Description Sam Varshavchik 2002-12-14 19:11:23 UTC 
Description of problem:

The gingin2 installer did not read my monitor frequency, which had to be entered
manually.  After installing, gingin2's ddcprobe outputs garbage.

ddcprobe on a box running psyche, when hooked up to the same monitor, displays
the proper monitor frequencies.

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

0.67-1

How reproducible:

Always


Steps to Reproduce:

Run ddcprobe

Actual results:

Videocard DDC probe results

Height(mm): 2550

Expected results:

Results from another box running psyche (rhpl-0.51-1), hooked up to the same
monitor:

Comment 1 Bill Nottingham 2002-12-19 21:39:11 UTC 
Does it work the same on the other box *with the same graphics card* as in the
box where it fails?
Comment 2 Sam Varshavchik 2002-12-21 02:39:17 UTC 
I swapped the cards between the two boxes.  gingin2 ddcprobe reports correct
frequencies with the TNT card, and the psyche ddcprobe reports garbage with the
3dfx card; so the problem appears to be the 3dfx card.

I do note that up until gingin1 the anaconda installer was able to read the
monitor frequencies succesfully.

psyche with 3dfx voodoo 3500:

Comment 3 Jeremy Katz 2002-12-29 07:47:17 UTC 
ddcprobe is just a very thin wrapper around kudzu doing DDC probing so these are
the values that kudzu is returning
Comment 4 Bill Nottingham 2002-12-30 06:10:27 UTC 
Hm, it works with the first beta, but not with the second? What about the third? :)

Arjan, did anything change in vm86 in the kernel recently?
Comment 5 Sam Varshavchik 2002-12-30 07:17:36 UTC 
No, beta3 was when I first noticed the problem.  I do not recall any issues with
beta or beta2.
Comment 6 Bill Nottingham 2002-12-30 20:30:25 UTC 
OK, previously you said 'gingin2', I presumed that meant beta2.
Comment 7 Bill Nottingham 2005-09-23 19:48:38 UTC 
Apologies for the slow response. Please attempt to reproduce this problem on a
currently supported release, such as Fedora Core 4. If it does still happen,
please open a new issue.
