Gruvbox GTK Theme

[!NOTE] Description A GTK theme based on the colours of Sainnhe's great theme: Gruvbox Material for Neovim, the VinceLiuice's awesome: Magnetic GTK theme and the creativity of Gusbemacbe's: Suru Plus Icon Theme.
Great to combine in your Gnome Desktop Environment and TWMs like: XmonadWM, AwesomeWM, BSPWM, etc...

The theme is more focused on the Gnome Desktop, but supports Cinnamon, XFCE, Mate, etc. with generic styles. It's great to combine in your TWMs like: XmonadWM, AwesomeWM, BSPWM, etc...

INSTALLING THEMES

Before installing the themes, make sure to install the following necessary packages: sassc murrine-engine and gnome-themes-extra packages for the correct rendering of themes.

Here are some commands to install on some distributions.

• On Fedora run:

 sudo dnf install gtk-murrine-engine

• On OpenSUSE run:

 sudo zypper install gtk2-engine-murrine

• On Arch run:

sudo pacman -S gtk-engine-murrine

• On Debian and derivatives run:

sudo apt install gtk2-engines-murrine

The themes work on versions 40 to 44 of the GNOME D.E. just follow the steps below for installation:

• Download the themes packs and extract them
• Move the extracted files to the following paths:
  • For GTK3: ~/.themes In this path you must move the entire theme folder.
  • For GTK4: ~/.config/gtk-4.0 The files to move to this path can be found inside the theme directory in the gtk-4.0 folder, copy only the assets, gtk.css and gtk-dark.css files or create a symlinks.

Applying Themes from zip files

• For GTK3, apply themes from Gnome Tweaks.
• For GTK4 applications it is only necessary to have moved the assets, gtk.css and gtk-dark.css files to the ~/.config/gtk-4.0 path, and if you notice that the theme has not been applied, just close and reopen the application.

Applying Themes to Flatpak Apps

• Override flatpak themes to ~/.themes:

sudo flatpak override --filesystem=$HOME/.themes

• Override flatpak icons to ~/.icons:

sudo flatpak override --filesystem=$HOME/.icons

• Override flatpak themes to ~/.config/gtk-4.0 locally:

flatpak override --user --filesystem=xdg-config/gtk-4.0

• Override flatpak themes to ~/.config/gtk-4.0 globally:

sudo flatpak override --filesystem=xdg-config/gtk-4.0
