What is Xfce?
Xfce is a Desktop Environment, like GNOME or KDE. It contains a suite of apps like a root window app, window manager, file manager, panel, etc. Xfce is written using the GTK2 toolkit, and contains its own development environment (libraries, daemons, etc), similar to other big DEs. Unlike GNOME or KDE, Xfce is lightweight and designed more around CDE than Windows or Mac. It has a much slower development cycle, but is very stable and extremely fast. Xfce is great for older hardware.
Why use Xfce?
Here is a (subjective) list of reasons to use Xfce:
- It's fast, faster than the other major DEs.
- It's stable. In the long time Xfce-4 has been out, only a small handful of bugs has been discovered, despite it having a rather large following.
- It's pretty. It uses GTK2 and is themable. You can make Xfce look very nice. The fonts are completely AA as well.
- It works great with multiple monitors. Xfce's Xinerama support is the best out of any WM/DE, IMO.
- It doesn't get in your way. You'll find Xfce helps your work flow, rather than always making itself "present."
- It comes with a built-in compositor which allows for true transparency among other cool things.
Why not use Xfce?
Here is a (subjective) list of reasons not to use Xfce:
- Doesn't contain all the features and integration of the major DEs.
- Slower development cycle.
- Because it's based on the CDE design, the layout may not be as familiar.
How to Install Xfce
The Xfce source and documentation are available at http://www.xfce.org/. But since you're using ArchLinux, you can grab Xfce from Pacman.
Xfce is modular. That means there is no need for you to run every part, you can pick and choose. Because of this, Xfce has a bunch of Arch packages.
To install the base Xfce4 system, run:
# pacman -S xfce4
If you want extras, like Panel plugins and extra themes, (you probably do), run this:
# pacman -S xfce4-goodies gtk2-themes-collection
If you want to be able to play sound files, you should also install ESD, which acts as the Xfce sound daemon. (Or you can install xfmedia, the default Xfce media player, and it will pull ESD as a dependency.)
# pacman -S esd
Note that after installing Xfce, you need to update your $PATH. You can do this (for example) by logging in again.
There are two ways to run Xfce4. One is the "automatic" method. To start Xfce from the console, you can simply run:
Note: startxfce4 sets DPI to 96 by default, so font sizes will be different than when starting from .xinitrc.
To customize the Xfce startup using this method, you'll copy /opt/xfce4/etc/xdm/xfce4/xinitrc (/opt/xfce4/etc/xdg/xfce4/xinitrc instead for me using Noodle release) to $HOME/.xfce4, and edit that file To add programs to the startup up using this method, add symlinks from the programs you want to $HOME/Desktop/Autostart.
If you want more control over what starts and your initial settings, you can add these items to your $HOME/.xinitrc (leaving out and adding what you want):
xfce-mcs-manager xfwm4 --daemon xfdesktop & exec xfce4-panel
How To Use Xfce With DM's
As of Xfce 4.2.0, the Arch packages add the proper session files for Xfce. They are contained in the xfce-utils package, which should be installed with a base installation. Simply Enable a DM.
How to shutdown and reboot from Xfce
NOTE: It is no longer necessary (XFCE >= 4.4) to use SUDO to enable shutdown and reboot for normal users, therefore, if you enable the DBUS and HAL daemon's, you can skip this section. XFCE now utilizes DBUS. Make sure DBUS and HAL are enabled at boot (these can be added to the daemon array in /etc/rc.conf) and voila, you should be able to select the shutdown/reboot options from within XFCE. Also note that running DBUS and HAL will also enable you to automount optical or external media! To make the best use of this, install thunar-volman.
NOTE: I find that adding myself to the power group clears up this issue entirely.
# gpasswd -a USER power
- Install sudo:
# pacman -S sudo
- Add the following line at the end of
/etc/sudoersfile with visudo command:
- Note that the new Xfce packages in the 'extra' repository now place Xfce under '/usr'.
user ALL=(root) NOPASSWD: /usr/lib/xfce4/xfsm-shutdown-helper
where 'user' is the name of the user you want to allow to shutdown and reboot pc from Xfce.
Alternatively you can create shutdown group and allow all its members to shutdown:
%shutdown ALL=(root) NOPASSWD: /usr/lib/xfce4/xfsm-shutdown-helper
# groupadd shutdown # gpasswd -a user shutdown
where 'user' is name of the user.
To allow all users to be able to shutdown system add this to /etc/sudoers:
Where hostname is the name of current machine.
Commands for the settings manager
There is no official documentation for the commands executed. One must look at .desktop files /usr/share/applications/ folder. For the people who like to know exactly what is happening, here is a handy list to save the effort:
xfce-setting-show backdrop xfce-setting-show display xfce-setting-show keyboard xfce4-menueditor xfce-setting-show sound xfce-setting-show mouse xfce-setting-show session xfce-setting-show xfce-setting-show splash xfce-setting-show ui xfce-setting-show xfwm4 xfce-setting-show wmtweaks xfce-setting-show workspaces xfce-setting-show printing_system xfce4-appfinder xfce4-autostart-editor xfce4-panel -c
How to enable the compositor in Xfce 4.4+
Xfce 4.4 comes with a builtin compositor adding the option for fancy window effects, shadows and transparency and so on.
You can find it in Settings->Window manager tweaks. But if it isn't there, take the following steps:
- Open up $HOME/.config/xfce4/mcs_settings/wmtweaks.xml, and ensure that <option name="Xfwm/UseCompositing" type="int" value="1"/> is present. If the wmtweaks file is not there, open up the Settings->Window manager tweaks and change some things, then close it, and the file should appear.
- Make sure the following lines are in your /etc/X11/xorg.conf file:
Section "Extensions" Option "Composite" "Enable" EndSection
- Finally, restart X and the compositor should be available.
Why doesn't my desktop refresh?
XFCE 4.4 uses FAM (File Alteration Monitor) to get notification when a file or directory changes. Don't forget to add 'fam' to the list of DAEMONS in /etc/rc.conf
