Before switching off the screen, the screen saver dims the screen a bit. For me, the time of having the screen dimmed is not long enough, so I often have to retype my password. I'd like to have a longer dim-time. How can I get this?
(I am not asking for How do you change the amount of time before the screen dims?)
It seems this value (10 seconds) is hard coded in the code. There is no way to change it unless you re-compile the power management code. It's managed by gnome-screensaver.

You can however download gnome-screensaver source package from Launchpad: https://launchpad.net/ubuntu/precise/+source/gnome-screensaver. The source code of fade out effect can be found in gs-fade.c and gs-fade.h files from src directory:
To install, follow this post: Installing applications from source
