Problems I am experiencing:

Battery Icon not showing up unity bar (top right corner).

Volume Up/Down/Mute not working.

Bluetooth hot keys described above also not working.Brightness up/down keys on this keyboard no longer working (apple wireless keyboard)

Laptop no longer suspends when lid is shut. I have to go to 'power' button on top right corner and click on 'Suspend'

All was working flawlessly until I did the following:

I have recently upgraded to Nvidia propriety driver version 319 {version recommended}.

Installed Xscreensaver and then removed it and went back to default screensaver.

Done a system update (1st since installing) and now currently running: Linux 3.8.0-32-generic #47~precise1-Ubuntu SMP Wed Oct 2 16:19:35 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux NOTE: Base system was ubuntu 12.04.3 installed from ISO however lsb_release reports "No LSB modules are available" 4.installed psensor.

I have check power setting (via Settings) and power setting via dconf-editor and set to recommended settings as described in posts detailing solution to this problem. - I have disabled 1) Nvdia settings at startup and 2) psensor at startup but this does not help.

I am using an HP DV7 with 2GB Nvidia card. Not using any fancy graphics features.

Recommendations?

Thanks.
