.SH NAME
xscreensaver - graphics hack and screen locker, launched when the user is idle
.SH SYNOPSIS
.B color
Use the best of the color visuals, if there are any.
.TP 8
+.B GL
+Use the visual that is best for OpenGL programs. (OpenGL programs have
+somewhat different requirements than other X programs.)
+.TP 8
.I class
where \fIclass\fP is one of \fBStaticGray\fP, \fBStaticColor\fP,
\fBTrueColor\fP, \fBGrayScale\fP, \fBPseudoColor\fP, or \fBDirectColor\fP.
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.
.TP 8
.B overlayStderr\fP (class \fBBoolean\fP)
If \fBcaptureStderr\fP is True, and your server supports ``overlay'' visuals,
directly into the root menu.
.RE
-Other window managers are guaranteed to do things gratuitously differently.
+For Fvwm2, the process is similar: first create a \fI~/.fvwm2rc\fP file
+if you don't already have one, by making a copy of
+the \fI/etc/X11/fvwm2/system.fvwm2rc\fP file. Then, add a menu definition
+to it:
+.EX
+AddToMenu XScreenSaver "XScreenSaver" Title
++ "Blank Screen Now" Exec xscreensaver-command -activate
++ "Lock Screen Now" Exec xscreensaver-command -lock
++ "Screen Saver Demo" Exec xscreensaver-command -demo
++ "Screen Saver Preferences" Exec xscreensaver-command -prefs
++ "Reinitialize Screen Saver" Exec xscreensaver-command -restart
++ "Kill Screen Saver" Exec xscreensaver-command -exit
++ "Launch Screen Saver" Exec xscreensaver
++ "Run Next Demo" Exec xscreensaver-command -next
++ "Run Previous Demo" Exec xscreensaver-command -prev
+
+# To put the XScreenSaver sub-menu at the end of the root menu:
+AddToMenu RootMenu "XScreenSaver" Popup XScreenSaver
+.EE
+The Enlightenment window manager keeps each of its menus in a separate
+file. So, you need to create a file
+named \fI~/.enlightenment/xscreensaver.menu\fP with the contents:
+.EX
+"XScreenSaver Commands"
+ "Blank Screen Now" NULL exec "xscreensaver-command -activate"
+ "Lock Screen Now" NULL exec "xscreensaver-command -lock"
+ "Screen Saver Demo" NULL exec "xscreensaver-command -demo"
+ "Screen Saver Prefs" NULL exec "xscreensaver-command -prefs"
+ "Reinitialize Saver" NULL exec "xscreensaver-command -restart"
+ "Kill Screen Saver" NULL exec "xscreensaver-command -exit"
+ "Launch Screen Saver" NULL exec "xscreensaver"
+.EE
+then add
+.EX
+ "XScreenSaver" NULL menu "xscreensaver.menu"
+.EE
+to \fI~/.enlightenment/file.menu\fP to put the XScreenSaver submenu on
+your left-button root-window menu.
+
+As you see, every window manager does this stuff gratuitously differently,
+just to make your life difficult. You are in a maze of twisty menu
+configuration languages, all alike.
.SH BUGS
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
If you're running Irix 6.3, you might find that your monitor is powering down
after an hour or two even if you've told it not to. This is fixed by SGI
patches 2447 and 2537.
-.TP 8
-.B OpenGL Programs and Visuals
-Some of the graphics demos included with xscreensaver make use of the
-OpenGL (or MesaGL) 3D library, if it is available. It is possible (even
-likely) that \fIxscreensaver\fP's notion of the ``\fIbest\fP'' visual is
-not quite right for these GL programs.
-
-The odd thing about GL programs is that, unlike normal X11 programs, they
-tend to work best on a visual \fIhalf\fP as deep as the depth of the screen,
-since that way, they can do double-buffering. Try it and see, but you will
-probably find that, for these particular programs, you should specify the
-deepest visual that is half as deep as the screen. (See the discussion
-of the \fBprograms\fP resource in the \fIConfiguration\fP section, above.)
-
-For example, on a screen that supports both 24-bit TrueColor and 12-bit
-PseudoColor visuals, the 12-bit visual will probably work best (this is true
-of base-model SGI Indys: the 0x29 visual is the one you want.)
-
-Oddly, on SGI O2s (machines that have serious hardware support for GL), the
-12-bit PseudoColor visual looks awful (you get a black and white, flickery
-image.) On these machines, the visual you want turns out to be 0x31.
-However, 0x31 is but \fIone\fP of the \fIeight\fP 15-bit TrueColor visuals
-(yes, 8, and yes, 15) that the O2 X server provides. This is the only visual
-that works properly: as far as
-.BR xdpyinfo (1)
-is concerned, all of the 15-bit TrueColor visuals are identical, but some
-flicker like mad, and some have deeply weird artifacts (such as hidden
-surfaces that show through, as if depth worked backwards!)
-
-I suppose these other visuals must be tied to some arcane hardware feature...
-If anyone would care to explain it to me, that would be great.
-Your mileage, therefore, may vary dramatically.
+If you're running Irix 6.5, this bug is back. I don't know a fix.

.B MesaGL and Voodoo Cards
If you have a 3Dfx/Voodoo card, the default settings for xscreensaver will
as normal users, then the problem is that your \fI/dev/3dfx\fP file is not
configured properly. Check the Linux 3Dfx FAQ.
.TP 8
+.B Keyboard LEDs
+If \fIprocInterrupts\fP is on (which is the default on Linux systems) and
+you're using some program that toggles the state of your keyboard LEDs,
+xscreensaver won't work right: turning those LEDs on or off causes a
+keyboard interrupt, which xscreensaver will interpret as user activity.
+So if you're using such a program, set the \fIprocInterrupts\fP resource
+to False.
