Description Jonathan Underwood 2007-08-09 14:29:38 EDT
Description of problem:
I have a Dell XPSM1210 laptop. Running powertop with an external LCD screen
attached and the internal (LVDS) screen off results in the external monitor
being switched on and off at each refresh of powertop. This is using the xorg
intel driver. 

Version-Release number of selected component (if applicable):
powertop-1.7-3.fc7

Will attach lspci output separately. Note:

Comment 5 Jonathan Underwood 2007-08-09 16:40:04 EDT
I should have added that with both the LVDS and external monitor on, ONLY the
external monitor is switched on and off at each refresh - the LVDS stays on
thru'out.
Comment 6 Bug Zapper 2008-05-14 09:55:55 EDT
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '7'.

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 7'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 7 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. 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. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists.

Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs:
http://docs.fedoraproject.org/release-notes/

The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
