MATE

MATE (pronounced to rhyme with latte, not late) is a fork of the GNOME 2 desktop environment by the MATE team, which is available through Portage. According to their manifesto, they aim to keep a traditional desktop look and feel, maintain an open development model, have an open relationship with GNU/Linux distributions, and serve as a good alternative for lower-end hardware.

USE flags
First enable or disable desired USE flags for.

Emerge
To install the MATE desktop environment meta package run the following command:

As of April 2015, MATE 1.8 was stable on and.

Additional packages
To install Caja file manager extensions run the following command:

Caja extensions include the following:


 * - Open terminals in arbitrary local paths
 * - Integrate email clients and Pidgin into the Caja file manager
 * - Mass resize or rotate images
 * - Quickly share a folder from the Caja file manager

Usage
Either a display manager (SLiM, GDM, LightDM, etc.) or the startx command can be used to start MATE during system the system boot process.

Display manager (DM)
To make the display manager work specify a MATE session (mate-session) in the configuration of the display manager; some perform this action interactively, others will need to have a configuration file modified. The default session can also often be changed by setting  in :

Manual start
To start MATE manually create a file in a user's home directory. Make its contents as follows:

Note that you might need to put ck-launch-session and/or dbus-launch between exec mate-session for ConsoleKit and/or DBUS communication to work, for example:

Compositing
Compositing is not enabled by default. To enable compositing run and click the tick box alongside Enable software compositing window manager in the  tab.

Window centering
Window centering is not enabled by default. To enable window centering run and click the tick box alongside Center new windows in the  tab.

Window snapping
Window snapping is not enabled by default. To enable window snapping run and click on the tick box alongside Enable side by side tiling in the  tab.

Change applications menu icon
The applications menu icon is set to by default. To use a different icon, copy your icon to a folder such as and execute the following:

where icon is the name of your icon without the file extension. Restart MATE panel.

Does MATE rely on a specific service manager or init system?
No, MATE has been tested to work with both OpenRC and systemd and might work on other service managers and init systems too (untested, but no known reason for it to break); systemd support was added in release 1.6.

Can MATE be installed side-by-side GNOME packages or do they block?
As the MATE packages use their own categories, it is possible to have MATE and GNOME 3 installed at the same time which allows you to test either; taking it even a step further, if you change MATE to not have a top panel (as it gets hidden under the GNOME 3 shell) you can even start mate-session within GNOME 3 and run MATE and GNOME 3 at the same time.

How do I enable the panel shadow?
Due to a race condition, the panel shadow does not appear after logging in to the MATE desktop, even with compositing enabled. You must first copy to. Then set to, and add a delay:

You may need to adjust the delay as needed. Finally, restart Marco with the following command:

GLib-GObject-ERROR: object GsmAutostartApp 0x73ca40 finalized while still in-construction
When you get this error (see ~/.materc-errors), it is usually preceded by a warning, fixing the warning could fix the problem; for example, when I get to see:

In this case, you can resolve this by moving away the desktop file or fixing it up by adding the Name key. If you want a clean start, you can move those files out of the way by backing them up:
