MATE 1.6 supports systemd login
The MATE developers have released version 1.6 of their desktop environment. Originally derived from the source code of the last GNOME 2 release, the desktop environment offers a similar user interface. MATE 1.6 now works with the login manager of systemd, which has largely replaced ConsoleKit for user and session tracking in several distributions, and is also due to be used in the, as yet unnamed, Ubuntu 13.10.
This MATE upgrade comes with a warning
Unfortunately, due to migration to GSettings, you will lose your current panel layout. All other settings will be migrated if you have MateConf 1.4 installed.
If you are upgrading, any modifications you previously made to your panels (like the weather app or system monitor) will need to be replaced.
A second set of updates for MATE 1.6 was issued the following day to correct some bugs. This second update does not affect any of your desktop settings.
It will, however, restore the thumbnail view of video files that was lost in the original upgrade to 1.6.
This upgrade and subsequent update so far is only available through the PPA installation
. I have not seen this upgrade in Mint 13 yet.
