no wonder we are not able to do the same. Looking at xset's man page it says
dpms flags...
The dpms option allows the DPMS (Energy Star) parameters to be set. 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’, ‘off’, or ‘on’. When numerical values are given, they set the inactivity period (in units of seconds) 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.
aha, a cursory look at my as well shown by hirak99 see the timeouts
