Bug Description
With recent (post 9 march) Jaunty updates nvidia restricted drivers do not accomplish to "On Demand Interrupts" enabled any more.
This results in increased power consumption and reduced battery life.
Despite stating in Xorg.0.log
(**) NVIDIA(0): Option "OnDemandVBlank
Powertop reports: 15.2% ( 49.5) <interrupt> : nvidia
with nvidia interrupts ranging from 45 to 60.
Since powertop reports video card interrupts along with USB host controller I have previously removed uhci_hcd module from kernel.
Installed packages are:
ii nvidia-
ii nvidia-glx-180 180.37-0ubuntu1
Linux 2.6.28-9-generic #31-Ubuntu SMP Wed Mar 11 15:43:58 UTC 2009 i686 GNU/Linux
