## 19. Screensaving

`setterm -blank` nn will tell the console driver to blank the screen after nn minutes of inactivity. (With nn = 0, screensaving is turned off. In some old kernels this first took effect after the next keyboard interrupt.)

The `s` option of xset(1) will set the X screensaving parameters: `xset s off` turns off the screensaver, `xset s 10` blanks the screen after 10 minutes.

The video hardware powersaving modes can be enabled/disabled using the `setvesablank` program given in the starting comment of `/usr/src/linux/drivers/char/vesa_blank.c`.
