How do I go about changing my refresh rate, from 60 to 75,
permanently? I read some suggesting changing a startup script and
using xrandr to switch while others suggested using xorg.conf, which
is not present and I do not wish to use for purist sake. Are there
more ways to change rates?

Does X detect the optimal rates (with a + sign) every time it starts
or does it use a preconfigured source?

In U11.04, I note that the Monitor Setting GUI has an option to
configure the rate. Does it use xrandr in a startup script to set it

$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024
VGA-0 connected 1280x1024+0+0
  1280x1024      60.0*+   75.0
  1280x960       60.0
  1152x864       75.0
