alphabetize these?

 
 int main(int argc, char *argv[]) {
   power_manager::XIdle idle;
-  idle.Init();
+  Display* display = XOpenDisplay(NULL);

it'd be good to CHECK(display) here; that's what X apps usually do (to catch the
common case where someone tries to run it when no X server is present or when
$DISPLAY is set incorrectly)

+  bool init = idle.Init(display);
+  CHECK(init);
   idle.AddIdleTimeout(2000);
   idle.AddIdleTimeout(5000);
   bool is_idle;
   int64 idle_time;
   while (idle.Monitor(&is_idle, &idle_time)) {
     if (is_idle)
       printf("User has been idle for %" PRIi64 " milliseconds\n", idle_time);
     else
       printf("User is active\n");
   }
+  XCloseDisplay(display);
   return 0;
 }
