+ The _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bc_\bo_\bm_\bm_\ba_\bn_\bd program controls a running
+ _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br process by sending it client-messages.
+
+ x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) has a client-server model: the xscreen-
+ saver process is a daemon that runs in the background; it
+ is controlled by other foreground programs such as
+ _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bc_\bo_\bm_\bm_\ba_\bn_\bd and x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-d\bde\bem\bmo\bo(1).
+
+ This program, _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bc_\bo_\bm_\bm_\ba_\bn_\bd, is a command-line-ori-
+ ented tool; the x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-d\bde\bem\bmo\bo(1). program is a graph-
+ ical tool.

+ _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bc_\bo_\bm_\bm_\ba_\bn_\bd accepts the following command-line
+ options:
+
+ -\b-h\bhe\bel\blp\bp Prints a brief summary of command-line options.
+
+ -\b-d\bde\bem\bmo\bo This just launches the x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-d\bde\bem\bmo\bo(1) pro-
+ gram, in which one can experiment with the various
+ graphics hacks available, and edit parameters.
+
+ -\b-d\bde\bem\bmo\bo _\bn_\bu_\bm_\bb_\be_\br
+ When the _\b-_\bd_\be_\bm_\bo option is followed by an integer,
+ it instructs the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br daemon to run that
+ hack, and wait for the user to click the mouse
+ before deactivating (i.e., mouse motion does not
+ deactivate.) This is the mechanism by which
+ x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-d\bde\bem\bmo\bo(1) communicates with the
+ x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) daemon. (The first hack in the
+ list is numbered 1, not 0.)
+
+ -\b-p\bpr\bre\bef\bfs\bs Like the no-argument form of _\b-_\bd_\be_\bm_\bo, but brings up
+ that program's Preferences panel by default.
+
+ -\b-a\bac\bct\bti\biv\bva\bat\bte\be
+ Tell xscreensaver to turn on immediately (that is,
+ blank the screen, as if the user had been idle for
+ long enough.) The screensaver will deactivate as
+ soon as there is any user activity, as usual.
+
+ It is useful to run this from a menu; you may wish

+
+ to run it as
+
+ sleep 5 ; xscreensaver-command -activate
+
+ to be sure that you have time to take your hand
+ off the mouse before the screensaver comes on.
+ (Because if you jiggle the mouse, xscreensaver
+ will notice, and deactivate.)
+
+ -\b-d\bde\bea\bac\bct\bti\biv\bva\bat\bte\be
+ If the screensaver is active (the screen is
+ blanked), this command will deactivate it just as
+ if there had been keyboard or mouse activity. If
+ locking is enabled, then the screensaver will
+ prompt for a password as usual.
+
+ -\b-c\bcy\byc\bcl\ble\be If the screensaver is active (the screen is
+ blanked), then stop the current graphics demo and
+ run a new one (chosen randomly.)
+
+ -\b-n\bne\bex\bxt\bt This is like either _\b-_\ba_\bc_\bt_\bi_\bv_\ba_\bt_\be or _\b-_\bc_\by_\bc_\bl_\be, depending
+ on which is more appropriate, except that the
+ graphics hack that will be run is the next one in
+ the list, instead of a randomly-chosen one. In
+ other words, repeatedly executing -next will cause
+ the xscreensaver process to invoke each graphics
+ demo sequentially. (Though using the _\b-_\bd_\be_\bm_\bo option
+ is probably an easier way to accomplish that.)
+
+ -\b-p\bpr\bre\bev\bv This is like _\b-_\bn_\be_\bx_\bt, but cycles in the other direc-
+ tion.
+
+ -\b-s\bse\bel\ble\bec\bct\bt _\bn_\bu_\bm_\bb_\be_\br
+ Like _\b-_\ba_\bc_\bt_\bi_\bv_\ba_\bt_\be, but runs the _\bNth element in the
+ list of hacks. By knowing what is in the _\bp_\br_\bo_\bg_\br_\ba_\bm_\bs
+ list, and in what order, you can use this to acti-
+ vate the screensaver with a particular graphics
+ demo. (The first element in the list is numbered
+ 1, not 0.)
+
+ -\b-e\bex\bxi\bit\bt Causes the xscreensaver process to exit grace-
+ fully. This is roughly the same as killing the
+ process with k\bki\bil\bll\bl(1), but it is easier, since you
+ don't need to first figure out the pid.
+
+ W\bWa\bar\brn\bni\bin\bng\bg:\b: never use _\bk_\bi_\bl_\bl _\b-_\b9 with _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br while
+ the screensaver is active. If you are using a
+ virtual root window manager, that can leave things
+ in an inconsistent state, and you may need to
+ restart your window manager to repair the damage.
+
+ -\b-l\blo\boc\bck\bk Tells the running xscreensaver process to lock the
+ screen immediately. This is like _\b-_\ba_\bc_\bt_\bi_\bv_\ba_\bt_\be, but
+ forces locking as well, even if locking is not the

+ default (that is, even if xscreensaver's _\bl_\bo_\bc_\bk
+ resource is false, and even if the _\bl_\bo_\bc_\bk_\bT_\bi_\bm_\be_\bo_\bu_\bt
+ resource is non-zero.)
+
+ Note that locking doesn't work unless the _\bx_\bs_\bc_\br_\be_\be_\bn_\b-
+ _\bs_\ba_\bv_\be_\br process is running as you. See x\bxs\bsc\bcr\bre\bee\ben\bn-\b-
+ s\bsa\bav\bve\ber\br(1) for details.
+
+ -\b-t\bth\bhr\bro\bot\btt\btl\ble\be
+ Temporarily switch to ``blank screen'' mode, and
+ don't run any display modes at all, until the
+ screensaver is next de-activated. This is useful
+ if you're using a machine remotely, and you find
+ that some display modes are using too much CPU.
+
+ (If you want to do this _\bp_\be_\br_\bm_\ba_\bn_\be_\bn_\bt_\bl_\by, that is, you
+ want the screen saver to only blank the screen and
+ not run demos at all, then set the _\bp_\br_\bo_\bg_\br_\ba_\bm_\bs
+ resource to an empty list: See x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1)
+ for details.)
+
+ -\b-u\bun\bnt\bth\bhr\bro\bot\btt\btl\ble\be
+ Turn `-throttle' mode off and resume normal behav-
+ ior.
+
+ -\b-v\bve\ber\brs\bsi\bio\bon\bn
+ Prints the version of xscreensaver that is cur-
+ rently running on the display: that is, the actual
+ version number of the running xscreensaver back-
+ ground process, rather than the version number of
+ xscreensaver-command. (To see the version number
+ of _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bc_\bo_\bm_\bm_\ba_\bn_\bd itself, use the _\b-_\bh_\be_\bl_\bp
+ option.)
+
+ -\b-t\bti\bim\bme\be Prints the time at which the screensaver last
+ activated or deactivated (roughly, how long the
+ user has been idle or non-idle: but not quite,
+ since it only tells you when the screen became
+ blanked or un-blanked.)
+
+ -\b-r\bre\bes\bst\bta\bar\brt\bt
+ Causes the screensaver process to exit and then
+ restart with the same command line arguments as
+ last time. Do this after you've changed the
+ resource database, to cause xscreensaver to notice
+ the changes.
+
+ W\bWa\bar\brn\bni\bin\bng\bg:\b: if you have a _\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file, this
+ might not do what you expect. You're probably
+ better off killing the existing xscreensaver (with
+ _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bc_\bo_\bm_\bm_\ba_\bn_\bd _\b-_\be_\bx_\bi_\bt) and then launching it
+ again.
+
+ The important point is, you need to make sure that

+ nostic message will be printed to stderr, and _\bx_\bs_\bc_\br_\be_\be_\bn_\b-
