- The _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bd_\be_\bm_\bo program is a graphical front-end for
- setting the parameters used by the background x\bxs\bsc\bcr\bre\bee\ben\bn-\b-
- s\bsa\bav\bve\ber\br(1) daemon. It is essentially two things: a tool for
- editing the _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file; and a tool for demoing
- the various graphics hacks that the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br daemon
- will launch.
-
- The main dialog box contains a scrolling list, a text
- field, and a number of buttons.
-
- Double-clicking on one of the programs in the list will
- run it. The screen will go black, and the program will
- run in full-screen mode, just as it would if the _\bx_\bs_\bc_\br_\be_\be_\bn_\b-
- _\bs_\ba_\bv_\be_\br daemon had launched it. 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 place the indicated pro-
- gram and its args in the text field to be edited. Edit
- the arguments and hit return to run the program with the
- parameters you have specified. This will also save your
- changes to your _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file: so any changes you
- make in this way are persistent.
-
- If one of the lines in the scrolling list begins with the
- character "-", then that means that the program is dis-
- abled: _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br will not select it to be run (though
- you can still try it out by clicking on it.) Rather than
- just deleting the programs you don't want to run, you
- might want to disable them in this way instead, so that
- you can more easily change your mind later.
-
- If the line begins with the name of a visual, followed by
- a colon, then that 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 discus-
- sion of the _\bp_\br_\bo_\bg_\br_\ba_\bm_\bs parameter in the _\bC_\bo_\bn_\bf_\bi_\bg_\bu_\br_\ba_\bt_\bi_\bo_\bn sec-
- tion of the x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) manual.
-
- The buttons are:
-
- R\bRu\bun\bn N\bNe\bex\bxt\bt
- Clicking this button will run the next program in
- the list after the currently-selected one, and

- This pops up a second dialog box, in which you
- have the option to interactively change most of
- the screensaver's operational parameters, such as
- its timeouts, and whether it should lock the
- screen. When you click OK, your chosen settings
- will take effect immediately, and will also be
- saved to the _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file in your home
- directory, so that the settings will persist next
- time.
-
- Q\bQu\bui\bit\bt Exits the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bd_\be_\bm_\bo program. The back-
- ground _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br daemon will continue running
- as before.
-
- The Preferences dialog box lets you change the following
- settings.
-
- (There are more settings available, but these are the most
- commonly used ones; see the manual for x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) for
- other parameters that can be set by editing the
- _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file, or the X resource database.)

- After the user has been idle this long, the
- _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br daemon will blank the screen.
-
- C\bCy\byc\bcl\ble\be T\bTi\bim\bme\beo\bou\but\bt
- After 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.

- Whether to print lots of debugging information.
-
- I\bIn\bns\bst\bta\bal\bll\bl C\bCo\bol\blo\bor\brm\bma\bap\bp
- Whether to install a private colormap while the
- screensaver is active, so that the graphics hacks
- can get as many colors as possible. (This only
- applies when the screen's default visual is being
- used, since non-default visuals get their own col-
- ormaps automatically.) This can also be overrid-
- den on a per-demo basis.

- If selected, then when the screensaver activates,
- the current contents of the screen will fade to
- black instead of simply winking out. This only
- works on displays with writable colormaps, that
- is, if the screen's default visual is a Pseudo-
- Color visual. A fade will also be done when
- switching graphics hacks (when the _\bC_\by_\bc_\bl_\be _\bT_\bi_\bm_\be_\bo_\bu_\bt
- expires.)
-
- U\bUn\bnf\bfa\bad\bde\be C\bCo\bol\blo\bor\brm\bma\bap\bp
- The complement to _\bF_\ba_\bd_\be _\bC_\bo_\bl_\bo_\br_\bm_\ba_\bp: if selected, then
- when the screensaver deactivates, the original
- contents of the screen will fade in from black
- instead of appearing immediately. This only works
- on displays with writable colormaps, and when _\bF_\ba_\bd_\be
- _\bC_\bo_\bl_\bo_\br_\bm_\ba_\bp is also selected.
-
- F\bFa\bad\bde\be D\bDu\bur\bra\bat\bti\bio\bon\bn
- When fading or unfading are selected, this con-
- trols how long the fade will take.
-
- F\bFa\bad\bde\be T\bTi\bic\bck\bks\bs
- This controls 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 number of seconds, if
- your server isn't fast enough to keep up.
-
- R\bRe\beq\bqu\bui\bir\bre\be P\bPa\bas\bss\bsw\bwo\bor\brd\bd
- Whether the screen saver should lock the screen
- when it activates.
-
- L\bLo\boc\bck\bk T\bTi\bim\bme\beo\bou\but\bt
- If _\bR_\be_\bq_\bu_\bi_\br_\be _\bP_\ba_\bs_\bs_\bw_\bo_\br_\bd 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
- _\bS_\ba_\bv_\be_\br _\bT_\bi_\bm_\be_\bo_\bu_\bt is 0:10:00, then after 10 minutes,
- the screen would blank. If there was user activ-
- ity 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, _\bL_\bo_\bc_\bk
- _\bT_\bi_\bm_\be_\bo_\bu_\bt 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.
-
- P\bPa\bas\bss\bsw\bwo\bor\brd\bd T\bTi\bim\bme\beo\bou\but\bt
- When the screensaver is prompting for a password,
- the prompt dialog box will stay on the screen for
- this long before giving up, and reverting to
- screen-saving mode.

- The X display to use. The _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bd_\be_\bm_\bo pro-
- gram will open its window on that display, and

- _\bs_\ba_\bv_\be_\br_\b-_\bd_\be_\bm_\bo processes be running on the same machine, or at

- _\bs_\ba_\bv_\be_\br file, it's important that the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br see that

- _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br files, things will malfunction.
