Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

log file for updated xserver

this is the log file for the updated xserver where I began to see problems.
This is using my custom xorg.conf file.

without xorg.conf file or duel head

This log file is without a xorf.conf file of my vgs monitor attached. Just the
standard laptop.

Comment 5 louisgtwo 2008-06-18 17:00:15 UTC
Without my custom xorg.conf file or duel head config everything is working fine.
I see no slowdowns at all. Seams to de a duel head config problem. 

On a side note I also do not have direct rendering, I do not even have /dev/drm.
I have opened a separate bug for this. Bug 451887

Comment 6 louisgtwo 2008-06-20 02:07:14 UTC
Without the xorg.conf file both monitors work fine, even dri. The monitors are
mirrors of each other. So something with my xorg.conf file is causing the
problems. How can I get one big desktop without the xorg.conf file?
System-config-display is not working for me at all.

Comment 7 louisgtwo 2008-06-20 03:07:00 UTC
I have pinpointed the problem to the virtual 3200 1200 line in the xorg.conf
file. Without this line the two displays are working fine. But the displays are
lot aligned correctly. I need to have the virual fb bigger. 

Comment 8 louisgtwo 2008-06-23 19:00:56 UTC
After repositioning the monitors one above the other and having a virtual
desktop of 1920 2000 My problems went away. So the xserver is having problems
with the monitors side by side. This worked well with the xserver that
originally shipped with F9. 

Comment 9 Bug Zapper 2009-06-10 01:40:38 UTC
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bug reports from releases that are no longer maintained.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:
