The option can take up to three - numerical values, or the `force' flag followed by a - DPMS state. The `force' flags forces the server to - immediately switch to the DPMS state specified. The - DPMS state can be one of `standby', `suspend', or - `off'. When numerical values are given, they set the - inactivity period before the three modes are activated. - The first value given is for the `standby' mode, the - second is for the `suspend' mode, and the third is for - the `off' mode. Setting these values implicitly - enables the DPMS features. A value of zero disables a - particular mode. - - However, note that the implementation is more than a little bogus, - in that there is code in /usr/X11R6/lib/libXdpms.a to implement all - the usual server-extension-querying utilities -- but there are no - prototypes in any header file!
