The screensaver application allows users to choose one or more screensaver displays. A screensaver display is an application that displays images on the screen of the user when the screen is not in use. The screensaver displays are listed in the XScreenSaver file and in the $HOME/.xscreensaver file.
To add a new screensaver display, copy the executable file for the display to the /usr/openwin/lib/xscreensaver/hacks directory. Add the command for the screensaver display to the XScreenSaver file or the $HOME/.xscreensaver file. Include any arguments that are required to run the screensaver display on the whole screen, rather than in a window. For example, you might want to include the -root option to display the screensaver display on the whole screen.
To add a new screensaver display, copy the executable file for the display to the /usr/X11R6/lib/xscreensaver/hacks directory. Add the command for the screensaver display to the XScreenSaver file or the $HOME/.xscreensaver file. Include any arguments that are required to run the screensaver display on the whole screen, rather than in a window. For example, you might want to include the -root option to display the screensaver display on the whole screen.
To disable a screensaver display, add a minus sign (-) at the start of the command for the screensaver display in the preferences file. The following excerpt from a $HOME/.xscreensaver file shows a disabled Qix (solid) screensaver display:
- "Qix (solid)" qix -root -solid -segments 100
To disable screensaver displays for all users on a Sun Ray™ thin 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 desktop environment of the user. To avoid security violations, screensaver displays that show the contents of the desktop environment are not included in the Sun Microsystems distribution of the GNOME Desktop.
The Pluggable Authentication Modules (PAM) service name
for the XScreenSaver
application is dtsession. This name is used to be compatible with previous applications.
