Unity desktop environment and Ubuntu Unity maintainer Rudra Saraswat Announcefor more information on continuing to develop UnityX. UnityX is a variant of the Unity7 desktop. It not only retains all the features of Unity 7, but also brings many additional features and supports newer GNU/Linux technologies.

UnityX (formerly known as UnityX 10) was originally designed as the next major version of the Unity desktop environment used by Ubuntu Unity. But for now, it appears that UnityX is being developed as a flavor of the upcoming Unity 7.7, which will offer even more customization options.

The appearance of UnityX is almost the same as Unity 7, but without using Compiz, users can choose Wayland as the window manager, replace or remove the top panel, and adjust the transparency of Unity Dash and Launcher.

UnityX also comes with a brand new Plotinus-based HUD, a HUD-like command panel for GTK3 applications that supports more applications than Unity7’s HUD, and can have multiple applications open at the same time.

Additionally, its System Settings application lets users change most UnityX desktop settings, and there’s a new way to configure UnityX and replace its components.

UnityX also supports Unity 7.7’s UWidgets plugin/widget system, as well as the new session indicator, Unity7’s appearance indicator, and the ability to open files directly from the global menu.

Both UnityX and Unity 7.7 will be released as part of the upcoming Ubuntu Unity 23.04 (Lunar Lobster) in late April 2023.
