GNOME Flashback is a shell for GNOME 3 which was initially called GNOME fallback mode. 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 consumes less CPU time than GNOME Shell with llvmpipe.
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 thegroup which contains applications required for the standard GNOME experience.
Starting GNOME Flashback
Simply choose GNOME Flashback session from your favourite display manager.
Starting GNOME Flashback manually
If you prefer to start GNOME Flashback manually from the console, add the following line to your
exec gnome-session --session=gnome-flashback
exec command is placed, GNOME Flashback can be launched by typing
startx. See xinitrc for details.
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
Altkey, and right-click on it in an empty area.
- To move an applet on the panel, hold down the
Altkey, and grab it with middle-button.
Alternative window manager
You can use an alternative window manager with GNOME by creating two files:
[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;
[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:
[Desktop Entry] Version=1.0 Type=Application Name=wmii TryExec=wmii Exec=wmii
For more information, see this article on running awesome as the window manager in GNOME.
User Switching with LightDM
To enable user switching in Gnome Flashback with LightDM users need to create a symlink:
# ln -s /usr/lib/lightdm/lightdm/gdmflexiserver /usr/local/bin/gdmflexiserver

When used with Gnome 3.10 the mouse cursor is not visible. To correct this, in the dconf editor expand: org/gnome/settings-daemon/plugins and click on cursor. Uncheck the box labeled active.

- Logout and shutdown is not possible.
- The clock applet crashes when opening its settings.
- The desktop background image sometimes blanked out.
