This is a problem which has been bothering me for a while and so far I’ve had little success solving it. I enjoy playing older games, and my monitor is widescreen. Most older games, when run fullscreen, appear distorted. Under Windows it’s a simple matter to correct this (that is, to letterbox smaller resolutions with black bands on the sides) in the Nvidia settings panel, but no such option exists under nvidia-settings.
Doing some digging I was able to find this documentation, which seems to suggest that “metamodes” can be used to do this. However, the syntax confuses me. How can I center a game with, say, 1024x768 resolution, on my 1680x1040 desktop, without distortion?
The machine is running a GeForce GTX 650, 64-bit AMD CPU, and the OS is Debian.
Thanks for any suggestions!
