If there is any more info needed to debug this, please tell me. It's a really annoying bug, mostly because it shortens the life of my laptop battery.

Why [cat:suspend]? It has nothing to do with suspend, as it doesn't work before suspending either.

Please attach the output of 'ls -lR /sys/class/backlight'.  I suspect the backlight control code is just confused.

    /sys/class/backlight/:
    total 0
    lrwxrwxrwx. 1 root root 0 מאי 10 18:43 dell_backlight -> ../../devices/platform/dell-laptop/backlight/dell_backlight

Can you please install the pmtools package and attach the output of the acpidump command when run as root, please?

acpidump

Looks like this should be using ACPI backlight control but isn't for some reason.

Is it possible to force it to use ACPI backlight control (as a workaround)?

Try booting with the kernel parameter acpi_backlight=video -- looks like yours default to vendor (which uses, in this case, dell-laptop)

Doesn't work with acpi_backlight=video, whatever I click, (lower or higher brightness) the OSD doesn't change, I think it thinks there is only one level possible...

ls -lR /sys/class/backlight
shows "total 0".

I have exactly the same problem with the same machine, with FC13 and now with FC14.
I have read somewhere (cannot retrieve) that upgrading the BIOS fixed the problem for somebody.
My BIOS is at version A02 since delivery.
Updating under Windows seems very easy but I only have Linux on my machine.

Can you please check, Elad, your BIOS version? With this command line given as su:      dmidecode | more
you can see the BIOS version near the top of the second page displayed, no need to reboot the machine.

I won't push you into updating your BIOS if you happen to have a double boot wih Windows. The information is on the Dell Web site ; you will need the "service tag" printed on the back of the computer and far easier to read as "serial number" on the line printed by "dmidecode | more" immediately following the BIOS Version. 

Jacques

My BIOS version is A11, which is the latest version available from Dell.
Problem still exist.

Is this issue still present with the 2.6.40.x F15 kernels?

Today , I was installed Fedora 16 and I give shot for this brightness problem with Intel but still in bug I think because shortcut key not working also manually with use xbrightness , brightness just change when I wrote to powertop --calibrate  while in calibrating powertop can change manage brightness all levels after that I try to find which file control to brightness level and I found in 

/sys/class/backlight/intel_backlight/brightness 

and I try to change value but system not let me do this. and I was said "fine maybe Xrandr or something else control brightness" and I try to find all control but result is zero ? 

Also I have two cards that can be problem I think, because  I tried to Fedora 16 with different machine model is ; hp dv3 series It have two card too but It was working ?

I really try to find every way in Fedora I searched in Google,fedoraforums,bugzilla etc...

My brightness level 0-10  and my level is 5 in Intel but too high and that level can harm to my eyes. I hope we can find solution

Thank you .

First I become root in terminal and ; 

I make brightness_intel.sh  

chmod +x brightness_intel.sh

then I add this line ; 
------------------------------
#!/bin/sh

clear

echo "Enter a brightness value"

read brightness

echo $brightness > /sys/class/backlight/intel_backlight/brightness

echo "Brightness set to $brightness."                                    
---------------------------------
And done ..

 I can manage to brightness level this measure too sensitive 

Example :  If I wrote to "1" to brightness that's too low almost see display and I rised to one by one too 150 and that's much better to low level.

I hope that's helped too other people

Is this still a problem with the 2.6.43/3.3 updates in F15/F16?

Can't check F15, but I know it works on F16 and 17, so I guess you can close this bug.

Thanks for letting us know.
