012 at 7:52 -
@nem75 that didn't work for me on Ubuntu 12.04, but the settings from lancer did– realgtOct 17, 2012 at 12:44

the settings from lancer allowed me to add gnome-tweak-tool to my System Settings by modifying /usr/share/applications/gnome-tweak-tool.desktop– realgtOct 17, 2012 at 13:19

If you want the launcher show up under Personal section, use X-GNOME-PersonalSettings instead of X-GNOME-SystemSettings. For Hardware section, use HardwareSettings (note that prefix X-GNOME is not used and doesn't even work. Some inconsistency here, don't you think?) Jan 22, 2013 at 15:00

Are there any other possible categories besides Personal or System Settings? And what theme are you using? Nov 27, 2014 at 0:35

Right now adding custom items to System Settings is not support upstream from GNOME
Ubuntu patches System Settings gnome-control-center
so that it can include it's own ubuntu specific entries in it.
Long story short, you need to install libgnome-control-center-dev
and create a wrapper around your application which is built against gnome-control-center package using libgnome-control-center-dev
for pkg-config
Right now there is no GUI method to add it. You need to do it programmatically using C and it would work only on Ubuntu.
The reasoning for not allowing third party entries (called panels) is detailed by David Zeuthen

Yes. I also think we tried that with GNOME 2 and failed. I mean, look
at GNOME 2's control center - on all distros, it's a royal mess of
random crap from either GNOME, the distro or 3rd party app written by
a kid in a basement. With GNOME 3.2, we will have a simpler control
center (since the extension mechanism is going away) but it will be
_awesome_.
Update of answer from @lancer for Ubuntu 14.04 lts:
It may come from the fork of gnome-system-settings from the ubuntu team as I could read on some blog post somewhere ( can't recall where .. :/ )
anyway, the following 2 lines shows the differences, & a more thorough example follows
X-Unity-Settings-Panel={appname}
Categories=GNOME;GTK;Settings;X-Unity-Settings-Panel;xxxx;
ex:
[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=TefApp
Name[C]=TefApp
Exec=/home/stephaneag/Documents/ubuntu_CustomSystemSettingsEntryApp/dummyScript.sh
Comment[C]=dumb dummy app
StartupNotify=true
Icon=utilities-terminal
Terminal=false
NoDisplay=false
# the following is necessary for the .desktop to be accepted in System Settings
# for our stuff to appear in "System" section:
#Categories=GNOME;GTK;Settings;X-Unity-Settings-Panel;X-GNOME-SystemSettings;
# for our stuff to appear in "Hardware" section:
#Categories=GNOME;GTK;Settings;X-Unity-Settings-Panel;HardwareSettings;
# for our stuff to appear in the "Personal" section:
Categories=GNOME;GTK;Settings;X-Unity-Settings-Panel;X-GNOME-PersonalSettings;
OnlyShowIn=Unity;
Update for 14.04 with specific details on replacing default Users program with users-admin so groups can be changed.
install gnome system tools with users-admin
sudo apt-get install gnome-system-tools
- Edit users-admin desktop so it shows up in Unity Control Center - see entry below
Move old user desktop so it does not show up in Unity Control Center
cd /usr/share/applications/ mv unity-user-accounts-panel.desktop unity-user-accounts-panel.desktop.ORIG
Update database
sudo update-desktop-database
This was tested on Ubuntu 14.04 LTS. Do not know how an system update will effect the updated files. Will have to inspect on next upgrade.
/usr/share/applications/users.desktop:
[Desktop Entry]
Version=1.0
Name=Users and Groups
Comment=Add or remove users and groups
Exec=users-admin
Icon=config-users
Terminal=false
Type=Application
StartupNotify=true
Categories=GNOME;GTK;Settings;X-Unity-Settings-Panel;X-GNOME-SystemSettings;
OnlyShowIn=Unity;
X-Unity-Settings-Panel=users
