Default vsync doesn't work, ever

Hi,

I'm using a notebook with an external display and (currently) the 302.11 beta drivers. Vsync never worked properly for me, not with this monitor, not with the one I had before, not with older drivers. There's always a screen region where bad, very noticeable tearing happens, no matter if it's in Firefox or a game. I'm actually quite convinced that it's on but not in sync with the display for some reason.

I've messed with TwinView on and off, doesn't help. Forced X to only recognize the external display, no dice. My current relevant configuration:

I set
Code:
export __GL_SYNC_TO_VBLANK=1 
export __GL_SYNC_DISPLAY_DEVICE="DFP-1"
in my ~/.bashrc

Made an nvidia file in /etc/X11/xorg.conf.d/
Code:
Section "Device"
	Identifier "nvidia"
	Driver "nvidia"
	#Option "DynamicTwinView" "true"
	Option "NoLogo" "true"
	Option "DPMS" "1"
	Option "OnDemandVBlankInterrupts" "1"
	#Option "ConnectedMonitor" "DFP-1"
	Option "TripleBuffer" "true"
EndSection
Anybody got an idea what's causing this? The graphics cards is a GeForce GTX 260M, the external monitor is an Eizo FS2331.
