Description Nerses Gevorgyan 2010-06-20 00:42:49 EDT
Description of problem:

Back light on the MSI Wind N011 netbook blinks indefinitely if power cord is pluged in or unpluged. Or user tries to change screen brightness using function keys.

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



How reproducible:


Steps to Reproduce:

Plug or unplug power cord or change screen brightness using function keys. Also can happen if netbook is left for some time. I suppose when the screen saver is activated.
Actual results:

The screen will blink indefinitely changing the brightness from 0% to 100% and back.

Expected results:

ACPI screen brightness changes should work flawlessly. User should be able to change the screen brithness using function keys.

Additional info:

It was normal under FC8 on the same netbook.

Netbook: MSI Wind N011

Comment 1 Bug Zapper 2010-11-03 09:02:16 EDT
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  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bug reports from releases that are no longer maintained.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 '12'.

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 12'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 12 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 2 Bug Zapper 2010-12-03 08:47:03 EST
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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no longer maintained, which means that it will not receive any further 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.
