Although the number of Linux Desktops has fluctuated over time, the fact that several are available is an important Linux tradition. It follows the principle that programs should be modular and composable; you should be able to swap out your desktop for an alternative, easily and seamlessly.
This situation has endured, but for how much longer? Are competing DEs still viable, or have we reached the limit of our imagination?
How did we get here?
Many stages of evolution and mutation have shaped the Linux GUI
In the early days of graphical Unix, desktop environments weren’t even spoken of. The X Window System (1984) acted as a base on which other programs could create windows and related GUI elements. In 1987, twm (Tab Window Manager) was developed to layer now-familiar GUI elements like title bars and icons on top of X.
Later, in the 1990s, another layer of programs evolved to take advantage of the latest work in GUI development. These were called desktop environments, and were much more ambitious than window managers, adding vital user programs like a file manager and a dashboard, alongside features like virtual desktops. CDE (Common Desktop Environment) was the standard choice for commercial Unixes.
When Linux arrived in 1991, it took full advantage of this ecosystem. By supporting X, it could use existing window managers such as twm and fvwm. Even CDE was available, but since it was proprietary software (at the time), alternatives were sought. Xfce and Window Maker (both 1997) bridged the gap until two full-blown desktop environments were released almost simultaneously: KDE (1998) and GNOME (1999).
What’s the current status?
Plenty of desktop environments, but only two really matter
Launched in 2011, Cinnamon was forked from parts of GNOME to maintain its original desktop metaphor, which GNOME 3 had abandoned. Cinnamon is far from the only DE to take GNOME in a different direction; others, like Unity (2010), MATE (2011), and Budgie (2014), have also sought to address criticisms of GNOME’s change in direction.
But the pull of an established presence is strong and, although alternatives flourish, it’s fair to say that KDE and GNOME remain the two most popular options, at an estimated 40% and 25% market share respectively. Cinnamon follows with just 15% share, thanks to its status as the default DE of Linux Mint.
The newest kid on the block, COSMIC (2025), is a fascinating entry that has been fraught with issues, ranging from a lack of features to instability with NVIDIA graphics and other non-System76 hardware.
Deepin DE (DDE), which launched in 2019, has also struggled to find adoption outside its main distribution, with openSUSE abandoning it in 2025 over several concerns.
What challenges do the challengers face?
Can anyone seriously compete anymore?
Competing with KDE and GNOME has proven tough, so much so that the very concept of a desktop environment is under threat. The nuances of windowing systems, window managers, and desktop environments have long confused new users, and Linux’s adoption on the desktop has no doubt suffered as a result.
Threat: barrier to entry
The lack of a mainstream understanding of desktop environments means it’s difficult to innovate in this space. Many Linux beginners will install the default and stick with it, because there’s no clear drive to try an alternative.
Windows is Windows, macOS is macOS. Linux is a distro and a desktop environment. And a shell, and a window manager, and a windowing protocol, …
Threat: too niche
In such an environment, alternatives are typically niche: they target specific distros, hardware, or particular uses. For their target users, these DEs can be a revelation, but others will tend to overlook them.
While Linux users may understand the advantage of choice that the OS offers, many users just want an uncomplicated life, where things just work once you install them. This feeds into a self-fulfilling prophecy where KDE and GNOME are defaults, they are popular because they are recommended, and developers work on them because they are popular.
Threat: innovation often comes with bugs
System76’s COSMIC DE sounds like an exciting prospect, but switching to it could be a mistake—at least, right now.
With reports of problems ranging from applets and their icons disappearing to wonky context menus and apps not running at all, COSMIC isn’t the best choice for regular work. This is an inevitable byproduct of innovating in a complex space but, as a user, it still pays to be cautious.
Threat: the world isn’t ready for tiling windows
COSMIC Desktop bakes in tiling window management, and its marketing often makes a point of this feature. But many users are not fans of tiling, and will need some convincing to give up their stacked windows as the default.
Multiple desktop environments may be a choice too far
Desktop environments are alive, but barely. Unless we’re being generous, the only real success stories are KDE and GNOME—and many users simply stick with whatever they’re given.
If DEs were truly plug-and-play, without any associated difficulties, or if everyone were already using Linux, they might see more traction. But until either of those changes, I fear the great promise hasn’t been fulfilled—and certainly not when it comes to beginners.
