[SOLVED] Extra resolutions for games with Nvidia drivers

Question

When using the nouveau drivers, games and other such applications will allow me to select any resolution my screens (one 1920x1080, the other 1680x1050-- the latter of which is to the left of the first) will support, as well as 3600x1080, the combined total (spanning both screens). For instance, I can make something like Tux Racer 1280x800, and either windowed or fullscreen. However, with the Nvidia proprietary drivers, the only resolutions that I can select are 1920x1080, 1680x1050, and 3600x1080. This prevents me from playing windowed games in such a way that they don't cover my whole screen, or playing fullscreen games at lower resolutions for higher performance. How can I use the Nvidia drivers and the "extra" resolutions? (Ideally, all those listed in the Xinerama output below)
Xrandr outputs this:

Thanks. The first link worked, in the sense that my games now have all those resolution options, but now there's a new bug.
To future readers: a solution has been found for this bug as well, see below.
My metamodes setting now reads:
Option "metamodes" "CRT-0: nvidia-auto-select, CRT-1: nvidia-auto-select; nvidia-auto-select {ViewPortI n=1920x1080}; nvidia-auto-select {ViewPortIn=1680x1050}; [b]nvidia-auto-select {ViewPortIn=1600x1200};[/b] nvidia-auto-sele ct {ViewPortIn=1440x900}; nvidia-auto-select {ViewPortIn=1400x1050}; nvidia-auto-select {ViewPortIn=1280x1024}; nvi dia-auto-select {ViewPortIn=1280x960}; nvidia-auto-select {ViewPortIn=1280x800}; nvidia-auto-select {ViewPortIn=115 2x864}; nvidia-auto-select {ViewPortIn=1024x768}; nvidia-auto-select {ViewPortIn=832x624}; nvidia-auto-select {View PortIn=800x600}; nvidia-auto-select {ViewPortIn=700x525}; nvidia-auto-select {ViewPortIn=640x480}; nvidia-auto-sele ct {ViewPortIn=512x384}; nvidia-auto-select {ViewPortIn=400x300}; nvidia-auto-select {ViewPortIn=320x240}
Because I now have included a resolution whose height is 1200 (or so I suppose-- if I remove that part, the issue does not occur), this happens:
Xrandr output:
Screen 0: minimum 8 x 8, current 3600 x 1200, maximum 16384 x 16384
My X screen has the right length, but the wrong height! Now, my desktop seems to span the right area (3600x1080), but if I move my mouse to the bottom of that area, it pans down another 120 pixels. In that area, there's just graphical gibberish, often whatever I had on the screen last time.
If I use Xrandr to set my screens' output, it works again, butthere a solution within the Nvidia driver settings...
EDIT: It occurs to me that the setting seems to be taking the largest possible resolution for the X screen based on those metamodes.
EDIT 2: This is likely intended behavior. The proper virtual resolution (X screen resolution) may be restored by adding
Virtual 3600 1080
to the "Display" subsection under the "Screen" section.
I'll mark this as solved.
Here's my working xorg.conf, by the way. I've posted only the "Screen" section because that's all I've changed. The rest is in my first post.
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "Stereo" "0"
Option "nvidiaXineramaInfoOrder" "CRT-0"
Option "TwinViewOrientation" "CRT-1 LeftOf CRT-0"
Option "metamodes" "CRT-0: nvidia-auto-select, CRT-1: nvidia-auto-select; nvidia-auto-select {ViewPortIn=1920x1080}; nvidia-auto-select {ViewPortIn=1680x1050}; nvidia-auto-select {ViewPortIn=1600x1200}; nvidia-auto-select {ViewPortIn=1440x900}; nvidia-auto-select {ViewPortIn=1400x1050}; nvidia-auto-select {ViewPortIn=1280x1024}; nvidia-auto-select {ViewPortIn=1280x960}; nvidia-auto-select {ViewPortIn=1280x800}; nvidia-auto-select {ViewPortIn=1152x864}; nvidia-auto-select {ViewPortIn=1024x768}; nvidia-auto-select {ViewPortIn=832x624}; nvidia-auto-select {ViewPortIn=800x600}; nvidia-auto-select {ViewPortIn=700x525}; nvidia-auto-select {ViewPortIn=640x480}; nvidia-auto-select {ViewPortIn=512x384}; nvidia-auto-select {ViewPortIn=400x300}; nvidia-auto-select {ViewPortIn=320x240}"
