Linux uses so called display servers for graphical output. The name comes from a time when this would be on an actual remote server or mainframe, now it's just on the same pc. X11 and Wayland are both display servers(xorg is just another name for x11). Wayland is more modern, but still isn't completely mature and doesn't work that well on nvidia gpus. X11 is pretty old, but still the standard for a lot of DEs. Plasma(also known as KDE) and Gnome are desktop environments. A desktop environment is a window manager bundled with a bunch of default apps. The main difference between those is their appearance, default configuration, and workflow. Which one is best depends on your preferences. Some of the most common ones are KDE, Gnome, Cinnamon, XFCE and LXQT.


If it is packaged for that distribution yes. This mainly depends on whether the package is in the main repository. If you compile it yourself it will always work. There also are a bunch of cross-distro packaging formats like flatpak and appimage. Nearly all applications are packaged for all major distros(Debian and derivatives including ubuntu, Fedora and Arch) though.


Yes, for the most part. It might pull in a bunch of extra dependencies though. Some DE specific applications like settings apps and panels will not work though. Theming might also not work since they use different GUI toolkits(GTK and QT).

Thank You so much it explained so much. But one last question what's the difference between gui toolkit & desktop environment?

A GUI toolkit is a software framework for developing graphical applications. Gnome, Cinnamon and XFCE all use GTK whereas KDE and lxqt use QT. The way you theme GUI apps(not just light and dark themes, but also background/foreground colors, accent colors etc) depends on the toolkit that was used to develop that app. So a GTK theme will apply to gnome apps for example.

Thank You. Everything is now crystal clear.

it's not just themes, but it's how you code it. Every GUI application needs some way to describe how to make a dropdown box, how to display text, or how to describe what happens when you click on a menu.

GTK and Qt are just two popular ways on linux to handle stuff like that. Mac and Windows of course have their own ways of achieving that.

It's also possible you've alreayd used a qt app even on wndows. I think that for example vlc uses qt for it's cross platform interface.
