That does indeed matter! Thanks. Not only did the usb rh poll function disappear, but I now also get 99% C3 state with an average residency of 100ms (or 200ms if X is running). I'm wondering why 'auto' isn't default... That leaves me with: - fbcon_add_cursor_timer which is called only when X is not running. That creates an interesting situation where with X running I get less wakeups per second than without X (the fbcon function fires five times per second, and X only adds ~2 wakeups/s). - xfsbufd is still there, accounting for two wakeups per second. - clocksource_register sometimes appears after a fresh boot, and disappears later, accounting for two wakeups/s. It wasn't listed before because I haven't rebooted the laptop, and after a few minutes that function disappears (or after I start something, I'm not sure). I'll look into increasing the fbcon timer and getting rid of the clocksource function to see if that improves my power consumption. Thanks so far. tom _______________________________________________ Discuss mailing list [email protected] http://mail.lesswatts.org/mailman/listinfo/discuss
