Description of problem: gnome-power-manager-2.29.91-2.fc13 was supposed to re-enable HAL support, but it failed to do that. From build.log: HAL (brightness) support: no To build gnome-power-manager with HAL support, '--enable-hal' must be passed to configure. (BTW, the current spec file passes the parameter '--enable-policykit' which is not recognized by configure, so it can be removed.) When you add '--enable-hal', you'll notice it does not compile anymore because of a trivial error. This commit in upstream git fixes it: commit fdcf156c85c10a6053b7364d882611df07000343 Author: Chris Coulson Date: Tue Mar 2 08:59:31 2010 +0000 Declare GError in gpm_brightness_hal_init to fix build failure I made a scratch build and tested that it works fine then: http://koji.fedoraproject.org/koji/taskinfo?taskID=2048364 Version-Release number of selected component (if applicable): gnome-power-manager-2.29.91-2.fc13 How reproducible: always Steps to Reproduce: 1. Test on a system where there's no brightness property in xrandr. 2. Try to change brightness using hotkeys, or try to find a brightness slider gnome-power-preferences Actual results: Brightness cannot be changed, there's no slider. Expected results: Brightness hotkeys work, there's a slider in g-p-preferences.

I am still unable to change brightness using [jonesn@snowdon2 ~]$ rpm -q gnome-power-manager gnome-power-manager-2.29.91-2.fc13.x86_64 This worked initially. will refer to dup bug ref.
Nigel, gnome-power-manager-2.29.91-2.fc13.x86_64 is known to have the bug. The scratch build with the fix has ".m1" in the release field.
Many thanks. Id missed the m1. Duh! The build works great - brightness control now fine again -- thanks.
