Xfce Installation

Xfce is a lightweight Linux desktop. In the current version, all components have been updated from GTK2 to GTK3 and from D-Dbus Glib to GDBus. Most components support GObject Introspection (GI), which is used to generate and parse the API meta information of the C program library, so that the dynamic language (or managed language) can be bound to the program library based on C + GObject. In the current version, user experience is optimized, new features are added, and a large number of bugs are fixed. Xfce occupies fewer memory and CPU resources than other UIs (GNOME and KDE), providing smoother and more efficient user experience.

Xfce supports the x86_64 and AArch64 architectures.

You are advised to create an administrator during the installation.

6. Set Xfce as the default desktop. Run the command as the root user.

   echo 'user-session=xfce' >> /etc/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf

10. FAQs

Why Is the Background Color of the LightDM Login Page Black?

The login page is black because background is not set in the default configuration file /etc/lightdm/lightdm-gtk-greeter.conf of lightdm-gtk. Set background=/usr/share/backgrounds/xfce/xfce-blue.jpg in the greeter section at the end of the configuration file, and then run the systemctl restart lightdm command.
