Description Aleksey Nogin 2002-09-16 17:39:21 EDT
In 7.3.94 ((null)) fresh install + full up2date I get xvidtune crash (before
popping up any X windows):

(gdb) run

What video card do you have?  Also, could you please attach your
config file and X log file.

It appears DDC probe is being done, but perhaps the monitor is
returning invalid data, or data unexpected by the app.

I'll look into it once I've got your info.  Thanks.

Comment 3 Aleksey Nogin 2002-12-14 16:02:35 EST
Ah, sorry, completely forgot about needing to respond to this.

Video card: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]
(see bug 79141 attachment 87648 [details] for lspci -vv output).

X config: see bug 79141 attachment 87647 [details]

X log: see bug 79141 attachment 87645 [details] for a log showing the X startup using this
exact configuration. Please let me know if you need a complete log, with the
stuff that xvidtune would cause to appear in there.

P.S. I do not really know how this works, but my interpretation of the events is
that the radeon driver leaves it to something external (BIOS, video card, etc)
to figure out what's the right vsync/hsync rates to drive the LCD, so xvidtune
gets all zeros and crashes when trying to divide something by it.

P.P.S. The problem is still there with XFree86-4.2.1-9

Comment 7 Mike A. Harris 2004-09-24 13:34:30 EDT
We believe this issue to be resolved in our currently shipping
OS releases.  Please upgrade to Fedora Core 2 or later, and if this
issue turns out to still be reproduceable, please file a bug report
in the X.Org bugzilla located at http://bugs.freedesktop.org in the
"xorg" component.

Once you've filed your bug report to X.Org, if you paste the new
bug URL here, Red Hat will continue to track the issue in the
centralized X.Org bug tracker, and will review any bug fixes
that become available for consideration in future updates.

Confirming, I can no longer reproduce this in FC2 + all updates.
