Default Re: Notebook & GeForce 8400M G

The problem here is that the EDID in your DFP caps the VRefresh range at 60Hz, even though the only defined native mode requires a 61Hz refresh rate:

(--) NVIDIA(0): Valid VRefresh Range : 0 Hz - 60 Hz
(--) NVIDIA(0): EDID maximum pixel clock : 130.0 MHz
(--) NVIDIA(0):
(--) NVIDIA(0): Detailed Timings:
(--) NVIDIA(0): 1680 x 1050 @ 61 Hz
(--) NVIDIA(0): Pixel Clock : 121.40 MHz
(--) NVIDIA(0): HRes, HSyncStart : 1680, 1728
(--) NVIDIA(0): HSyncEnd, HTotal : 1760, 1840
(--) NVIDIA(0): VRes, VSyncStart : 1050, 1052
(--) NVIDIA(0): VSyncEnd, VTotal : 1058, 1080
(--) NVIDIA(0): H/V Polarity : -/-

Try adding the following to the Device section of xorg.conf:
Option "ModeValidation" "NoVertRefreshCheck"
