Last week at the SUSE offices in Nürnberg there was a meeting between developers of the KDE, GNOME, Unity, and Razor-qt desktop environments.
The focus of this recent open-source cross-desktop meeting was to collaborate around specifications that are inoperable between the Linux desktop environments.
Covered during the SUSE-hosted meeting were onn a specification for a new D-Bus application interface, a modification to the trash specification, a new file format to cache and index the contents of .desktop files, an update on the in-kernel D-Bus implementation, the account service future, a replacement for X11-based startup notifications, and numerous other topics.
