I recently found out about a Linux Distro named Q4OS and I wanted to test out their claim that it only requires 256 MB of ram when using the trinity desktop environment. However, when I used the live cd in virt-manager with 256 MB or ram, it just kernel panicked at boot. So I then tried it with 512 MB of ram. In addition to some issues that are not present when you are using at least 1 GB of ram, such as “sudo apt update” causing the entire VM to become unresponsive, I noticed that it seemed to actually use anywhere between 290 MB to 370 MB of ram when the only thing running was the process viewer (which is htop).

Obviously, this is still very low for a modern Linux distro but I was wondering how accurate VMs are for testing ram usage.

And, yes I know that it would be pretty much useless on a PC that only had 256 MB of ram even if it did work. I’m actually checking the ram usage because there is a possibility that I may be using a very old computer of mine that only has 1 GB of ram at some point in the future. So I’m just testing it and eventually other distros out to to see which one I’m going to end up using (assuming I do actually end up even using that computer).

Edit: I just tried the 32-bit version in virt-manager and htop stated it was only using 232 MB of ram, which means that their claim was right and that I might have been using the wrong version.

Edit 2: I just tried installing the 64-bit version in virt-manager and htop stated that it was using about 350 MB of ram, so I don’t know if installing it actually made a difference.

    If you only have 1 GB of RAM, you definitely need to use a 32 bit distro. Regardless of the WM or DE, 64 bit software is going to chew through that 1 GB fast.

    I have been playing around with the Q4OS Trinity 32 bit and I had forgotten how much lighter 32 bit software is memory-wise. I have a full DE ( Trinity ), Firefox with a couple tabs, Thunar, LibreOffice Calc, GIMP, and Scribus all open and I am still only using 935 MB. Awesome.

    It is certainly the lightest systemd based distro I have used.

    There is definitely some software missing from the repos. I could not find dotnet or Visual Studio Code which I am sure are in 64 bit Debian. But Nala, Neovim, GCC, Clang, Rust, Go, and friends are all still there. Libmobiledevice connects to my iPhone just fine.

    It even has Podman and Distrobox although none of the 64 bit images work of course.

    Lxqt is in the Q4OS 32 bit distros. You could try that if you want but Trinity seems fine.

      Quick follow-up for anybody curious. I did install Lxqt on 32 bit Q4OS. It uses about 60 MB more than Trinity.

      As a desktop, I think I like Trinity better ( Trinity is essentially KDE 3 ). Some of the lxqt companion utilities were nicer though ( I liked lxqt-terminal more than Trinity Konsole for example ). Of course, you can install and use the tools with either desktop.
