GLF OS is the name of one of the craziest projects undertaken by the Gaming Linux Fr community.
This project consists in creating an operating system based on strict specifications, and fully developed by the community, for the community.
Important
Please note that secureboot must be disabled for GLF-OS to work for now.
No, we use a NixOS feature called Flocon that requires an internet connection to work.
Important
Installation time refers to the moment you click Install.
Installation time depends on your bandwidth. For example, with fibre-optic Internet and a recent machine, expect the installation to be 8 to 12 minutes long.
We provide all compiled binaries in the ISO. As a result, most packages do not need to be downloaded during installation.
However, please note that the boot loader (grub) is being downloaded during installation.
We have observed a minimum of 500MB downloaded during installation.
The servers distributing the package build cache (known as Cachix) can sometimes be slowed down during the day depending on current traffic.
Due to the nature of Nix, the calamares installer does not receive any information about the download progress, package compiling, etc.
Thus, the progress bar appears to be stuck at 46% while the installation is not.
You can click on the small magnifying glass at the bottom right of the installer to see what is happening.
Important
This display issue is not directly our responsibility; it is also present with NixOS.
We do not intend to fix it, as the low added value compared to the enormous amount of work involved is not worth the investment.
As of this stable release, there are no plans to add other desktop environments.
The software library we offer on GLF-OS is Easy Flatpak and it is provided in flatpak. It is installed right after the system installation and may take several tens of minutes to download depending on your connection.
More information about this here.
If you have already installed the stable version, you can switch to the testing version. To do so, you will find all the steps to follow here.
Important
We only recommend this procedure for people who want to test and contribute to GLF OS.
Updates are automatic on GLF OS. For more information on how they work, go here.
Important
Regular rebooting is recommended to ensure that all updates are applied.
GOverlay is available to configure MangoHud. You can enable or disable the overlay globally via the Global Enable option. More information here.
Note
After changing the Global Enable option, you must log out and log back in for the change to take effect.
The best thing to do is to let us know so that we can help you solve it or identify a bug that needs to be fixed. To do this, you can let us know on Discord or on Github, the links for which are available here.
