Red Hat Bugzilla – Bug 208157
/usr/sbin/ddcprobe does not find video care - other versions of ddcprobe do find it.
Last modified: 2008-03-26 12:05:32 EDT
Description of problem:
/usr/sbin/ddcprobe does not find video card
ddcprobe from several versions of Knoppix linux
does find the video card -> Matrox Millenium P750 card
Version-Release number of selected component (if applicable):
Fedora Core 6 Test 3
ddcprobe never finds card.
Steps to Reproduce:
1. run /usr/sbin/ddcprobe
Monitor autoprobe results
Monitor autoprobe failed.
Data on video card and monitor
ddcprobe from several versions of Knoppix linux all work
and find the card.
vesa driver does not work with Matrox Millenium P750 card in
Fedora Core 6 Test 3. It works with Fedora Core 5!!
My ddcprobe doesn't list anything either. Nor I can't get picture - probably
because xorg.conf relies on ddcprobe. No vesa nor radeon give anything, goes
out of range of Dell LCD. I've got ATI dualhead card.
These used to work in fc5. :-(
Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

The above two files are tar'ed and gzipped (.tgz)
I digged this a littlebit and have a feeling that 'autodetection' mentioned in
xorg-x11-drv-ati has something to do with that. Could not find my card
in /usr/share/hwdata/videoaliases/radeon.xinf but adding it manually there
didn't help. (got numbers with lspci -n)
Looks like ddcprobe uses kudzu, need to dig more later.
perhaps someone could switch the version of this bug to released one, people
would find this if filtering test releases out.

What are the results of running kudzu -p -b pci -c video?

ddcprobe fails to detect Matrox G450 card on different system
# kudzu -p -b pci -c video
desc: "ATI Technologies Inc R580 [Radeon X1900 XT] Secondary"
desc: "ATI Technologies Inc R580 [Radeon X1900 XT] Primary"
that video.xdriver line comes from my own addition to radeon.xinf, I guess
right place to it should be in vga.xinf as I understood that vesa is the only
possible driver for this card.
I get the same error with a totally different graphics card and monitor.
And this gets printed in /var/log/messages every time I run ddcprobe:
python: obsolete kudzu ddcProbe called
Fedora Core 5 and Fedora Core 6 are, as we're sure you've noticed, no longer
test releases. We're cleaning up the bug database and making sure important bug
reports filed against these test releases don't get lost. It would be helpful if
you could test this issue with a released version of Fedora or with the latest
development / test release. Thanks for your help and for your patience.
[This is a bulk message for all open FC5/FC6 test release bugs. I'm adding
myself to the CC list for each bug, so I'll see any comments you make after this

Ok, I can't.
But someone should...
Not going to fix this one, sorry. ddcprobe is going away. Use 'kudzu -p -c
video' for video device detection.
