|The X display to use. For displays with multiple screens, XScreenSaver will manage all screens on the display simultaniously.|
|-verbose||Same as setting the verbose resource to true: print diagnostics on stderr and on the xscreensaver window.|
|Do not redirect the stdout and stderr streams to the xscreensaver window itself. If xscreensaver is crashing, you might need to do this in order to see the error message.|
|This is exactly the same as redirecting stdout and stderr to the given file (for append). This is useful when reporting bugs.|
When it is time to activate the screensaver, a full-screen black window is created on each screen of the display. Each window is created in such a way that, to any subsequently-created programs, it will appear to be a virtual root window. Because of this, any program which draws on the root window (and which understands virtual roots) can be used as a screensaver. The various graphics demos are, in fact, just standalone programs that know how to draw on the provided window.
When the user becomes active again, the screensaver windows are unmapped, and the running subprocesses are killed by sending them SIGTERM. This is also how the subprocesses are killed when the screensaver decides that its time to run a different demo: the old one is killed and a new one is launched.
You can control a running screensaver process by using the xscreensaver-command(1) program (which see.)
Modern X servers contain support to power down the monitor after an idle period. If the monitor has powered down, then xscreensaver will notice this (after a few minutes), and will not waste CPU by drawing graphics demos on a black screen. An attempt will also be made to explicitly power the monitor back up as soon as user activity is detected.
The ~/.xscreensaver file controls the configuration of your displays power management settings: if you have used xset(1) to change your power management settings, then xscreensaver will override those changes with the values specified in ~/.xscreensaver (or with its built-in defaults, if there is no ~/.xscreensaver file yet.)
To change your power management settings, run xscreensaver-demo(1) and change the various timeouts through the user interface. Alternately, you can edit the ~/.xscreensaver file directly.
If the power management section is grayed out in the xscreensaver-demo(1) window, then that means that your X server does not support the XDPMS extension, and so control over the monitors power state is not available.
If youre using a laptop, dont be surprised if changing the DPMS settings has no effect: many laptops have monitor power-saving behavior built in at a very low level that is invisible to Unix and X. On such systems, you can typically adjust the power-saving delays only by changing settings in the BIOS in some hardware-specific way.
If DPMS seems not to be working with XFree86, make sure the "DPMS" option is set in your /etc/X11/XF86Config file. See the XF86Config(5) manual for details.
For many years, GNOME shipped xscreensaver as-is, and everything just worked out of the box. Recently, however, theyve been re-inventing the wheel again in the form of "gnome-screensaver".
To replace gnome-screensaver with xscreensaver:
1: Turn off gnome-screensaver. Open System / Preferences / Screensaver and uncheck both boxes. 2: Stop gnome-screensaver from launching at login. Run the command:
gconftool-2 --type boolean -s \ /apps/gnome_settings_daemon/screensaver/start_screensaver \ false
Or, just uninstall the "gnome-screensaver" package entirely.
3: Launch xscreensaver at login. Open System / Preferences / Sessions / Startup Programs. Click Add and type xscreensaver. 4: Tell Preferences to use the xscreensaver configurator. Edit /usr/share/applications/gnome-screensaver-preferences.desktop and change the Exec= line to say
5: Make System / Quit / Lock Screen use xscreensaver. Run the command:
sudo ln -sf /usr/bin/xscreensaver-command \ /usr/bin/gnome-screensaver-command
KDE also has invented their own screen saver framework instead of simply using xscreensaver. To replace the KDE screen saver with xscreensaver, do the following:
1: Turn off KDEs screen saver. Open the Control Center and select the Appearance & Themes / Screensaver page. Un-check Start Automatically. 2: Find your Autostart directory. Open the System Administration -> Paths page, and see what your Autostart path is set to: it will probably be ~/.kde/Autostart/ or something similar. 3: Make xscreensaver be an Autostart program. Create a .desktop file in your autostart directory called xscreensaver.desktop that contains the following five lines:
[Desktop Entry] Exec=xscreensaver Name=XScreenSaver Type=Application X-KDE-StartupNotify=false
4: Make the various "lock session" buttons call xscreensaver. Replace the file kdesktop_lock or krunner_lock or kscreenlocker in /usr/bin/ (or possibly in /usr/kde/3.5/bin/ or possibly in /usr/lib/kde4/libexec/ or /usr/libexec/kde4/, depending on the distro and phase of the moon) with these two lines:
#!/bin/sh xscreensaver-command -lock
Make sure the file is executable (chmod a+x).
You can run xscreensaver from your gdm(1) session, so that the screensaver will run even when nobody is logged in on the console. To do this, run gdmconfig(1) and on the Background page, type the command "xscreensaver -nosplash" into the Background Program field. That will cause gdm to run xscreensaver while nobody is logged in, and kill it as soon as someone does log in. (The user will then be responsible for starting xscreensaver on their own, if they want.)
Another way to accomplish the same thing is to edit the file /etc/X11/gdm/gdm.conf to include:
BackgroundProgram=xscreensaver -nosplash RunBackgroundProgramAlways=true
In this situation, the xscreensaver process will probably be running as user gdm instead of root. You can configure the settings for this nobody-logged-in state (timeouts, DPMS, etc.) by editing the ~gdm/.xscreensaver file.
To get gdm to run the BackgroundProgram, you may need to switch it from the "Graphical Greeter" to the "Standard Greeter".
It is safe to run xscreensaver as root (as xdm is likely to do.) If run as root, xscreensaver changes its effective user and group ids to something safe (like "nobody") before connecting to the X server or launching user-specified programs.
An unfortunate side effect of this (important) security precaution is that it may conflict with cookie-based authentication.
If you get "connection refused" errors when running xscreensaver from gdm, then this probably means that you have xauth(1) or some other security mechanism turned on. For information on the X servers access control mechanisms, see the man pages for X(1), Xsecurity(1), xauth(1), and xhost(1).
Bugs? There are no bugs. Ok, well, maybe. If you find one, please let me know. http://www.jwz.org/xscreensaver/bugs.html explains how to construct the most useful bug reports.
Locking and XDM If xscreensaver has been launched from xdm(1) before anyone has logged in, you will need to kill and then restart the xscreensaver daemon after you have logged in, or you will be confused by the results. (For example, locking wont work, and your ~/.xscreensaver file will be ignored.)
When you are logged in, you want the xscreensaver daemon to be running under your user id, not as root or some other user.
If it has already been started by xdm, you can kill it by sending it the exit command, and then re-launching it as you, by putting something like the following in your personal X startup script:
xscreensaver-command -exit xscreensaver &
The Using XDM(1) section, above, goes into more detail, and explains how to configure the system to do this for all users automatically.
Locking and root logins In order for it to be safe for xscreensaver to be launched by xdm, certain precautions had to be taken, among them that xscreensaver never runs as root. In particular, if it is launched as root (as xdm is likely to do), xscreensaver will disavow its privileges, and switch itself to a safe user id (such as nobody.)
An implication of this is that if you log in as root on the console, xscreensaver will refuse to lock the screen (because it cant tell the difference between root being logged in on the console, and a normal user being logged in on the console but xscreensaver having been launched by the xdm(1) Xsetup file.)
The solution to this is simple: you shouldnt be logging in on the console as root in the first place! (What, are you crazy or something?)
Proper Unix hygiene dictates that you should log in as yourself, and su(1) to root as necessary. People who spend their day logged in as root are just begging for disaster.
XAUTH and XDM For xscreensaver to work when launched by xdm(1), programs running on the local machine as user "nobody" must be able to connect to the X server. This means that if you want to run xscreensaver on the console while nobody is logged in, you may need to disable cookie-based access control (and allow all users who can log in to the local machine to connect to the display.)
You should be sure that this is an acceptable thing to do in your environment before doing it. See the Using XDM(1) section, above, for more details.
Passwords If you get an error message at startup like couldnt get password of user then this probably means that youre on a system in which the getpwent(3) library routine can only be effectively used by root. If this is the case, then xscreensaver must be installed as setuid to root in order for locking to work. Care has been taken to make this a safe thing to do.
It also may mean that your system uses shadow passwords instead of the standard getpwent(3) interface; in that case, you may need to change some options with configure and recompile.
If you change your password after xscreensaver has been launched, it will continue using your old password to unlock the screen until xscreensaver is restarted. On some systems, it may accept both your old and new passwords. So, after you change your password, youll have to do
to make xscreensaver notice.
PAM Passwords If your system uses PAM (Pluggable Authentication Modules), then in order for xscreensaver to use PAM properly, PAM must be told about xscreensaver. The xscreensaver installation process should update the PAM data (on Linux, by creating the file /usr/local/etc/pam.d/xscreensaver for you, and on Solaris, by telling you what lines to add to the /etc/pam.conf file.)
If the PAM configuration files do not know about xscreensaver, then you might be in a situation where xscreensaver will refuse to ever unlock the screen.
This is a design flaw in PAM (there is no way for a client to tell the difference between PAM responding I have never heard of your module, and responding, you typed the wrong password.) As far as I can tell, there is no way for xscreensaver to automatically work around this, or detect the problem in advance, so if you have PAM, make sure it is configured correctly!
Machine Load Although this program nices the subprocesses that it starts, graphics-intensive subprograms can still overload the machine by causing the X server process itself (which is not niced) to consume many cycles. Care has been taken in all the modules shipped with xscreensaver to sleep periodically, and not run full tilt, so as not to cause appreciable load.
However, if you are running the OpenGL-based screen savers on a machine that does not have a video card with 3D acceleration, they will make your machine slow, despite nice(1).
Your options are: dont use the OpenGL display modes; or, collect the spare change hidden under the cushions of your couch, and use it to buy a video card manufactured after 1998. (It doesnt even need to be fast 3D hardware: the problem will be fixed if there is any 3D hardware at all.)
XFree86s Magic Keystrokes The XFree86 X server traps certain magic keystrokes before client programs ever see them. Two that are of note are Ctrl+Alt+Backspace, which causes the X server to exit; and Ctrl+Alt+Fn, which switches virtual consoles. The X server will respond to these keystrokes even if xscreensaver has the screen locked. Depending on your setup, you might consider this a problem.
Unfortunately, there is no way for xscreensaver itself to override the interpretation of these keys. If you want to disable Ctrl+Alt+Backspace globally, you need to set the DontZap flag in your /etc/X11/XF86Config file. To globally disable VT switching, you can set the DontVTSwitch flag. See the XF86Config(5) manual for details.
These are the X resources use by the xscreensaver program. You probably wont need to change these manually (thats what the xscreensaver-demo(1) program is for).
timeout (class Time) The screensaver will activate (blank the screen) after the keyboard and mouse have been idle for this many minutes. Default 10 minutes. cycle (class Time) After the screensaver has been running for this many minutes, the currently running graphics-hack sub-process will be killed (with SIGTERM), and a new one started. If this is 0, then the graphics hack will never be changed: only one demo will run until the screensaver is deactivated by user activity. Default 10 minutes. lock (class Boolean) Enable locking: before the screensaver will turn off, it will require you to type the password of the logged-in user (really, the person who ran xscreensaver), or the root password. (Note: this doesnt work if the screensaver is launched by xdm(1) because it cant know the user-id of the logged-in user. See the Using XDM(1) section, below. lockTimeout (class Time) If locking is enabled, this controls the length of the grace period between when the screensaver activates, and when the screen becomes locked. For example, if this is 5, and -timeout is 10, then after 10 minutes, the screen would blank. If there was user activity at 12 minutes, no password would be required to un-blank the screen. But, if there was user activity at 15 minutes or later (that is, -lock-timeout minutes after activation) then a password would be required. The default is 0, meaning that if locking is enabled, then a password will be required as soon as the screen blanks. passwdTimeout (class Time) If the screen is locked, then this is how many seconds the password dialog box should be left on the screen before giving up (default 30 seconds.) This should not be too large: the X server is grabbed for the duration that the password dialog box is up (for security purposes) and leaving the server grabbed for too long can cause problems. dpmsEnabled (class Boolean) Whether power management is enabled. dpmsStandby (class Time) If power management is enabled, how long until the monitor goes solid black. dpmsSuspend (class Time) If power management is enabled, how long until the monitor goes into power-saving mode. dpmsOff (class Time) If power management is enabled, how long until the monitor powers down completely. Note that these settings will have no effect unless both the X server and the display hardware support power management; not all do. See the Power Management section, below, for more information. visualID (class VisualID) Specify which X visual to use by default. (Note carefully that this resource is called visualID, not merely visual; if you set the visual resource instead, things will malfunction in obscure ways for obscure reasons.)
Legal values for the VisualID resource are:
Note that this option specifies only the default visual that will be used: the visual used may be overridden on a program-by-program basis. See the description of the programs resource, below.
default Use the screens default visual (the visual of the root window.) This is the default. best Use the visual which supports the most colors. Note, however, that the visual with the most colors might be a TrueColor visual, which does not support colormap animation. Some programs have more interesting behavior when run on PseudoColor visuals than on TrueColor. mono Use a monochrome visual, if there is one. gray Use a grayscale or staticgray visual, if there is one and it has more than one plane (that is, its not monochrome.) color Use the best of the color visuals, if there are any. GL Use the visual that is best for OpenGL programs. (OpenGL programs have somewhat different requirements than other X programs.) class where class is one of StaticGray, StaticColor, TrueColor, GrayScale, PseudoColor, or DirectColor. Selects the deepest visual of the given class. number where number (decimal or hex) is interpreted as a visual id number, as reported by the xdpyinfo(1) program; in this way you can have finer control over exactly which visual gets used, for example, to select a shallower one than would otherwise have been chosen.
installColormap (class Boolean) On PseudoColor (8-bit) displays, install a private colormap while the screensaver is active, so that the graphics hacks can get as many colors as possible. This is the default. (This only applies when the screens default visual is being used, since non-default visuals get their own colormaps automatically.) This can also be overridden on a per-hack basis: see the discussion of the default-n name in the section about the programs resource.
This does nothing if you have a TrueColor (16-bit or deeper) display.
verbose (class Boolean) Whether to print diagnostics. Default false. timestamp (class Boolean) Whether to print the time of day along with any other diagnostic messages. Default true. splash (class Boolean) Whether to display a splash screen at startup. Default true. splashDuration (class Time) How long the splash screen should remain visible; default 5 seconds. helpURL (class URL) The splash screen has a Help button on it. When you press it, it will display the web page indicated here in your web browser. loadURL (class LoadURL) This is the shell command used to load a URL into your web browser. The default setting will load it into Mozilla/Netscape if it is already running, otherwise, will launch a new browser looking at the helpURL. demoCommand (class DemoCommand) This is the shell command run when the Demo button on the splash window is pressed. It defaults to xscreensaver-demo(1). prefsCommand (class PrefsCommand) This is the shell command run when the Prefs button on the splash window is pressed. It defaults to xscreensaver-demo -prefs. nice (class Nice) The sub-processes created by xscreensaver will be niced to this level, so that they are given lower priority than other processes on the system, and dont increase the load unnecessarily. The default is 10.
(Higher numbers mean lower priority; see nice(1) for details.)
fade (class Boolean) If this is true, then when the screensaver activates, the current contents of the screen will fade to black instead of simply winking out. This only works on certain systems. A fade will also be done when switching graphics hacks (when the cycle timer expires.) Default: true. unfade (class Boolean) If this is true, then when the screensaver deactivates, the original contents of the screen will fade in from black instead of appearing immediately. This only works on certain systems, and if fade is true as well. Default false. fadeSeconds (class Time) If fade is true, this is how long the fade will be in seconds (default 3 seconds.) fadeTicks (class Integer) If fade is true, this is how many times a second the colormap will be changed to effect a fade. Higher numbers yield smoother fades, but may make the fades take longer than the specified fadeSeconds if your server isnt fast enough to keep up. Default 20. captureStderr (class Boolean) Whether xscreensaver should redirect its stdout and stderr streams to the window itself. Since its nature is to take over the screen, you would not normally see error messages generated by xscreensaver or the sub-programs it runs; this resource will cause the output of all relevant programs to be drawn on the screensaver window itself, as well as being written to the controlling terminal of the screensaver driver process. Default true. ignoreUninstalledPrograms (class Boolean) There may be programs in the list that are not installed on the system, yet are marked as "enabled." If this preference is true, then such programs will simply be ignored. If false, then a warning will be printed if an attempt is made to run the nonexistent program. Also, the xscreensaver-demo(1) program will suppress the non-existent programs from the list if this is true. Default: false. GetViewPortIsFullOfLies (class Boolean) Set this to true if the xscreensaver window doesnt cover the whole screen. This works around a longstanding XFree86 bug #421. See the xscreensaver FAQ for details. font (class Font) The font used for the stdout/stderr text, if captureStderr is true. Default *-medium-r-*-140-*-m-* (a 14 point fixed-width font.) mode (class Mode) Controls the behavior of xscreensaver. Legal values are:
random When blanking the screen, select a random display mode from among those that are enabled and applicable. This is the default. random-same Like random, but if there are multiple screens, each screen will run the same random display mode, instead of each screen running a different one. one When blanking the screen, only ever use one particular display mode (the one indicated by the selected setting.) blank When blanking the screen, just go black: dont run any graphics hacks. off Dont ever blank the screen, and dont ever allow the monitor to power down.
selected (class Integer) When mode is set to one, this is the one, indicated by its index in the programs list. Youre crazy if you count them and set this number by hand: let xscreensaver-demo(1) do it for you! programs (class Programs) The graphics hacks which xscreensaver runs when the user is idle. The value of this resource is a multi-line string, one sh-syntax command per line. Each line must contain exactly one command: no semicolons, no ampersands.
When the screensaver starts up, one of these is selected (according to the mode setting), and run. After the cycle period expires, it is killed, and another is selected and run.
If a line begins with a dash (-) then that particular program is disabled: it wont be selected at random (though you can still select it explicitly using the xscreensaver-demo(1) program.)
If all programs are disabled, then the screen will just be made blank, as when mode is set to blank.
To disable a program, you must mark it as disabled with a dash instead of removing it from the list. This is because the system-wide (app-defaults) and per-user (.xscreensaver) settings are merged together, and if a user just deletes an entry from their programs list, but that entry still exists in the system-wide list, then it will come back. However, if the user disables it, then their setting takes precedence.
If the display has multiple screens, then a different program will be run for each screen. (All screens are blanked and unblanked simultaneously.)
Note that you must escape the newlines; here is an example of how you might set this in your ~/.xscreensaver file:
programs: \ qix -root \n\ ico -r -faces -sleep 1 -obj ico \n\ xdaliclock -builtin2 -root \n\ xv -root -rmode 5 image.gif -quit \n
Make sure your $PATH environment variable is set up correctly before xscreensaver is launched, or it wont be able to find the programs listed in the programs resource.
To use a program as a screensaver, two things are required: that that program draw on the root window (or be able to be configured to draw on the root window); and that that program understand virtual root windows, as used by virtual window managers such as tvtwm(1). (Generally, this is accomplished by just including the "vroot.h" header file in the programs source.)
If there are some programs that you want to run only when using a color display, and others that you want to run only when using a monochrome display, you can specify that like this:
mono: mono-program -root \n\ color: color-program -root \n\
More generally, you can specify the kind of visual that should be used for the window on which the program will be drawing. For example, if one program works best if it has a colormap, but another works best if it has a 24-bit visual, both can be accommodated:
PseudoColor: cmap-program -root \n\ TrueColor: 24bit-program -root \n\
In addition to the symbolic visual names described above (in the discussion of the visualID resource) one other visual name is supported in the programs list:
If you specify a particular visual for a program, and that visual does not exist on the screen, then that program will not be chosen to run. This means that on displays with multiple screens of different depths, you can arrange for appropriate hacks to be run on each. For example, if one screen is color and the other is monochrome, hacks that look good in mono can be run on one, and hacks that only look good in color will show up on the other.
default-n This is like default, but also requests the use of the default colormap, instead of a private colormap. (That is, it behaves as if the -no-install command-line option was specified, but only for this particular hack.) This is provided because some third-party programs that draw on the root window (notably: xv(1), and xearth(1)) make assumptions about the visual and colormap of the root window: assumptions which xscreensaver can violate.
You shouldnt ever need to change the following resources: pointerPollTime (class Time) When server extensions are not in use, this controls how frequently xscreensaver checks to see if the mouse position or buttons have changed. Default 5 seconds. pointerHysteresis (class Integer) If the mouse moves less than this-many pixels in a second, ignore it (do not consider that to be "activity.") This is so that the screen doesnt un-blank (or fail to blank) just because you bumped the desk. Default: 10 pixels. windowCreationTimeout (class Time) When server extensions are not in use, this controls the delay between when windows are created and when xscreensaver selects events on them. Default 30 seconds. initialDelay (class Time) When server extensions are not in use, xscreensaver will wait this many seconds before selecting events on existing windows, under the assumption that xscreensaver is started during your login procedure, and the window state may be in flux. Default 0. (This used to default to 30, but that was back in the days when slow machines and X terminals were more common...)
There are a number of different X server extensions which can make xscreensavers job easier. The next few resources specify whether these extensions should be utilized if they are available.
|sgiSaverExtension (class Boolean)|
|This resource controls whether the SGI SCREEN_SAVER server extension will be used to decide whether the user is idle. This is the default if xscreensaver has been compiled with support for this extension (which is the default on SGI systems.). If it is available, the SCREEN_SAVER method is faster and more reliable than what will be done otherwise, so use it if you can. (This extension is only available on Silicon Graphics systems, unfortunately.)|
|mitSaverExtension (class Boolean)|
|This resource controls whether the MIT-SCREEN-SAVER server extension will be used to decide whether the user is idle. However, the default for this resource is false, because even if this extension is available, it is flaky (and it also makes the fade option not work properly.) Use of this extension is strongly discouraged. Support for it will probably be removed eventually.|
|xidleExtension (class Boolean)|
|This resource controls whether the XIDLE server extension will be used to decide whether the user is idle. This is the default if xscreensaver has been compiled with support for this extension. (This extension is only available for X11R4 and X11R5 systems, unfortunately.)|
|procInterrupts (class Boolean)|
This resource controls whether the /proc/interrupts file should be
consulted to decide whether the user is idle. This is the default
if xscreensaver has been compiled on a system which supports this
mechanism (i.e., Linux systems.)
The benefit to doing this is that xscreensaver can note that the user is active even when the X console is not the active one: if the user is typing in another virtual console, xscreensaver will notice that and will fail to activate. For example, if youre playing Quake in VGA-mode, xscreensaver wont wake up in the middle of your game and start competing for CPU.
The drawback to doing this is that perhaps you really do want idleness on the X console to cause the X display to lock, even if there is activity on other virtual consoles. If you want that, then set this option to False. (Or just lock the X console manually.)
The default value for this resource is True, on systems where it works.
|overlayStderr (class Boolean)|
|If captureStderr is True, and your server supports overlay visuals, then the text will be written into one of the higher layers instead of into the same layer as the running screenhack. Set this to False to disable that (though you shouldnt need to.)|
|overlayTextForeground (class Foreground)|
|The foreground color used for the stdout/stderr text, if captureStderr is true. Default: Yellow.|
|overlayTextBackground (class Background)|
|The background color used for the stdout/stderr text, if captureStderr is true. Default: Black.|
|bourneShell (class BourneShell)|
|The pathname of the shell that xscreensaver uses to start subprocesses. This must be whatever your local variant of /bin/sh is: in particular, it must not be csh.|
DISPLAY to get the default host and display number, and to inform the sub-programs of the screen on which to draw. XSCREENSAVER_WINDOW Passed to sub-programs to indicate the ID of the window on which they should draw on. This is necessary on Xinerama/RANDR systems where multiple physical monitors share a single X11 "Screen". PATH to find the sub-programs to run. HOME for the directory in which to read the .xscreensaver file. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
