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.

Xorg.0.log _after removing the xorg.conf

I removed the xorg.conf and then this new log file is created after logging out
and logging in.

Thanks for the response.I have attached the requested files.
Comment 7 Aman 2007-11-13 12:33:48 EST
I want to mention another point here, the problem also appears when the screen 
saver is about to run, when i lock/unlock my session.
Comment 8 Orion Poplawski 2007-11-19 18:27:57 EST
We're seeing this on a Dell Latitude D610 with a 915GM running F7.  Love to see
it fixed.
Comment 9 Aman 2007-11-20 03:07:53 EST
My problem is solved by changing the display driver from Intel-Experimental
driver to i810 driver.
Comment 10 Jesse Barnes 2008-01-10 18:34:05 EST
Can you try the latest git bits?  We've pushed several backlight fixes 
recently, including some that sound like they'd fix your problem.

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  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bug reports from releases that are no longer maintained.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 '8'.

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 8'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 8 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 13 Bug Zapper 2009-01-09 02:23:41 EST
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
