LCARS Desktop Environment, official project name lcarsde, is a desktop environment that mimics the LCARS interface. LCARS is an acronym for Library Computer Access/Retrieval System, a computer operating system which features in the Star Trek: The Next Generation series.
The desktop environment consists of a window manager that is based on Xlib as well as a set of tool applications, which are a menu of active open applications, the status bar, a program selection and an application for logout, shutdown, etc. lcarsde does not provide its own display manager.
lcarsde consists of five parts:
- LCARS Window Manager – a stacking window manager and displays one window at a time per screen. Windows always open on the primary monitor and can be moved to other monitors with keyboard shortcuts. lcarswm has two kinds of monitors, one primary monitor (which maps to the X primary monitor) and “other” monitors. Only the primary screen has the upper (currently empty) information area and the side bar that shows the app menu. The information area and the app menu are only visible in the normal screen mode. There are three screen modes
- Application Menu – lists all open windows and allows to focus or close them.
- Status Bar – shows some system information like CPU usage and connectivity status and offers some buttons to perform actions like open a program or adjusting the sound.
- Application Selection – lists all installed programs (with a desktop file) in their categories and allows to run them by clicking on the programs button. In the default status bar configuration, this application is available via the button that is labeled “programs”.
- Logout Application – offers buttons for logout, shutdown, restart, … . In the default status bar configuration, this application is available via the button that is labeled “close”.
This is free and open source software.

Star Trek: TNG is my favorite in the series.
I still prefer Star Trek TOS but that wouldn’t make for a great desktop environment 🙂
TNG had a few really nauseating characters.
Who are these characters that you label nauseating?
Wesley Crusher, Q, and Lwaxana Troi.
I agree regarding WC but I didn’t mind LT. Besides, neither were central characters.
I never said they were central characters. But WC appeared regularly in Seasons 1-4 and as a guest for seasons 5 & 7. Wikipedia considers the character as one of the main cast, and the other two are recurring characters.
I really like Majel’s character in TOS.
I know, I just meant that since they weren’t central characters [LT might just barely fit that criteria], I didn’t see it as being a major issue.
I enjoyed the episodes with Q.
Perhaps just watch the episodes without them or at least episodes with just one of them.
Way offtopic I know, but Alex, what’s your fav TOS episode?
There are so many great episodes for both TOS and TNG. For TOS, my personal fav is “The City on the Edge of Forever”.
Not that keen on the fact you have to install each component separately, but it all compiles fine on Arch.
While the intention of the project is commendable, the desktop gets in the way of my workflow. Back to Plasma.
Yes, I’d prefer a single package but it installs on Manjaro with no issue. I’ve yet to try it under Ubuntu. The project provides packages for Ubuntu 22.04, but I’m mostly using 24.04 these days.
