[arch-general] Script to check monitor blank state

Hello everyone, i would like to write a little script, that suspends my computer if a few circumstances are met. One should be, that my screen should be blanked. I already did a google search on this, but i only found howtos of getting it to work / disable it. It looks like xset q does not print the actual state. Maybe there is a hook for screen blanking? I know this is not a arch specific question, but maybe someone can help me. Markus
