On my Toshiba laptop, booting with an external monitor plugged into the VGA port disables adjustment of the built-in screen brightness setting until reboot, even if the VGA cable is later unplugged. Pressing Fn+F6/F7 to adjust laptop panel brightness pops up the OSD, which does respond to the keypresses, but the actual brightness of the builtin panel does not change if the laptop was booted with an external monitor plugged in. If I boot without an external monitor connected then it works fine. Also, if I originally booted with an external monitor plugged in, powertop reports the panel power setting at the same percentage as the OSD display, but the builtin panel brightness never visibly changes.

Is this fixed on F16? It seems to work for me on my wifes Toshiba.
Still broken for me on F16 on my own Toshiba laptop. Probably/possibly related to the fact that the VGA pipe can't be enabled unless I boot the machine with VGA plugged in.
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
