Comment 169 for bug 969359

** Please change the status of this bug to Confirmed

I can confirm that this is still happening in Utopic.

My story is same as Ritberg's.
After I connect via VNC to my vinagre daemon the io usage slowly (during approx 20 hours) climbs to 100% and the system proceeds to hang while excessively writing to disk. strace shows that dconf-service is writing /org/gnome/desktop/peripherals/keyboard/numlock-sate on and off all the time.

This might help to diagnose the bug:
Setting /org/gnome/desktop/peripherals/keyboard/remember-numlock-state to off immediately fixed this issue for me without any additional side effects. I recommend shipping default installations with this flag to off.
Please note that the device in question is Aspire V3-551G and the built-in keyboard does not have a num lock led.
