Description of problem: In the current situation, sliding the brightness bar in gnome-power-manager causes a lot of screen flickering, since it goes to 100 % for invalid values. Upstream bug report contains a working fix, which applies cleanly against kernel-2.6.24-0.133.rc6.git8.fc9. It would be nice if the fix could be backported to F8 kernel as well.
Adding ACPI metadata.
Patch has now been merged to acpi test branch.
Created attachment 291191 [details] the patch in question, in case someone wants to test
So, are there any chances this patch hits Fedora kernel before it gets merged upstream?
CCing upstream submitter.
The patch in comment #3 works fine for me, and I'd also appreciate it being merged to the Fedora kernels. g-p-m backlight management is just unusable as it is now for ACPI video driver users.
The patch has been updated, new one is even better. It would be very cool if this patch could be applied to Fedora kernel along with the one mentioned in kernel bug #9614. These two greatly improve the backlight experience.
Fixed in 2.6.23.14-132
The backlight issues are fixed, thank you. Not sure if this bug should be closed, or stay open until the fixed kernel hits the repositories.
kernel-2.6.23.15-137.fc8 has been submitted as an update for Fedora 8
kernel-2.6.23.15-137.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
