From MATE homepage:
- The MATE Desktop Environment is the continuation of GNOME 2. It provides an intuitive and attractive desktop environment using traditional metaphors for Linux and other Unix-like operating systems. MATE is under active development to add support for new technologies while preserving a traditional desktop experience.

- The group contains the core desktop environment required for the standard MATE experience.
- The group contains additional utilities and applications that integrate well with the MATE desktop. Installing just the group will not pull in the whole group via dependencies. If you want to install all MATE packages then you will need to explicitly install both groups.
The base desktop consists of, and .
MATE is largely composed of GNOME 2 applications and utilities, forked and renamed to avoid conflicting with their GNOME 3 counterparts. Below is a list of common GNOME applications which have been renamed in MATE.
|image viewer||Eye of GNOME||Eye of MATE ()|
|archive manager||File Roller|
Other applications and core components prefixed with GNOME (such as GNOME Terminal, GNOME Panel, GNOME Menus, etc.) have had the prefix changed to MATE so they become MATE Panel, MATE Menus etc.
Additional MATE packages
There are a number of other unofficial MATE applications that are contributed to and maintained by the MATE community and therefore not included in theor groups.
- Dock Applet — Application dock for the MATE panel.
- Online Radio Applet — A MATE panel applet to let you play your favourite online radio station with a single click.
- MATE Menu — Advanced menu for MATE Panel, a fork of MintMenu.
- MATE Tweak — Tweak tool for MATE, a fork of mintDesktop.
- BriskMenu — Modern, efficient menu for the MATE Desktop Environment from SolusOS distribution.
Additional packages need to be installed to take advantage of some of Caja's advanced features - see File manager functionality.
Consider the following community efforts, cf. forum:
Choose MATE from the menu in a display manager of choice.
Alternatively, to start MATE with startx, append
exec mate-session to your
~/.xinitrc file. See xinitrc for details, such as preserving the logind session.
MATE can be configured with its Control Center application (mate-control-center) provided by thepackage. To manage some hardware, you may need to install additional tools.
- ALSA and PulseAudio backends are supported by the package.
- For Bluetooth device support, install the package. See Blueman.
- For configuring the network, install the NetworkManager. package. See
- UPower backend is supported by the package.
- For configuring the printers, install the package.
MATE is well suited for use by individuals with sight or mobility impairment. Install , (Screen reader for individuals who are blind or visually impaired) and (On-screen keyboard useful for mobility impaired users)
Before starting MATE for the first time, enter the following command as the user who needs accessibility features:
$ gsettings set org.mate.interface accessibility true
Once you start MATE, you can configure the accessibility applications via System > Preferences > Assistive Technologies, although if you need Orca, you will need to run it from the
Alt-F2 run window in order to start getting speech.
- Battery discharge
To disable the notification on battery discharge, run:
$ gsettings set org.mate.power-manager.notify-discharging false
Tips and tricks
Compositing is enabled by default. To otherwise enable or disable it navigate to run System > Preferences > Look and Feel > Windows > General and click the tick box alongside Enable software compositing window manager. Alternatively, e.g. to enable it, you can run the following from the terminal:
$ gsettings set org.mate.Marco.general compositing-manager true
Enabling/disabling new window centering
By default, new windows are placed in the center. To otherwise enable or disable centering new windows on creation navigate to run System > Preferences > Windows > Placement and click the tick box alongside Center new windows. Alternatively, e.g. to enable it, you can run the following from the terminal:
$ gsettings set org.mate.Marco.general center-new-windows true
Enabling/disabling window snapping
Window snapping is enabled by default, to otherwise enable or disable it navigate to run System > Preferences > Windows > Placement and click the tick box alongside Enable window tiling. Alternatively, e.g. to enable it, you can run the following from the terminal:
$ gsettings set org.mate.Marco.general allow-tiling true
Undecorating maximized windows
Hiding the decorations of maximized windows is possible with theAUR tool: After installing it, navigate to System > Preferences > Look and Feel > MATE Tweak > Windows and enable Undecorate maximized windows in the Window Behaviour section.
Show or hide desktop icons
By default, MATE shows multiple icons on the desktop: the content of your desktop directory, computer, home and network directories, the trash and mounted drives. You can show or hide them individually or all at once using
Hide all desktop icons
$ gsettings set org.mate.background show-desktop-icons false
Doing so may cause some graphics artifacts on secondary monitors.
Hide individual icons
Hide computer icon:
$ gsettings set org.mate.caja.desktop computer-icon-visible false
Hide user directory icon:
$ gsettings set org.mate.caja.desktop home-icon-visible false
Hide network icon:
$ gsettings set org.mate.caja.desktop network-icon-visible false
Hide trash icon:
$ gsettings set org.mate.caja.desktop trash-icon-visible false
Hide mounted volumes:
$ gsettings set org.mate.caja.desktop volumes-visible false
true for the icons to reappear.
Use a different window manager
The marco window manager can be replaced with another window manager via either of the following methods:
- Using gsettings (recommended)
Execute the following to specify a different window manager for MATE:
$ gsettings set org.mate.session.required-components windowmanager wm-name
- Using MATE session autostart
You can autostart a window manager of your choice using mate-session-properties. This means that the autostarted window manager will replace the default window manager at login. Navigate to System -> Preferences -> Startup Applications. In the dialog click Add. The command should take the syntax
Prevent Caja from managing the desktop
To prevent Caja from managing the desktop, execute the following:
$ gsettings set org.mate.background show-desktop-icons false $ killall caja # Caja will be restarted by session manager
You can change the button order using the graphical dconf-editor or the gsettings command line tool:
$ gsettings set org.mate.Marco.general button-layout 'close,maximize,minimize:'
and put menu, close, minimize and maximize in your desired order, separated by commas. The colon is used to specify on which side of the titlebar the window buttons will appear and must be used for the changes to apply.
Auto open file manager after drive mount
By default, MATE automatically opens a new file manager window when a drive is mounted. To disable this:
$ gsettings set org.mate.media-handling automount-open false
And to disable automounting:
$ gsettings set org.mate.media-handling automount false
MATE uses XScreenSaver screensavers with .to lock your session. By default there are a limited number of screensavers available. To make more screensavers available, install the AUR package. This will allow you to use
Spatial view in Caja
To ensure that each new folder opens in a new window (known as spatial view), open Caja's preferences dialog, click on the behaviour tab and tick the 'Open each folder in its own window' option. Alternatively, execute the following command which achieves the same effect:
$ gsettings set org.mate.caja.preferences always-use-browser false
Change font DPI setting
You can alter the DPI (dots per inch) of the fonts in MATE by right-clicking on the desktop and choosing Change desktop background > Fonts > Details > Resolution.
By default, the applications menu icon is set to
start-here. To use a different icon, copy your icon to a folder such as
/usr/local/share/pixmaps and execute the following:
$ gsettings set org.mate.panel.menubar icon-name icon
where icon is the name of your icon. Do not include the file extension in the icon name. Finally, restart MATE Panel.
Panel speed settings
- Hide/Unhide delay
To adjust the amount of time it takes for the panel to disappear or reappear when autohide is enabled, execute the following:
$ dconf write /org/mate/panel/toplevels/panel/(un)hide-delay time
where panel is either top or bottom and time is a value in miliseconds, e.g. 300.
- Animation speed
To set the speed at which panel animations occur, execute the following:
$ dconf write /org/mate/panel/toplevels/panel/animation-speed value
where panel is either top or bottom and value is either
Set the terminal for caja-open-terminal
caja-open-terminal extension uses GSettings to determine which terminal to use - mate-terminal is the default. To change the terminal that will be used, run the following command
$ gsettings set org.mate.applications-terminal exec my-terminal
where my-terminal is the name of the terminal executable to be launched, for example: xterm.
Some software may have issues rendering graphics when working on an environment using the nvidia proprietary drivers and a compositing window manager.
To easily toggle the compositing feature, save the following script somewhere within the Home directory, e.g.
#!/bin/bash if [ "$(gsettings get org.mate.Marco.general compositing-manager)" = "true" ] then gsettings set org.mate.Marco.general compositing-manager false else gsettings set org.mate.Marco.general compositing-manager true fi
and then create a custom keyboard shortcut that executes the file, e.g.
Vertical sync for compositing
Mate's window manager, marco, supports tear-free software compositing via DRI3/Xpresent. 
If your graphics driver does not support DRI3 (e.g. the Nvidia Proprietary driver), marco does not support vertical synchronization via OpenGL, which may cause video tearing with enabled compositing.  In this case, consider a different composite manager with OpenGL support such as Compton.
Consistent cursor theme
Use of gradient backgrounds with LightDM
If you wish to use the default MATE (1.8) Stripes background as the LightDM background as well so as to make for seamless transition from LightDM to MATE, you will find that it is runtime-constructed from a grayscale PNG upon which MATE layers a vertical blue-to-green gradient, something which LightDM does not currently support. If insistent, you can work around this by temporarily setting
false, either through the
dconf-editor tool available from the
System Tools menu or by running
$ gsettings set org.mate.background show-desktop-icons false
from the Alt-F2
Run Application dialog, then running
killall mate-panel from said dialog and hitting
Print Screen before the panel reappears. You are then presented with a
Save As dialog for exactly that fully rendered, screen-sized PNG that you need for LightDM. Run
$ gsettings set org.mate.background show-desktop-icons true
to have your desktop icons reappear, if desired.
Enabling panel shadow
Due to a race condition, the panel shadow does not appear after logging in to the MATE desktop, even with compositing enabled. 
/usr/share/applications/marco.desktop and add a delay:
X-MATE-Autostart-Phase=Applications X-MATE-Autostart-Delay=2 X-MATE-Provides=windowmanager X-MATE-Autostart-Notify=true
X-MATE-Autostart-Phasemust be set to
If this has no effect, increase the delay duration.
Disabling scroll in taskbar
A feature of the MATE panel window list is that windows can be scrolled through using the mouse or touchpad. This feature may be troublesome for some as there is potential for accidental, unintended scrolling through windows.
Whilst there is no way of disabling this feature through MATE's settings, this feature can be disabled by patching Arch Build System; in this case, rebuild libwnck3 with the following patch. For more information on rebuilding packages with patches applied, see Patching in ABS#Applying patches.using the
Logout/shutdown delayed by at-spi-registryd
When logging out or shutting down, you may find that you are presented with an A program is still running: at-spi-registryd.desktop popup. As a workaround, you can prevent at-spi-registryd from starting - see GTK+#Suppress warning about accessibility bus - though this may have an effect on some accessibility features.
Caja's text file preview
Since the migration to GTK+3 this feature is not working.
