No it is not a bug. ddc probe is very dependent on video card/monitor
combinantion. If resolutions is not detected we need to ask the user for
sane defaults.

When we guess frequency ranges from resolutions we need to keep them at
the minimum, since we don't know if:

a) the user did a mistake selecting the resolution
b) the monitor is capable of doing what the video card can

in this way X will almost always come up without burning your hardware and
your eyes.

dpkg-reconfigure xserver-xfree86 is a better option than editing the
config manually.

Please do, but there is not much we can really do about it.

Thanks for your report!

<fajita> Whatever the problem, step one is always to look in the error log.
<user> fajita: step two
<fajita> When in danger or in doubt, step two is to scream and shout.
