Last modified: 2007-04-18 12:32:00 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0; DigExt) Xconfigurator 4.9.16 seg faults and dumps core on Dell PE 8450 with gd5446 chipset. previous verions of Xconfigurator required turning on the "no bitblip" option in XF86Config, and using Xfree3, running "Xconfigurator -- expert --preferxf3" still causes segmentation fault. Reproducible: Always Steps to Reproduce: 1. Install RC2 2. Run Xconfigurator 3. Probe chipset 4. Card listing identifies chipset correctly 5. Hit enter 6. Segmentation fault, core dumped Actual Results: Xconfigurator can't run Expected Results: Write XF86 config file correctly and be able to run X

Does this persist on RC2?
This was found on RC2. Did not occur on previous Betas.
We (Red Hat) should really try to fix this before next release.
What kind of monitor is attached to it? Does it persist if you specify --noddcprobe? Does it persist with Xconfigurator-4.9.17-1, available at http://people.redhat.com/notting/Xconfigurator/ ?
And if it does, can you rebuild Xconfiguratior with debugging info and give us a traceback?
the --noddcprobe flag keeps Xconfigurator from seg faulting. Downloading the new Xconfigurator 4.9.17-1 listed here, Does not help. After the XF86Config file has been written, you have to edit it and put the no_bitblt option in. but X still hangs on startup at a grey screen, curser disappears. Must do a hard boot at this point. Nothing else can be done other than trying to trace the problem by building the source code.
What kind of monitor is attached?
If you build 'ddcprobe' in the kudzu source package, does that also segfault?
Dell M780 Monitor
Will be fixed in kudzu-0.97.7-1; Xconfigurator will need to be rebuilt once this is installed in the build roots.
Xconfigurator no longer seg faults. However attempting to startx works temporarily, but screen goes blank during gnome startup. Activating "no bitblt" option has no effect. Running "Xconfigurator --expert --preferxf3" attempts to use XF86_SVGA then says server does not exist.
Try installing the XFree86-SVGA package.
You need to have XFree86-SVGA installed. And unfortunately, the Cirrus GD 54xx series chips are not well supported.
we are adding Option "NoAccel" for this card.
