Hi,

The system notifications in my ubuntu are quite ugly.
(please see attached screenshot: black borders, gray background, big ugly fonts)

Another issues is they span across both monitors.
(I've marked with a red line the common border for my monitors)
This is a problem since I usually keep the second monitor off to save energy.

I have ubuntu 12.10, lightdm, gnome-no effects.
I've tried to change the themes in gnome-tweak-tool but the notifications stay the same.

How can I change the notification schema?
Also how can I force the notifications to appear only on my primary monitor?

Code:
$> gnome-session --version
gnome-session 3.6.0

$> uname -a
Linux ubuntu 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012 i686 i686 i686 GNU/Linux


Please help,
PM
