You do. You can turn it off and on via the hardware switch on it, and |
| 19 |
you can disable the kernel's turning it off via software controls. |
| 20 |
|
| 21 |
"man setterm" |
| 22 |
|
| 23 |
You have the ability to explicitly control display powersave behaviors |
| 24 |
using the -powersave and -powerdown options. |
| 25 |
|
| 26 |
If you're in X, you have xset. |
| 27 |
|
| 28 |
"xset -dpms" turns Energy Star features off. |
| 29 |
"xset +dpms" turns them on. |
| 30 |
"xset dpms force off" turns your display off. |
| 31 |
"xset dpms force on" turns your display on. |
| 32 |
|
| 33 |
Run 'xset' in an xterm to see all the options you have available there. |
| 34 |
|
| 35 |
If you're running xscreensaver, you can control its use of DPMS in the |
| 36 |
configuration window offered by the "xscreensaver-demo" program. GNOME |
| 37 |
and KDE also provide similar knobs. |
