This is still true with the Radeon driver in Natty. There's no
BACKLIGHT property exposed on the LVDS interface.
Gnome Power Manager itself now works around it, with gnome-backlight-helper.
KDE also now somehow works around it, as well.
So, the user-facing portion is fixed, but the original

Title:
[lucid] Broken backlight control with Radeon open-source
Dana, the fn-key problem that you describe here also appeared when I
went from Karmic to Lucid on my HP ProBook 4510s, which has an ATI
Mobility Radeon HD-4330. The fn-key problem disappeared after I
installed ATI Catalyst Display Driver version 10.6, which I downloaded
from the AMD support site.
It looks like radeontool fails silently, instead of telling the user to run it
under sudo. I also had to escape the asterisk to pass it to radeontool:
sudo radeontool match \*
Here's my radeontool output on 2.6.34-rc5 kernel from kernel-ppa -- this
is the broken case.
I can't seem to recall a
More correctly, I can't remember _whether_ it ever worked before.

I have this bug (turning brightness up and down with Fn F10 and Fn F9 does not
work) on both up-to-date ubuntu with fglrx and kubuntu with opensource driver
on HP 6930p with ATI 3450.
radeontool regmatch '*' produces on both systems only this:
mapping ctrl region
without any other messages.
Hi,
I have this bug too. Please, tell me what information is needed and the
steps to obtain it.
Regards.

On HP ProBook 4710s (ati hd4330 with fglrx driver) I have a similar problem:
- can't control the lcd backlight using gnome-power-manager
- can't control the lcd backlight using xbacklight
- CAN change the backlight using 'echo -n 0
/proc/acpi/video/DGFX/LCD/brightness'
- when switching to

Hi Dana, okay, radeontool might be useful in debugging this. After
installing it, you run it like this:
radeontool regmatch '*' regdump_good.txt
radeontool regmatch '*' regdump_broke.txt
Run it two times. Once when you have a good, working screen (for any
driver including -vesa), and

With the deprecation of hal, gnome-power-manager must rely on the

To clarify, there are two interacting bugs here: One is that Radeon
doesn't support BACKLIGHT, and the other is that the old HAL-based way
no longer works. The preferred action would be to fix the former,
rather than the latter.
