To disable screensaver displays for all users on a Sun RayTM client, rename the /usr/openwin/lib/xscreensaver/hacks directory to any name other than hacks.
OpenGL
screensaver displays are provided
with the GNOME Desktop. By default, all OpenGL
screensaver displays are disabled, because many users do not have the OpenGL
library installed. Users who have the OpenGL
library installed can use the XScreenSaver
dialog to enable OpenGL
screensaver displays.
Some screensaver displays show the contents of the screen of the user. To avoid security violations, screensaver displays that show the contents of the screen are not included in the Java Desktop System.
The Pluggable Authentication Modules (PAM)
service name for the XScreenSaver
application is dtsession. This name is used for compatibility with previous applications.
