I've been trying - without any success - to create a "virtual" display device configured for 16:9 ratio resolution..
I'm already past setting a kernel option (forgot what it was) for xorg to even start up without a physical display device connected to the display port.
Below is my xorg.conf. What i would basically like to achieve is a 16:9 resolution such as 1440x900 instead of all the 4:3 resolutions this configuration apparently provides ( despite the modes and metamodes defined below, i only get to choose 4:3 resolutions like 1024x768 )
Thanks much! Andras
ps: again, i have no physical display device.

Tip: blocks like that those last two comments are best edited into your original question, usually headed with update or added. I've got nothing much to offer beyond that you should be looking for the terms "virtual frame buffer" and "headless server" and "unbuntu or debian". It is hard for a driver to attach to hardware that doesn't exist. – msw – 2010-07-04T13:51:51.400
