Description Jason Vas Dias 2005-01-03 13:51:16 EST
Description of problem:

I yum upgraded rawhide 2004-11-1 to 2005-1-2 :
FROM:                                 TO:
     system-config-display 1.0.23-1      1.0.24-1
     kernel-2.6.9-1.1009_FC4             2.6.10-1.1063_FC4
on an IBM ThinkPad T41 laptop 
and my ATI Mobility Radeon driven display resolution 
changed from 1280x1024 to 800x600. 

There was no way to increase the resolution with system-config-display. 

An /etc/X11/xorg.conf file was created during the upgrade with
the new resolution restriction; simply replacing this file with
/etc/X11/xorg.conf.backup fixed the problem and the display is 
now back to 1280x1024 and is working OK .

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

How reproducible:

Steps to Reproduce:
1. Upgrade to latest rawhide of 2005-01-03
Actual results:

Display on ATI Radeon Mobility LCD changes from 1280x1024 to
800x600 , and there is no way to increase resolution with 

Expected results:

Display resolution should not be changed during upgrade, 
and system-config-display should let you increase resolution
to maximum value supported by card.

Comment 1 Paul Nasrat 2005-01-03 14:16:52 EST
Please add output of running as root:

kudzu -p -b ddc 

It looks as if you have an lcd monitor which may not support ddc, did
you ever use s-c-display to change monitor?
Comment 2 Jason Vas Dias 2005-01-03 14:46:59 EST
I clean installed the rawhide of @ 2004-10-01 using
system-config-display through anaconda, but since then
never changed the display settings or xorg.conf at all .
It was only when I upgraded to the latest 2005-01-03
rawhide that I lost  my 1280x1024 resolution and had
to copy back the original xorg.conf. 

Here's the output you asked for:
$ kudzu -p -b ddc
class: VIDEO
bus: DDC
detached: 0
driver: unknown
desc: "ATI Technologies Inc. P7"
mem: 32704
Comment 3 Paul Nasrat 2005-01-03 15:33:15 EST
We're certainly not able to probe your monitor, so you'd need to reselect it
manually if the settings were clobbered - which they seem to have been.  Not
much we can do about that atm sadly. I assume this was done at install.

Selecting an appropriate LCD monitor in s-c-display should enable you to
reconfigure back to the higher resolutions (we calculate available modes based
on card/monitor/video memory).

Was xorg-x11 updated at any time.   IIRC there was a bug at one point with it
moving an existing config out of the way or did you run system-config-display
--reconfig. , I'm trying to ascertain why the config got replaced.

Can you attach rpm --last -qa.  I'll also try to reproduce based on the details
you give.
Comment 4 Jason Vas Dias 2005-01-03 16:59:39 EST
The xorg.conf was replaced during the 'yum upgrade' - that's
the major problem of this bug as far as I'm concerned. I know
if I set the monitor type I'd be able to select 1280x1024 mode -
but the xorg.conf should not have been changed during the yum 
I've appended a gzipped tar file containing the 'rpm --last -qa'
output, as well as the yum logs on my system.

I had the same thing happen. 
Comment 7 Adam Jackson 2006-09-21 18:37:55 EDT
This should be working as of FC6 test3.  Please reopen if this issue still
occurs for you.
Comment 8 Adam Jackson 2007-04-03 14:22:37 EDT
NEEDINFO timeout, resolving as INSUFFICIENT_DATA.  If you are still experiencing
this bug in FC6 or FC7, please reopen.  Thanks for the report!
