The GNOME Display Manager is a system service that is responsible for providing graphical log-ins and managing local and remote displays.

To build and install GDM from source, just execute the following commands:

$ meson _build
$ ninja -C _build
$ sudo ninja -C _build install

You can browse the code, issues and more at GDM's GitLab repository.

If you find a bug in GDM, please file an issue on the issue tracker. Please try to add reproducible steps and the relevant version of GDM.

If you want to contribute functionality or bug fixes, please open a Merge Request (MR). For more info on how to do this, see GitLab's help pages on MR's. Please also follow the GDM coding style, which is documented in HACKING.

If GDM is not translated in your language or you believe that the current translation has errors, you can join one of the various translation teams in GNOME. Translators do not commit directly to Git, but are advised to use our separate translation infrastructure instead. More info can be found at the translation project wiki page.
