Thanks for the examples of xrandr's use, although in this case the solution
needed should not require a new user to immediately mess with the system at
I am hoping for a solution that is completely independent of MS Windows.
Is ddcprobe's EDID probing likely to improve in the near future? My VIA
motherboard seems to support i2c and ViewSonic has e-mailed me their EDID
output for my ViewSonic model VE710b monitor, but all I get is "edidfail" from
ddcprobe. I assume this happens to a lot of folks that are trying Ubuntu on
moderately old/or inexpensive systems.

Thanks. I have now also played with cvt.

That would be a wonderful solution which I imagine can be easily ported to
Kubuntu as well. I will need to study the code for gnome-display-properties,
xrandr, and gnome-settings-daemon to better understand what is involved. I'd
be happy to test what you come can up with.
