GNOME Shell and Ubuntu Unity both offer new looks

May 4, 2011 — by LinuxDevices Staff — from the LinuxDevices Archive — 4 views

With the release of GNOME 3.0 and Ubuntu 11.04, the face of the Linux desktop environment is changing. This eWEEK review finds there's a lot to like in both the GNOME Shell and Ubuntu Unity desktop environments, although both will take some getting used to.

With GNOME 3.0, the GNOME Foundation has diverged from the consistent look and feel that marked its namesake desktop environment for years. The new GNOME Shell interface represents a new desktop approach intended to make applications easier to access, limit workspace distractions, and make more use of modern desktop and notebook hardware.

The GNOME Foundation has overseen the development of the default graphical environments for the Linux- and Unix-based operating systems from Canonical, Red Hat, Novell, Canonical, Sun Microsystems, Oracle and others. However with Ubuntu 11.04, Canonical has broken ranks with GNOME by opting to not participate in GNOME Shell.

Instead, Canonical is offering a separate interface called "Unity." Unity is rooted in many of the same components and designed with many of the same goals as GNOME, albeit with different implementation details.

I've been testing both interfaces throughout their development and in their finished versions — I tested GNOME Shell in the beta release of Red Hat's Fedora 15, and Unity in the shipping version of Ubuntu 11.04. I've found each interface promising. Each does a solid job streamlining notification messages and staying out of the way of active applications.

With that said, both will require that users spend time adapting, and the enhanced hardware requirements of each will prove troublesome in certain scenarios. However, there's time for users and implementers to adjust to GNOME Shell and Unity.

The next Long Term Support version of Canonical's Ubuntu is set to ship a year from now, with an October release of the OS in between to address usability and hardware fallback issues. A 2D version of Unity is already available in the Ubuntu repositories. As for GNOME Shell, it's not clear when the new interface will make its way into the enterprise operating systems from Red Hat, Novell, or Oracle.


The new GNOME environment starts users off with a blank desktop that seems to serve only as a sort of wallpaper for one's computer — there are icons to interact with, and if you store files in the "Desktop" folder, they don't show up on the desktop.

Across the top of the screen, there's a panel with date and time, volume control, network status, power manager, and a small settings and login button. Moving the cursor to the upper left side of the screen brings the environment to life, pulling up a desktop overlay, with a panel containing application links to the left and a virtual desktops panel to the right.

Also on the right is a search box that I could use to locate applications on my test system. I was also able to browse through a grid of installed applications by clicking an "Applications" button toward the top of the overlay.

Moving the cursor to the bottom right of the screen pulls up a second panel, where applications that typically stay running in the system tray live. For instance, once opened, Fedora's chat application lives in this bottom panel, and when new instant messages come in, a notification window pops up from the panel with the message text.

On my test system, I could respond to instant messages from this same notification window. After opening an application, I noticed that application windows lack maximize or minimize buttons, though I could access these commands by right-clicking on the title portion of the window.

For applications such as the instant messenger client, clicking the "close" button serves the same purpose as minimizing, and the bottom panel provides a place to reopen the minimized application.

The removal of minimize/maximize has been one of the leading complaints among GNOME users over the new interface.

Ubuntu Unity

Ubuntu's new Unity interface departs a bit less dramatically from the GNOME 2.x look and feel. For instance, files saved to the desktop still show up there, and the typical assortment of panels, menus, and window buttons remain, although they've been shifted around somewhat.

Whereas the previous Ubuntu interface sported panels at the top and bottom of the display, Unity ships with an application launcher panel at the left of the display and a combination application menu and status indicator panel across the top of display.

By default, Ubuntu application menus follow the Apple OS X global menu convention — the menu of the active, foreground application appears across the top of the display. I'm not a fan of this menu configuration, so I was pleased to find that it was possible to revert to the previous menu behavior.

As with GNOME Shell, Unity taps search for locating and launching applications installed on one's system, although Unity also suggests applications available for installation from Ubuntu's software repositories.
