Hi, Bill,

could I ask for /etc/X11/xorg.conf as well, please? Thanks.

Yeah, reproducible here.  No idea why though, only thing I can think of is sync
polarity.  +hsync +vsync looks wrong.
Comment 5 Tom London 2007-04-12 18:47:13 EDT
I'm seeing a similar issue with Thinkpad X60.

It appears that 'intel' is not quite getting the rates set properly.

If I set to 1280x1024@75, it seems to set it to 1280x1024@78.8 (as reported by
the on screen display of my two LCD monitors).

When in this mode, doing 'xrandr --rate 60' seems to make it work, but actually
sets it to 1280x1024@60.1 (or something close).

1280x1024@75 works OK with 'i810'.

This possibly related?
Comment 6 Jesse Barnes 2008-01-10 17:09:55 EST
The upstream intel driver and Xorg have some new quirks to deal with bad sync 
polarities.  Would be good to re-test and see if the problems still occur.
Comment 7 Bill Nottingham 2008-01-10 17:17:42 EST
Still happens on F8.
Comment 8 Bug Zapper 2008-05-13 22:35:44 EDT
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
Comment 9 Bug Zapper 2009-06-09 18:26:39 EDT
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
Comment 10 Bug Zapper 2009-07-14 12:48:19 EDT
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
