I am attempting to install and use fbgrab, but it requires /dev/fb0 to exist. How can I create this file?
My computer specs: Dell Studio 1555, ATI Radeon 4500, proprietary graphics driver
This may be down to X not using a framebuffer system, however the application you are trying to use is to take screenshots? Ubuntu already has a screnshot taking application, which you can launch from Applications > Accessories > Take Screenshot
