xvidtune FPE coredump
Last modified: 2007-04-18 12:46:45 EDT
In 7.3.94 ((null)) fresh install + full up2date I get xvidtune crash (before popping up any X windows): (gdb) run Starting program: /usr/X11R6/bin/xvidtune (no debugging symbols found)...(no debugging symbols found)...(no debugging symbols found)...

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.

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
*** Bug 76608 has been marked as a duplicate of this bug. ***
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.
