Improving Performance - Novell LINUX ENTERPRISE DESKTOP 10 SP2 - DEPLOYMENT GUIDE 08-05-2008 Deployment Manual

To restore the default session settings for a user, delete the session file from the home
directory of the user. If no user session file is present, the default settings in /opt/
gnome/share/gnome/default.session are used.
To save the current session as the default session, users can run the
gnome-session-save command.
GNOME also supports autostart. For more information, see Section 10.12, "Starting
Applications Automatically" (page 283).

10.8 Improving Performance

This section discusses several preference settings you can change to improve the per-
formance of the GNOME Desktop. You can use the gconftool-2 command to set values

You can also use the --direct and --config-source options to set mandatory
values or default values for preferences. And you can use the gconftool-2 command in
a script to set the values of many preferences. For more information on the gconftool-
2 command and the options that are available with the command, see Section 10.1,
