Hi, xresprobe is no longer used in Hardy Heron, the development version
which will become Ubuntu 8.04. Because of that I'm closing this bug.
Please test Hardy (alpha3 or later), and if your hardware still fails to
get a correct resolution (or if it drops to failsafe mode), file a bug
against the
Thanks for you effort and patches :-)

My bad - ddcprobe.sh is *not* checking for the _output_ code of 1 but
the error code of 1. So it's not actually handling this error
condition properly.
Further, looking at the EDID 1.1 spec (or, rather, Wikipedia's report
about it), it clearly says that in the 0 case in the switch above, it's
Here is a fix for this issue. It turned out that in early versions of
EDID, 'aspect=0' was used to indicate a 1:1 aspect ratio, but in later
versions like 1.3 and 2.0, they redefined it to mean a 16:10 aspect
ratio. I guess ddcprobe was developed prior to this change, so was just
assuming 1:1
Aha, I see that the relevant code for this is here, in ddcprobe.c:
for(i = 0; i 8; i++) {
...
switch(edid_info-standard_timing[i].aspect) {
case 0: aspect = 1; break; /*undefined*/
Should be fixed with the newest xresprobe :
Accepted:
xresprobe 0.4.24ubuntu6 was ACCEPTED.

It sounded strange, because I've thought problem is not in some shell
script, but in ddcprobe binary. Problem it, it defaults to 1,0 ratio, if
it can't find correct one via EDID. OK, real problem is it can't find
correct one. Maybe the best thing you can do is use Xorg autodetection
and rewrite

res:
I've also seen reports of a 1680x1680 variant.
Another thing to get details from is get-edid:
sudo apt-get insteall read-edid
get-edid | parse-edid
I'm interested in if this gives the same results; if so, then the error
is likely to be something with the hardware. If not, then it's a bug in
Can you please attach the output from the following? xresprobe driver,
ddcprobe, xrandr.
Also, run dexconf -o /tmp/dexconf-xorg.conf and attach that file.
This is an odd bug, but I think I've seen it mentioned by others. There
must be a logic bug resulting in 1440x1440 rather than 1440x900.
