Xorg.0.log always has those kind of lines after "EDID for output VGA"
when it doesn't get any EDID information. Take a look at
http://launchpadlibrarian.net/26967510/Xorg.0.vga.log for how it looks
when the EDID information is acquired properly (in that case the there
is only a VGA connected, it still prints "EDID for output HDMI-1" with
no EDID information afterwards). Note especially that it dumps the EDID
in hex, so that it possible to verify that it was interpreted right. The
EDID in hex should also be written out by `xrandr --verbose` (the
mentioned log is from bug 378617, take look at the xrandr --verbose
output there when the monitor is connected via VGA).
You may check if you can get any EDID information using the tools get-
edid (from the read-edid package, available for amd64 at
https://launchpad.net/~intuitivenipple/+archive/ppa/ (see bug 242043),
or ddcprobe (from the xresprobe package).
We also would like to know excactly what kind of Sony Vaio you have.
