.SH DESCRIPTION
The \fIxscreensaver\-demo\fP program is a graphical front-end for
setting the parameters used by the background
and
.BR xscreensaver\-command (1)
manuals.
-.SH GRAPHICS DEMOS TAB
-On the left is a list of the names of the various display modes, and
-on the right are some fields that let you edit their behavior.
+.SH DISPLAY MODES TAB
+This page contains a list of the names of the various display modes, a
+preview area, and some fields that let you configure screen saver behavior.
+.TP 4
+.B Mode
+This option menu controls the behavior of the screen saver. The options are:
+.RS 8
+.TP 8
+.B Random Screen Saver
+When blanking the screen, select a random display mode from among those
+that are enabled and applicable. This is the default.
+.TP 8
+.B Only One Screen Saver
+When blanking the screen, only ever use one particular display mode (the
+one selected in the list.)
+.TP 8
+.B Blank Screen Only
+When blanking the screen, just go black: don't run any graphics hacks.
+.TP 8
+.B Disable Screen Saver
+Don't ever blank the screen, and don't ever allow the monitor to power down.

.B Demo List
Double-clicking in the list on the left will let you try out the indicated
Clicking the mouse again will stop the demo and un-blank the screen, making
the dialog box visible again.
-Single-clicking in the list will populate the fields on the right side of
-the window.
+Single-clicking in the list will run it in the small preview pane on the
+right. (But beware: many of the display modes behave somewhat differently
+when running in full-screen mode, so the scaled-down view might not give
+an accurate impression.)
-Each name in the list has a checkbox next to it: this is a duplicate of
-the \fIEnabled\fP checkbox, and indicates (and controls) whether
-xscreensaver will use this display mode at all. If the box is not
-checked, then this demo will not be run automatically (though you can
-run it explicitly by double-clicking on its name.)
+When \fBMode\fP is set to \fBRandom Screen Saver\fP, each name in the list
+has a checkbox next to it: this controls whether this display mode is
+enabled. If it is unchecked, then that mode will not be chosen. (Though
+you can still run it explicitly by double-clicking on its name.)

.B Arrow Buttons
Beneath the list are a pair of up and down arrows. Clicking on the down
mode, just as if you had double-clicked on it. The up arrow goes the other
way. This is just a shortcut for trying out all of the display modes in turn.

-.B Program Description
-At the top will be a brief description of the program. Below that is a
-text field where you can edit the arguments to the program as xscreensaver
-will invoke it. (Note that most of these programs have their own man pages
-that describe the command-line options they take.)
-.TP 4
-.B Enabled
-The \fIEnabled\fP checkbox controls whether xscreensaver will use this
-display mode at all. This way, all the modes can remain available, but
-you can choose which ones will be automatically run.
-.TP 4
-.B Visual
-The \fIVisual\fP field is where you can select the X visual type that this
-demo will require. If you specify one (other than \fIAny\fP) then the
-program will only be run on that kind of visual. For example, you can
-specify that a particular program should only be run if color is available,
-and another should only be run in monochrome. See the discussion of the
-\fIprograms\fP parameter in the \fIConfiguration\fP section of the
-.BR xscreensaver (1)
-manual.

-This is a combo-box, so you can either select an item from the popup menu,
-or type in a specific visual's hexadecimal ID.
-.TP 4
-.B Demo
-This button runs the demo in full-screen mode so that you can try it out.
-Click the mouse to dismiss it.
-.TP 4
-.B Documentation
-Since each of the display modes is actually a separate program, they each
-may have their own manual. This opens a window viewing the man page of
-this program, if it has one.
-.SH SCREENSAVER OPTIONS TAB
-This tab lets you change various settings used by the xscreensaver daemon
-itself, rather than its sub-programs.
-.TP 4
.B Blank After
After the user has been idle this long, the \fIxscreensaver\fP daemon
will blank the screen.

+jAfter the screensaver has been running for this long, the currently
running graphics demo will be killed, and a new one started.
If this is 0, then the graphics demo will never be changed:
only one demo will run until the screensaver is deactivated by user
activity.

-.B Require Password
-Whether the screen saver should lock the screen when it activates.
-.TP 4
-.B Lock After
-If \fIRequire Password\fP is selected, this controls the length of
-the ``grace period'' between when the screensaver activates, and when the
-screen becomes locked. For example, if this is 0:05:00,
-and \fIBlank After\fP is 0:10:00, 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, \fILock After\fP 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.
+.B Lock Screen
+When this is checked, the screen will be locked when it activates.
+.TP 4
+.B Lock Screen After
+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 minutes, and \fIBlank After\fP is 10 minutes,
+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, \fILock Screen After\fP 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.
+.TP 4
+.B Preview
+This button, below the small preview window, runs the demo in full-screen
+mode so that you can try it out. This is the same thing that happens when
+you double-click an element in the list. Click the mouse to dismiss the
+full-screen preview.
+.TP 4
+.B Settings
+This button will pop up a dialog where you can configure settings specific
+to the display mode selected in the list.
+.SH ADVANCED TAB
+This tab lets you change various settings used by the xscreensaver daemon
+itself, rather than its sub-programs.

.B Grab Desktop Images
Some of the graphics hacks manipulate images. If this option is selected,

file, or the X resource database.
+.SH SETTINGS DIALOG
+When you click on the \fISettings\fP button on the \fIDisplay Modes\fP
+tab, a configuration dialog will pop up that lets you customize settings
+of the selected display mode. Each display mode has its own custom
+configuration controls on the left side.
+
+On the right side is a paragraph or two describing the display mode.
+Below that is a \fBDocumentation\fP button that will display the display
+mode's manual page, if it has one, in a new window (since each of the
+display modes is actually a separate program, they each may have their
+own manual.)
+
+The \fBAdvanced\fP button reconfigures the dialog box so that you can
+edit the display mode's command line directly, instead of using the
+graphical controls. It also lets you configure the X visual type that
+this mode will require. If you specify one (other than \fIAny\fP) then
+the program will only be run on that kind of visual. For example, you
+can specify that a particular program should only be run if color is
+available, and another should only be run in monochrome. See the
+discussion of the \fIprograms\fP parameter in the \fIConfiguration\fP
+section of the
+.BR xscreensaver (1)
+manual.
