Red Hat Bugzilla – Bug 495315
Sony Vaio VGN-FW139E Laptop Screen Brightness cannot be decreased
Last modified: 2009-12-18 04:14:26 EST
Description of problem:
Version-Release number of selected component (if applicable): 1.0.6
How reproducible: Use Sony Vaio VGN-FW139E laptop brightness controls
Steps to Reproduce:
1. Use Fn+F5 to decrease brightness
2. Use Fn+F6 to increase brightness
Actual results: Nothing
Expected results: Expect the screen brightness to dim
Additional info: Read here that in Ubuntu, DSDT can be patched - not sure how to do that with Fedora 10:
ACPI client is a small command-line program that attempts to replicate the functionality of the 'old' apm command on ACPI systems. It includes battery and thermal information.
ACPI is not the correct component for this issue. Reassigning.
It seems to me that this is kernel stuff. Reassigning.
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. 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bug reports from releases that are no longer maintained.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 '10'.
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 10'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 10 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:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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no longer maintained, which means that it will not receive any further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.
