Bug#658786: Hello says `goodbye'

[Patrik Dufresne]

Package:gnome-settings-daemon

Version: 3.2.2-2

My computer is a ThinkPad T510 and I usually use the Fn+F7 keys to
change the monitor configuration. With Debian, using these keys invoke
the rotation using xrandr. Since I'm using Nvidia binary driver, the
Fn+F7 keys doesn't work as expected. When I press it, I get an error
message.

Here the step to reproduce.
1. Connect an external display to the VGA port
2. Press Fn+F7
3. The following error message is displayed :
Could not switch the monitor configuration
could not set the configuration for CRTC 354


I suggest to detect whether xrandr is working or not. In case Nvidia
binary driver is used, pressing Fn+F7 should do nothing. Of course,
the best would be to invoke a utility like 'disper'  to change the
monitor configuration.

I am using Debian GNU/Linux testing, kernel 3.1.0-1-amd64.
