Installation

Fedora:
sudo dnf copr enable monday15/lounge
sudo dnf install lounge-gtk-theme
or
sudo dnf install lounge-gtk-theme-xfce-sway for xfce/sway users.

Lounge-aux-icon-theme comes as a weak dependency, with Adwaita as a main icon theme. Lounge-backgrounds is also a recommended dependency.

Ubuntu:
sudo add-apt-repository ppa:monday15/lounge
sudo apt install lounge-gtk-theme
or
sudo apt install lounge-gtk-theme-xfce-sway for xfce/sway users.

Lounge-aux-icon-theme comes as a weak dependency, with Adwaita as a main icon theme. Lounge-backgrounds is also a recommended dependency.

Flatpak

Flatpak apps support available via Flathub:
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.gtk.Gtk3theme.Lounge
flatpak install flathub org.gtk.Gtk3theme.Lounge-night
flatpak install flathub org.gtk.Gtk3theme.Lounge-compact
flatpak install flathub org.gtk.Gtk3theme.Lounge-night-compact

If you want to use the theme built with custom options for flatpak apps, you can install default flatpak package and copy files from you variant of the theme to flatpak folder. Default location for flatpak packages is /var/lib/flatpak/..., full command will look something like sudo cp -r /usr/share/themes/Lounge/gtk-3.0/* /var/lib/flatpak/runtime/org.gtk.Gtk3theme.Lounge/x86_64/3.22/active/files/. Note, that flatpak supports only gtk3 themes.

meson (0.45+)

  (availiable options screenshot)

  Option	Default value	Other values	Description
  tone	tango	salsa rumba jive	Color scheme
  style	prime	flat	Theme style (only for gtk2/gtk3)
  scale_style	casual	fancy	Scales and progressbars style (only for gtk2/gtk3)
  scrollbar_handles	no_handles	with_handles	Handles on scrollbars
  button_outlines	strong	bright	Focus outline color on regular buttons in a light theme (only for gtk3)
  shell_font	Roboto	any font	Set font for gnome-shell theme
  gtk2_solid_menu	false	true	Use solid border for menus in gtk2 theme - highly recommended option for XFCE/Sway users, but looks bad in GNOME, screenshot from XFCE
  icons	true	false	Build auxiliary icon theme
  icon_theme	Adwaita	any theme	Set main icon theme for auxiliary one
  gnome_version	auto	3.28 - 3.34	Affects only gnome-shell theme and nautilus style. Meson detect gnome version automatically based on gnome-shell version, if there is no gnome-shell and you plan to use nautilus file manager - you need to set version manually, so correct style will be used.

  For example, meson build -Dtone=salsa -Dscale_style=fancy -Dshell-font='Liberation Sans'
  builds the theme with purple accent colors, colored scales/progressbars, and with Liberation Sans font in gnome-shell.

• Install theme:
  sudo ninja -C build install
