Red Hat Bugzilla – Bug 108693
Diamond Stealth S220 problem
Last modified: 2007-04-18 12:59:00 EDT
Description of problem:
1. Installation of RH9 freezes when probing DDC.
2. Using Driver "vga" X works, but in an obscure resolution, 120x120 or
something like this
3. Using Driver "rendition" which should be appropriate for the video card
(Diamond Stealth S220) causes this error message:
Symbol xf86SetDDCproperties from module
/usr/X11R6/lib/modules/drivers/rendition_drv.o is unresolved!
I think the problem is caused by broken rendition driver, as stated in the bug
377 in the bugzilla on xfree86.org. This bug was fixed.
Version-Release number of selected component (if applicable):
use video card Diamond Stealth S220 (PCI)
Steps to Reproduce:
1. Install RH9 from CD in graphical mode.
1. Configure card to use rendition driver
X doesn't start, installation freezes.
X working, installation working.
see bug 377 on bugs.xfree86.org
Ok, I read the upstream bug report, and I've generated a unified diff
of the driver between 4.3.0 and current. Doing a quick review of all driver
changes seems to show most of them are purely cosmetic, and the non-cosmetic
changes seem likely to be safe to apply to our 4.3.0 packages. Since this
hardware is very ancient and few users are probably using it, I see no harm
in updating the driver to the current one.
At least that way if users have problems with the rendition driver and they
report them to http://bugs.xfree86.org, they actually stand a chance of
getting investigated and fixed. Older hardware which is being used with
older X servers and older drivers tends to be ignored in bug reports.
The 4.3.0-43 build for Fedora Core will have this fix. I may or may not
be able to squeeze it into RHL 9 erratum currently. If you need an updated
driver for RHL 9 immediately however, I can put one on my ftp space for you
if you like. Just let me know.
Just an additional note that the rawhide XFree86 rendition driver has
had a SEGV bugfix related to DDC for quite a while now, which may or may
not have also worked around this problem. Thought I'd mention that for
completeness as I just noticed I had added a rendition bugfix before and
forgotten about it.
The new CVS driver backport is now in my latest internal development package.
Thanks for your immediate help! Please put the updated driver on your
ftp if it is possible, i am really in need of it.
Here is the new driver. Please update the bug report to let me know
wether it works for you or not.
Thanks in advance.
I tried the new driver on RH9 and FC1 and it works fine on both. There
is possibely a problem with monitor probing, i needed to put a
modeline by hand to obtain refresh rate higher than 60Hz - but i think
it is OK for such old and probably rare videocard.
Fedora installation works (if nofb used), but after reboot X does not
start because of usining driver "vga" - so if you have the same or
similar videocard as i have (Diamond Stealth S220, rendition 2100
chip), replace the fedora rendition_drv.o driver by the new one
linked above and change driver to "rendition" in XF86Config. It works
for RH9 too.
An errata has been issued which should help the problem described in this bug report.
This report is therefore being closed with a resolution of ERRATA. For more information

this bug report if the solution does not work for you.
