“Out-of-the-box, the Intel video bios doesn’t support a
monitor at1680x1050 resolution, which is what my Acer widescreen
monitor runs at. There is a very clever program called
915resolution that modifies the video bios to support otherwise
unavailable video modes. Here is a complete set of instructions to
make an Acer AL2223W 22″ monitor work with Fedora Linux and an
Intel 915G video chipset. I originally set this up on Fedora Core 6
but have subsequently updated this computer to Fedora 7 using
exactly the same method, so it has been tested with both of these
operating systems and works well with my setup.”
