Description Flags
the patch in question, in case someone wants to test none

Description Julian Sikorski 2008-01-04 06:45:03 EST
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.
Comment 2 Julian Sikorski 2008-01-09 07:39:12 EST
Patch has now been merged to acpi test branch.

Comment 4 Julian Sikorski 2008-01-12 04:35:15 EST
So, are there any chances this patch hits Fedora kernel before it gets merged
upstream?
Comment 5 Julian Sikorski 2008-01-12 04:42:47 EST
CCing upstream submitter.
Comment 6 Danny Baumann 2008-01-12 07:26:47 EST
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.
Comment 7 Julian Sikorski 2008-02-02 11:03:11 EST
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.
Comment 8 Chuck Ebbert 2008-02-05 19:50:08 EST
Fixed in 2.6.23.14-132
Comment 9 Julian Sikorski 2008-02-06 04:27:46 EST
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.
Comment 10 Fedora Update System 2008-02-10 22:34:14 EST
