Icons
GTK
By default, GTK-based applications try to use the Adwaita icon theme for
application icons. Consequently, installation of the gtk+3 package will also
install the adwaita-icon-theme package. If you wish to use a different theme,
install the relevant package, then specify the theme in
/etc/gtk-3.0/settings.ini or ~/.config/gtk-3.0/settings.ini.
adwaita-icon-theme can be removed after
ignoring the package.
For information about how to specify a different GTK icon theme in
settings.ini, refer to the GtkSettings
documentation,
in particular the
"gtk-icon-theme-name"
property.
