- The _s_s_a_v_e_r customization panel allows the user to toggle the screen saver
- on or off, demo the available screen savers, and choose a new screen
- saver. In IRIX 6.2 and later releases, it also lets the user configure
- the power saver option available on some systems.
-
- This customization panel does not control the power saver settings that
- take effect when no one is logged into the console. To change these,
- edit (as root) the /_u_s_r/_l_i_b/_X_1_1/_x_d_m/_X_l_o_g_i_n file. See the _x_d_m(_1)
- reference page for more information.
-
- The _s_s_a_v_e_r program can be accessed from the toolchest (Desktop >
- Customize > Screen Saver) or at a Unix command line. Like most other
- customization panels, the _s_s_a_v_e_r panel has the ``runonce'' feature,
- meaning only one instance of the application will run at one time.
- Attempting to launch the application a second time will have the effect
- of deiconifying the application window or popping it to the top on the
- current desk.
-
- In IRIX 6.3 and later releases, the Atlantis demo program is recognized
- as a screensaver. To make it available in this panel, install the
- ddddeeeemmmmoooossss....sssswwww....aaaattttllllaaaannnnttttiiiissss subsystem from the IRIX distribution CD.
-
- The user can set the _s_c_r_e_e_n _s_a_v_e_r _t_i_m_e_o_u_t, the length of time for which
- the display should be inactive before the screen saver launches. The
- user can also set whether to lock the screen for particular screen
- savers. (See the xlock(1) man page for more information about locking
- the X server.) The Random setting will launch at random one of the other
- available screen savers after the designated screen saver timeout.
-
- In IRIX 6.2 and later releases, the _s_s_a_v_e_r panel also allows the power
- saver option to be used on appropriate monitors, and with any screen
- saver. In IRIX 5.3, the power saver is available only with the Blank
- screen saver.
-
- The power saver option essentially turns off the monitor when the user is
- away from the machine for a long time, so the monitor consumes much less
- power. The power saver blanks the screen and turns off video
- synchronization, so the monitor consumes 3-4 watts of electricity versus
- its normal 100 or so watts.
-
- On monitors that support the power saver option, the user can use the
- ssaver panel to set the _p_o_w_e_r _s_a_v_e_r _t_i_m_e_o_u_t, the length of time for which
- the display should be inactive _a_f_t_e_r the screen saver has launched before
- the power saver launches. The user can also toggle the power saver
- option on or off. If the monitor does not support the power saver

-
- option, the power saver toggle and slider will be insensitive and will
- appear grayed out.
-
- Because the power saver essentially turns off the monitor, coming out of
- power-save mode can take several seconds as the monitor warms up. Thus,
- the power saver launches some time after the screen saver has launched,
- and the power saver slider on the ssaver panel has a higher maximum value
- than the screen saver slider.
-
- Users can check the monitor type with
-
- ////uuuussssrrrr////ggggffffxxxx////ggggffffxxxxiiiinnnnffffoooo
-
- Monitors that support the power saver option include
-
- O2
- Indy/Indigo2 XL (NG1) with monitor id 1, 2 or 130 (flat panel)
- Indy/Indigo2 XZ with flat panel
-
- In IRIX 5.3 and later releases, the Blank screen saver supports not only
- the power saver option but also another hardware option called _s_c_r_e_e_n
- _b_l_a_n_k_i_n_g, a video back-end implementation that does not affect the
- framebuffer unless the saver is locked. With locking turned off, the
- Blank saver causes color information to no longer be driven to the
- monitor, but the monitor is still synchronized. With locking turned on,
- however, the Blank saver causes black to be painted to the screen (xlock
- simulates blank by clearing the framebuffer to 0, thus requiring Expose
- events when coming out of screen saving).
-
- When no one is logged into the console of a system, the default screen
- saving options take effect. In IRIX 5.3, the X display manager (xdm)
- uses the Blank screen saver as the default, and the power saver option
- kicks in after 20 minutes of screen saver operation. In IRIX 6.2, the
- xdm default is also the Blank screen saver, but the power saver option is
- off by default; in IRIX 6.5, the xdm power saver option is on by default.
- This can be changed by editing /_u_s_r/_l_i_b/_X_1_1/_x_d_m/_X_l_o_g_i_n.

- The _s_s_a_v_e_r panel takes the user's settings and changes them into _x_s_e_t
- commands. (See the xset(1) man page for more information about how the
- screen saver is set.) These commands are written to $_H_O_M_E/._d_e_s_k_t_o_p-
- <_h_o_s_t_n_a_m_e>/_p_a_n_e_l_s_e_s_s_i_o_n (where <_h_o_s_t_n_a_m_e> is the name of the machine) and
- are executed by /_u_s_r/_l_i_b/_X_1_1/_x_d_m/_X_s_e_s_s_i_o_n._d_t at the start of the user's

- session.
-
- In IRIX 6.2 and later releases, the X server supports the power saver
- option by interpreting the _s_c_r_e_e_n _s_a_v_e_r _i_n_t_e_r_v_a_l setting as the power
- saver timeout. See the XSetScreenSaver(3X11) or the xset(1) man pages
- for more information about the screen saver timeout (also called _l_e_n_g_t_h)
- and about the screen saver interval (also called _p_e_r_i_o_d).
-
- The xdm default screen saver and power saver options can be changed by
- editing the file /_u_s_r/_l_i_b/_X_1_1/_x_d_m/_X_l_o_g_i_n.
