(These aren't documented in the man page) XRRGetScreenResourcesCurrent returns the current modes without also polling the hardware for changes. It's far cheaper, and should always be used unless you plan on responding to changes. And, yes, you have to check the randr version yourself. XRRQueryVersion will do that for you. > - How do I know the current mode? resource->modes[0] can't be right. Query the associated CRTC; the current mode is identified in there. -- keith.pack...@intel.com
