If using the command manually in a shell you may need to prefix it with sleep 1; for it to work correctly, for example sleep 1; xset dpms force off xset dpms 0 0 0 , which sets all the DPMS timeouts to zero, could be a better way to "disable" DPMS, since the effect of -dpms would be reverted when, for example, turning off the screen with xset dpms force off.

Console blanking is disabled by default. See the kernel documentation for details. This is most often implemented by shutting off the horizontal sync signal to the monitor. A value of zero disables this mode. Suspend mode is the middle level of power savings, resulting in a slightly longer recovery upon detection of activity. Suspend mode is most often implemented by pulsing the horizontal sync signal, and removing the vertical sync signal.

Off mode is the deepest level of power management, resulting in the greatest power savings and the longest recovery time. Off mode is most often implemented by removing both the horizontal and vertical signals. The values of successive power levels must be greater than or equal to the value of the previous non-zero level. A BadValue error is generated if an illegal combination is detected.

This request enables the DPMS characteristics of the server, using the server's currently stored timeouts. If DPMS is already enabled, no change is effected.
