Description D. Hugh Redelmeier 2003-04-28 02:41:48 UTC

Description of problem:
I'm having a lot of problems with my setup (Radeon 9000, two monitors, RHL9). 
In desperation, I added
    Option  "DDCmode" "false"
to one of the Monitor sections.  This caused X to segfault.

I put this option right after
    Option      "dpms"
This latter option was processed just before the segfault

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.put the option in XF86Config

Actual Results:  (**) Option "dpms"
(**) RADEON(0): DPMS enabled
(II) RADEON(0): Direct rendering disabled
(==) RandR enabled

   *** If unresolved symbols were reported above, they might not
   *** be the reason for the server aborting.

Fatal server error:
Caught signal 11.  Server aborting

Additional info:

I will attach my XF86Config and /var/log/XFree86.0.log

hmm.  Something else is going on: I have been able to use the option without X
crashing.  Will report when I figure out more.

Video driver options go in the video driver "Device" section of the config
file, not in the Monitor or ServerFlags sections.

Comment 5 Mike A. Harris 2003-04-28 08:51:28 UTC
XFree86-Servers doesn't exist in Red Hat Linux 8.0 or 9, reassigning to

Comment 6 D. Hugh Redelmeier 2003-04-29 03:16:00 UTC
Thanks Mike.  Moving the option eliminates the crash.
Still, crashing is a bug, I'd say.

Comment 7 Mike A. Harris 2003-05-14 09:45:09 UTC
An X server crashing due to being misconfigured might be a bug, but it is
an extremely low priority bug which isn't worth engineering time to investigate
and fix, when there are hundreds of bugs open which actually prevent users from
using X, or are much more serious.

Please file this bug report upstream at http://bugs.xfree86.org for the
community of X developers to fix it.

Our official workaround for this problem is to not misconfigure your X server
in a bogus manner, and it will work properly.
