Default Screen does not sync when un-plugging and re-plugging

Hi all,

I have a Gentoo system with a Quadro 4000 card and two monitors connected on DisplayPorts.
When I un-plug a monitor from the DisplayPort outlet and re-plug it, my monitor never syncs back.
I need to restart the XServer for the monitor to sync again.

I compiled the nv-control-dpy tool to get more information.
Here is the output of the command nv-control-dpy --probe-dpys when one of my monitor is un-plugged:
Quote:
Using NV-CONTROL extension 1.25 on :0
Connected Display Devices:
DFP-1 (0x00020000): DELL U2410
DFP-2 (0x00040000): DELL U2410

Display Device Probed Information:

number of GPUs: 1
display devices on GPU-0 (Quadro 4000):
DFP-1 (0x00020000): DELL U2410
DFP-2 (0x00040000): DELL U2410
As you can see, the card still detects both monitors even when only one is connected.
Is there any specific configuration in the Kernel or xorg.conf that needs to be done in order to get the monitor sync correctly when I plug it back?

Thanks a lot.
Franck
