GNOME (/(ɡ)noʊm/) is a desktop environment that aims to be simple and easy to use. It is designed by The GNOME Project and is composed entirely of free and open-source software. GNOME is a part of the GNU Project.
To use GNOME, add this to your configuration.nix:
services.xserver.enable = true; services.xserver.displayManager.gdm.enable = true; services.xserver.desktopManager.gnome.enable = true;
Excluding some GNOME applications from the default install
Not all applications that come pre-installed with the GNOME desktop environment are desirable for everyone to have on their machines. There's a way to edit
configuration.nix to exclude these kinds of packages, for example as follows:
environment.gnome.excludePackages = (with pkgs; [ gnome-photos gnome-tour ]) ++ (with pkgs.gnome; [ cheese # webcam tool gnome-music gnome-terminal gedit # text editor epiphany # web browser geary # email reader evince # document viewer gnome-characters totem # video player tali # poker game iagno # go game hitori # sudoku game atomix # puzzle game ]);
Running GNOME programs outside of GNOME
While we are packaging GNOME platform-based applications to be largely self-contained, they still depend, for one reason or another, on some global configuration. The
gnome.nix module sets all the necessary options for you but if you are running customized set-up, you might need to replicate that yourself.
For instance, if you see the following error:
dconf-WARNING **: failed to commit changes to dconf: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name ca.desrt.dconf was not provided by any .service files
you should enable dconf module:
programs.dconf.enable = true;
Many applications rely heavily on having an icon theme available, GNOME’s Adwaita is a good choice but most recent icon themes should work as well.
environment.systemPackages = [ gnome.adwaita-icon-theme ];
To get systray icons, install the related gnome shell extension
environment.systemPackages = with pkgs; [ gnomeExtensions.appindicator ];
And ensure gnome-settings-daemon udev rules are enabled :
services.udev.packages = with pkgs; [ gnome.gnome-settings-daemon ];
Running ancient applications
Long ago, in the GNOME 2 era, applications used GConf service to store configuration. This has been deprecated for many years but some applications were abandoned before they managed to upgrade to a newer dconf system. If you are running such application and getting an error like:
GLib.GException: Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information
you need to add
gnome2.GConf to the list of dbus packages in your
services.dbus.packages = with pkgs; [ gnome2.GConf ];
After applying the update one also has restart their desktop session to refresh the user-specific dbus session.
Change user's profile picture
Currently there is no way to change the user's profile picture using Gnome Control Center (see this issue) and currently there is no plan to support it officially in NixOS. However, you can modify it by copying the profile picture that you want to the path /var/lib/AccountsService/icons/$USER as a workaround, i.e.
cp /path/to/image.jpg /var/lib/AccountsService/icons/$USER
