See http://qsynaptics.sourceforge.net/ I took a stab at rewriting syndaemon to catch X events and sleep otherwise, but was unable to figure out how to get events when a) the app is not a window, and b) events go to windows. Given that I know nothing about really writing such an app, it was an interesting couple-hour exercise, but ultimately fruitless. Someone who knows more about X could probably recreate my worthless attempt in 5 minutes, and may even know enough to do it right. -- Matt Domsch Linux Technology Strategist, Dell Office of the CTO linux.dell.com & www.dell.com/linux -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
