but my monitor (BenQ GL2450HM) disagrees; the real mode is 1680x1050. And I side with the monitor here. Anyone seen this before?
When I check /var/log/Xorg.0.log, it looks like my monitor is correctly detected:

But there are many nvidia-drivers (-304, -173, -96, -71) in ports. How do I know which one I need?

The -173, -96 and -71 versions are those after which NVIDIA dropped support for certain older cards.

The 8 series is still supported by the latest driver, at least the 8600m GT in my laptop is.
 
FWIW, nvidia-driver (currently using 304.64) works correctly. I would like to get the nv driver working correctly too.

Is there a specific reason why you would like to use an inferior driver (other than because it's open source)? It doesn't even have 3D acceleration.
volatilevoid said:
(suggested by me earlier) If you want to use an open source driver, I'd suggest looking into x11-drivers/xf86-video-nouveau. Unfortunately, the FreeBSD version is a bit out of date and has no 3D acceleration either. For 2D acceleration, you need a patch, see the pkg-message.
Click to expand...
Never mind my suggestion to the xf86-video-nouveau driver. Didn't see the IGNORE line in the Makefile:
Code: 
# also doesn't work with mesa (libGL) version higher then 7.4.x
IGNORE= Not supported, missing kernel support. use the nvidia driver.
So, bottom line is: stick to the proprietary driver.

Open source is a very big reason to use stuff, IMHO. If the nv driver could be coerced into giving the correct resolution, the driver itself is good enough; I don't need 3D acceleration on this machine. Other advantages of the nv driver compared to the Nvidia driver: it doesn't need the linux kernel module or linux_base, it works without the need for a kernel module (nvidia.ko).

I will if I must, but I prefer not to. Get it?
 
With the correct build options set in the port, the binary Nvidia driver can be built without the Linux compat requirement (I think it is strange that the default is to depend on Linux to be honest).
 
There is one truly harrowing thing though about the NVidia driver. It clobbers libGL.so.1 and libglx.so, meaning that if I use a liveCD on machines that have other video cards in them, things are seriously broken.

Whose dumb idea was it to clobber existing files rather than having the driver and executables call what they want directly? I've read that others have tried various ideas such as libmap.conf or setting LD_LIBRARY_PATH, but so far nothing has come of any of these suggestions. As a result, I'm stuck with the nv driver which doesn't support many newer NVidia cards, and provides 800x600 resolution VESA if I'm lucky. Looks pretty bad on a wide screen.

What would really be neat would be some kind of script which could detect the presence of an NVidia card in the machine and set up the appropriate links before X starts up.
