The hardcoded standard mode lines are VESA standards, to which monitors
and cards are supposed to adhere. Most, these days, do. When the server
starts, it looks for information in the config file, then uses DDC and
VBE probes to find out about the capabilities of the card and monitor.
If it can't get any information from the monitor, it uses the standard
mode lines and refresh rates from VESA that are hardcoded into the
server.
