How to compose a mode line for your card/monitor combination under
XFree86. The XFree86 distribution now includes good
facilities for configuring most standard combinations; this document
is mainly useful if you are tuning a custom mode line for a
high-performance monitor or very unusual hardware. It may also help
you in using xvidtune to tweak a standard mode that is not quite right
