"...try an output different from surface."
I did try all other options (overlay, opengl, openglnb) but it doesn't seem to change anything - I still end up with a small content area surrounded by large black borders in fullscreen mode. DOSBox shows NO error messages of any kind (e.g. "falling back to surface mode" or some such) when started. And when I type "output" at the prompt I always get the right answer.
I'm on Ubuntu 13.04, using their NVIDIA 313.30 drivers on a GTX 260 card. The problem appeared when I finally replaced my trusty old CRT with a flat panel display and got rid of all my special X Modelines. I used to run DOSBox at the native DOS resolutions and refresh rates, now I'd like it to work at (and make full use of) 1280x1024x60Hz.
My dosbox.conf and xorg.conf are attached.
I'd be thankful for any ideas...
