How to install Lubuntu 22.04 Trinity desktop environment?

How can I do that? I want to use Trinity instead of LXQT.

We don’t support the Trinity desktop; I don’t see it uploaded to either Debian or Ubuntu.

I’ll provide a link to Preliminary Stable Builds - Trinity Desktop Project Wiki which does say it supports jammy or 22.04.

If you need support; you’ll still be using Ubuntu 22.04 LTS, but won’t be running Lubuntu and its LXQt desktop.

You’re probably better off using a distro that already comes with the desktop or has a focus for it.

Q4OS comes to mind but that’s pretty much a Debian distro and not really an Ubuntu experience.

I agree with the earlier comments. However, if you insist, instructions for various distributions are here: Trinity Desktop Project Wiki.

I did not test it on Lubuntu, but I am pretty sure the instructions for Ubuntu will work.

Curious as always, I will install it on Arch Linux, and not on Lubuntu. I guess it will take me less than half a hour to install it from scratch, with only a handful of terminal commands after installing a bare minimum Arch system (without the need for installing LXQt or another desktop environment). If you like I can share the details with you.

If you really want the Ubuntu experience, but without all the extras that the default Ubuntu desktop bloats, just install a server version of Ubuntu, and then follow the instructions.

In fact, it is quite possible to install the Trinity desktop alongside an existing LXQt based Lubuntu installation. (You don’t need to start with fresh Ubuntu.)

I’ve followed the instructions for the latest version of Trinity on a Ubuntu 24.10 system.

There is only one small tricky thing in the instructions: you just need to know that the distribution specific name of Ubuntu 24.10 is (“oracular”).

The rest of the installation is easy-peasy. I’ve decided to go full monty, and installed the comprehensive version (not the base variant).

Somewhere during the installation I’ve opted for the already existing sddm window manager (and not the proposed Trinity variant).

After installing, the next time you see the log in-screen - which is part of the sddm greeter and not part of the actual desktop - just select at the top “TDE” as session instead of “Lubuntu”.

You have now a fully functional Trinity and LXQt desktop running on the Lubuntu variant of the Ubuntu OS. Next time you log in you can switch back to LXQt (if desired).

Trinity (comprehensive) seems to be a very complete system. Everything works nice. It has a bit of old-fashioned look (which you can change in the settings a bit).

I know of some people who would be very pleased to have the Trinity desktop and not modern KDE Plasma, or LXQt, xfce, or anything else in fact.

If I am honest I need to tell that it is not my favorite desktop and never will be (I prefer LXQt). It is very workable, and it needs some more attention than it gets today. Certainly the maintainers deserve a lot of respect.

As That_Random_Guy mentioned, Q4OS deliver the Trinity desktop as well, using a Debian derived system (as I read it on their website).

I have not tested Q4OS but I am a bit hesitant with derived OS-es in general.

Security wise.

To be fair, I don’t know any of the Q4OS team members, nor about any problem. But I also don’t know their speed on following the base Debian system when there are regular updates and specially when security problems are fixed in Debian. The world can be a dangerous place if derived OS-es are not patched correctly or quick enough.

So I just don’t know what their track record is. However I do know that on the Q4OS website (Q4OS - desktop operating system) it is stated that the project seeks investors and developers. Better save than sorry: if someone wants “the” Debian experience with the Trinity desktop, better use Debian proper and install Trinity yourself.

BTW. I have the same fears about several other derived OS-es (e.g. SparkyLinux or Garuda to name just two).

I want my desktop (mostly LXQt) to run on an OS that is scrutinised sufficiently.

Ubuntu is derived from Debian, and is the positive exception

I have no fear of using Ubuntu, nor its derived Lubuntu, which core is essentially at any time the same as Ubuntu :-

I have tried Q4OS on more than one occasion and the integration of the desktop with the system is perfect. As my colleagues have said, I think it is the best option.
