GNOME Flashback

GNOME Flashback (previously called GNOME fallback mode) is a shell for GNOME 3. The desktop layout and the underlying technology is similar to GNOME 2. It doesn't use 3D acceleration at all, so it's generally faster and less CPU intensive than GNOME Shell with llvmpipe.

Note: GNOME Flashback is not fully compatible with GNOME 3.10 or later. See: [1]

Installation

GNOME Flashback can be installed from either the gnome-flashback or gnome-flashback-git packages, both of which are available in the AUR.

You can also install the following packages which provide some additional applets for the GNOME Panel:

To get a complete desktop environment, it's recommended to install the gnome group which contains applications required for the standard GNOME experience.

Starting

Graphical log-in

Choose GNOME Flashback (Metacity) from the menu in a display manager of choice.

Those who wish to use Compiz with GNOME Flashback should select GNOME Flashback (Compiz) instead.

Manually

  • For the GNOME Flashback (Metacity) session, add the following to the ~/.xinitrc file: exec gnome-session --session=gnome-flashback-metacity
  • For the GNOME Flashback (Compiz) session, add the following to the ~/.xinitrc file: exec gnome-session --session=gnome-flashback-compiz

After the exec command is placed, GNOME Flashback can be launched by typing startx. See xinitrc for details.

Configuration

GNOME Flashback shares most of its settings with GNOME. See Customizing GNOME appearance for more details.

Customizing GNOME Panel

  • To configure the panel, hold down the Alt key, and right-click on it in an empty area.
  • To move an applet on the panel, hold down the Alt key, and grab it with middle-button.
Note: If the Alt+right-click combination does not work, try Super+Alt+right-click instead.

Alternative window manager

You can use an alternative window manager with GNOME by creating two files:

Note: Xmonad is used as an example, but this works for other window managers.
/usr/share/gnome-session/sessions/gnome-xmonad.session
[GNOME Session]
Name=GNOME xmonad
RequiredComponents=gnome-panel;gnome-settings-daemon;gnome-screensaver;xmonad;notification-daemon;polkit-gnome-authentication-agent-1;gnome-fallback-background-helper;gnome-fallback-media-keys-helper;gnome-fallback-mount-helper;
/usr/share/xsessions/gnome-xmonad.desktop
[Desktop Entry]
Name=GNOME xmonad
Comment=This session logs you into GNOME with the traditional panel
Exec=gnome-session --session=gnome-xmonad
TryExec=gnome-session
Icon=
Type=Application

The next time you log in, you should have the ability to choose GNOME xmonad as your session.

If there isn't a .desktop file for the window manager, you'll need to create one. Example for wmii:

/usr/share/applications/wmii.desktop
[Desktop Entry]
Version=1.0
Type=Application
Name=wmii
TryExec=wmii
Exec=wmii

Using GNOME Panel with a standalone window manager

The GNOME Flashback experience is primarily provided by GNOME Panel. The other components are only required for the Flashback session itself. If you would like to use GNOME Panel without the Flashback session you can just install the gnome-panel package and autostart the panel with a standalone window manager such as Openbox.

For example: if you want to use GNOME Panel with Openbox add gnome-panel & to the ~/.config/openbox/autostart file.

See your window manager's wiki page as well as the Autostarting page for further instruction.

Known Issues

  • Fallback menus for applications with the GNOME header bar are not visible. See: [2]
