Try adding
Code: [Select]
nomodeset acpi_backlight=vendor to your kernel options in menu.lst

Quote from: djohnston modified
su -
cd /boot/grub
cp menu.lst menu.lst.backup
kwrite menu.lst

Find the line beginning with "kernel". The line below is an example.

kernel (hd0,1)/boot/vmlinuz BOOT_IMAGE=linux root=LABEL=PCLOS quiet acpi=on resume=LABEL=SWAP splash=silent vga=792

Add nomodeset acpi_backlight=vendor to the end of the line so that it reads:

kernel (hd0,1)/boot/vmlinuz BOOT_IMAGE=linux root=LABEL=PCLOS quiet acpi=on resume=LABEL=SWAP splash=silent vga=792 nomodeset acpi_backlight=vendor

Save the file and reboot.

If no joy remove that line and try acpi_backlight=Linux

Sorry to hear that.  Remove the options line you added if you think its causing additional issues.  Just curious, if you enter your Bios utilities screen does brightness keys work there?  Does brightness keys work during Grub boot screen?

Also setting a brightness applet into your panel is a no go? Yeah, I keep seeing this bug being reported at multiple forums. It may be a matter of waiting for the Linux 3.0 kernel to be available for install.  If I come across anything new I'll be sure to post here.

Refresh:
Who now , how HAL works , can you write, how ?
example:
http://www.linlap.com/wiki/hp+elitebook+8540w
and HAL and  30-keymap-hp.fdi  are in pclinux  ...
<append key="input.keymap.data" type="strlist">e017:brightnessup</append>   <!-- FnF8 (FnF10 on 6730b) (brightness up) -->
So this key in Hal  exist,
but how to check hal starting ? how to check key if it works ?
How to find file - command which brightens the monitor.

Why ? What should show this ?   acpi_backlight=Linux
why not xbacklight -set value , example xbacklight -set 50

How this work?
This command edit file in  /sys/class/backlight/... or /proc/acpi/video/VGA/LCDD/...  ?
These files exist only on laptops?

Quote
actual_brightness  brightness         max_brightness     subsystem/    uevent            
bl_power           device/            power/             type

What if He don't have this files?

He need only xbacklight installed?
He don't need add xbacklight -set value  in /etc/rc.local ?
I don't see backlight in synaptic , maybe can xbacklight ? This is in synaptic.
This is this same?
What doing  acpi_osi=Linux ?

Edit:
I find
acpi_osi=Linux
Tells the Advanced Configuration and Power Interface (ACPI) that the Operating System Interface (OSI) is Linux.

acpi_backlight=vendor
Tells the system to use the vendor-specific driver for the backlight instead of the system's default driver.

So updates. Kernel is running down all the keys for HP 6735s under PCLinuxOS 2012 is 2.6.38.8-pclos3.bfs. Cheers and thanks again for your help and everyone direction to solve the problem, without you I would not know even 10% of what I know about Linux.

PS: Kernel is available in the repository

Problem is with 3.2.18 kernel,
and He don't have  file in  /sys/class/backlight/... , but I don't know - whether it could be the problem?


Admin or Mod please mark Solved.
