Slightly offtopic, but:
Is that true? What is affected by screen refresh rate? Only speed of graphics
output, right? Because the workload on the graphics card may be lower? (Talking
on non-onboard graphics, of course).
Is there a way of setting screen refresh explicitely in XF86Config for different
modes that? Or do I have to calculate modelines for that?
(btw. a good tool is found at
Can I have different modelines for the same resolution? E.g. one with 90 Hz, one
with 60? How do I activate these and switch between these? Normally I use xv
output (ATI XPert at Work) and that doesn't change X-mode, but hardware-scales the
Some of this (with answers ;-) might be included in the DOCS,
