Description Dan Swanwick 2002-11-14 03:58:52 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
after moving a hard drive from one dell inspiron system to another,
redhat-config-xfree86 failed to correctly determine my hardware, and therefore
couldn't configure my system to start x.

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

How reproducible:
Didn't try

Steps to Reproduce:
1. Change system monitor or video card
2. Run redhat-config-xfree86

Actual Results:  redhat-config-xfree86 exited without provisionally starting x,
and therefore without allowing me to change settings to get a working x

Expected Results:  i should've been able to configure x

Additional info:

video card: ati rage 128 mobility; driver: r128
display: dell inspiron 1400x1050, 24 bit color

What did redhat-config-xfree86 print out on the command line, and please attach
the log (/var/log/XFree86.setup.log) to this bug.

Comment 3 Dan Swanwick 2002-11-14 12:39:10 UTC
turns out it's 100% reproducible. all i had to do was move /etc/X11/XF86Config
to a different filename, quit x, and run the config program.

command line output:

[root@georgia root]# redhat-config-xfree86
*ddcprobe returned bogus values:
ID:   None
Name: None
HorizSync: None
VertSync:  None

Couldn't start X server, trying with a fresh configuration
ID:   None
Name: None
HorizSync: None
VertSync:  None

Error, cannot start X server.

Comment 4 Alexander Larsson 2002-11-15 09:17:41 UTC
Strange. It doesn't find any modes. Since the DCC probe failed is should have
falled back to a SVGA monitor spec.

mharris: Exactly what does:
(EE) R128(0): No valid modes found
(EE) Screen(s) found, but none have a usable configuration.


Comment 5 Brent Fox 2002-12-03 17:33:23 UTC
mharris: ping?

Comment 6 Mark Heslep 2003-02-22 11:02:35 UTC
I observe the same repeatable ddcprobe failure from ..config-xfree86 on my NEC
Multisync FP950 resulting in a fallback to 800x600, however:

A run of  'XFree86 -configure' correctly probes the monitor and produces a
correct /root/XF86config file up to the maximum supported resolution of the
nvidia driver.

Comment 7 Brent Fox 2003-05-27 19:41:27 UTC
Can you try with RHL 9 and see if the problem still exists?

Comment 8 Brent Fox 2003-09-04 20:25:53 UTC
Hmm, well, please reopen this bug is you can reproduce with RHL 9 or with the
Severn beta.  The r128 driver works fine for me with those two releses.

Comment 9 Dan Swanwick 2003-09-04 20:41:01 UTC
I'll upgrade at some point, and report back then. Thanks for following up.
