Several Linux desktop behaviors that Jack Wallen misses were never universal features, and some remain available only in particular desktop or window-manager setups. Their common thread is user control: changing how windows look and move, recovering a session, and making the desktop feel playful. Here are the seven he recalls—and what each one actually does.
Why these features were never universal
Jack Wallen’s list is a personal selection of behaviors he valued, not a checklist of features removed from every Linux desktop. Desktop behavior depends on the application, window manager, compositor, display server, configuration, and version in use. A remembered feature may still exist in a particular setup, but that is different from being a standard capability across Linux.

That distinction matters most when moving between X11 and Wayland. They use different display and compositing architectures, and compatibility for older X11 applications does not automatically preserve every older desktop component or effect.
1. Transparency across the desktop
Wallen recalls using transparency not just for windows, but also for menus, borders, and applets. The appeal was visual customization: a desktop could be made to look layered and distinctive rather than like a collection of opaque panels.

That is a preference, not evidence of a usability or performance improvement. Wallen also recalls older hardware handling the effects efficiently, but that recollection was not independently established. Whether transparency is available or practical depends on the desktop’s compositor and configuration.
2. Ctrl+Alt+Backspace as an emergency exit
In the documented Xorg setup, Ctrl+Alt+Backspace terminates the X server. It is a blunt way to end a stuck graphical session—not a shortcut that closes one unresponsive application while preserving the rest of the desktop.
The key combination may be disabled, and X.Org’s release notes describe a keymap choice intended to prevent accidental termination. Its availability and effect therefore depend on the session and configuration. When an application is the problem, an application-level quit or recovery option is less destructive; this combination ends the graphical session.

3. Middle-click paste
Middle-click paste is associated with X’s PRIMARY selection: selected text becomes the current selection, and a middle-click traditionally inserts it at the pointer. It is separate from CLIPBOARD, which is used by explicit copy and paste actions such as Ctrl+C and Ctrl+V. The conventions are documented in the GNOME discussion of PRIMARY selection and Wayland.
This is not a Linux invention, nor does every application or distribution support it in the same way. The archived GNOME Wayland discussion records concerns about sharing selected text implicitly, including security and discoverability. As a result, behavior can differ between applications and session types; middle-click should not be assumed to paste the same content as the explicit clipboard.

4. Expressive Enlightenment themes
Wallen remembers Enlightenment themes that changed window-decoration shapes as well as colors. That kind of theming made the desktop’s visual identity more than a choice of palette: it could change the silhouette of the windows themselves.

His examples describe what he enjoyed, not a current catalog of themes or a maintained recommendation. Theme availability and compatibility need to be checked for the particular Enlightenment version in use.
5. Vertical title bars
A vertical title bar can shift window controls and identifying text to a side, potentially reclaiming horizontal space. Wallen recalls configurable vertical bars as a useful way to make more room on screen.
This is a window-manager or desktop capability, not a standard Linux setting. A currently supported desktop and version with this option was not established, so check the configuration documentation for the specific environment rather than expecting a system-wide toggle.
6. Shaded windows
Window shading rolls a window up into its title bar after a title-bar action, leaving the bar visible while the window’s contents are hidden. Wallen recalls this being available in some environments and often not enabled by default.
Availability and the action used to trigger it vary by window manager and configuration. There is no established cross-desktop compatibility list here, so verify the option for the exact environment and version before relying on it.

7. Compiz’s playful effects
Wallen remembers effects such as the workspace cube, wobbly windows, and animated transitions. For him, these made desktop navigation entertaining as well as functional.
His shorthand that Wayland made Compiz unnecessary points toward a real architectural shift, but it should not be read as a universal compatibility rule. Wayland integrates display-server, window-management, and compositing responsibilities differently from the traditional X11 arrangement. Xwayland allows many existing X11 applications to run in a Wayland session; it does not make an X11 window manager responsible for native Wayland windows. The Wayland FAQ and the Wayland documentation book explain the architecture and X11 application support.
Consequently, an older X11 application running through Xwayland does not guarantee that an old desktop-wide effect will manage or animate native Wayland windows. Whether an effect is available depends on the compositor and desktop implementation.
Quick Recap
What to check before trying to bring one back
- Identify the session: determine whether the desktop is running an X11 or Wayland session; behavior tied to one architecture may not carry over to the other.
- Check the component and version: title-bar orientation, shading, themes, and visual effects belong to specific desktop or window-manager implementations, not Linux as a whole.
- Look for an opt-in setting: some behaviors may be configurable rather than enabled by default. Do not assume that a remembered shortcut or effect is active.
- Distinguish compatibility from native support: Xwayland supports many X11 clients, but it does not provide a blanket path for old X11 window managers or effects to control native Wayland windows.
- Choose recovery actions carefully: terminating the X server ends the graphical session; it is not equivalent to closing a single stuck application.
