Zhang Rui, thank you for taking a look at this. I do not have the skills to determine if this is a duplicate or not. However, here is the information requested in that bug.

echo 5 > /sys/class/backlight/acpi_video0/brightness
bash: /sys/class/backlight/acpi_video0/brightness: No such file or directory
sudo echo 5 > /sys/class/backlight/acpi_video0/brightness
bash: /sys/class/backlight/acpi_video0/brightness: No such file or directory

When REMOVED "acpi_backlight=vendor"
 # ls /sys/class/backlight
acpi_video0  intel_backlight

When ADD "acpi_backlight=vendor"
 # ls /sys/class/backlight
intel_backlight
 
Please try the following 2 command when ADD "acpi_backlight=vendor":
# echo 5 > /sys/class/backlight/acer-wmi/brightness 
echo 5 > /sys/class/backlight/acer-wmi/brightness 
bash: /sys/class/backlight/acer-wmi/brightness: No such file or directory
sudo echo 5 > /sys/class/backlight/acer-wmi/brightness 
bash: /sys/class/backlight/acer-wmi/brightness: No such file or directory
# echo 5 > /sys/class/backlight/intel_backlight/brightness

sudo echo 5 > /sys/class/backlight/intel_backlight/brightness
bash: /sys/class/backlight/intel_backlight/brightness: Permission denied

1) if the brightness works when you boot the kernel with both
acpi_osi="!Windows 2009" and acpi_osi="!Windows 2006" ?
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="!Windows 2009" acpi_osi="!Windows 2006""
sudo update-grub
/etc/default/grub: 11: 2009 acpi_osi=!Windows: not found

2) if the brightness works when you boot the kernel with acpi_osi="Linux"?
I can adjust the brightness via the keyboard but not by the brightness applet.

Please change the Status to better reflect the nature of this bug as I was not given the appropriate permissions to do so.
Comment 5 Christopher M. Penalver 2012-04-06 20:04:47 UTC
Zhang Rui, still reproducible in:

 lsb_release -rd
Description:	Ubuntu precise (development branch)
Release:	12.04

cat /proc/version
Linux version 3.4.0-030400rc1-generic (apw@gomeisa) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5.1) ) #201203312035 SMP Sun Apr 1 00:43:10 UTC 2012

While I now have more options to choose from in the Status: picker (NEEDINFO, RESOLVED, VERIFIED, REJECTED, DEFERRED, CLOSED) it seems the most appropriate  is NEW?

Not suggest use 'acpi_osi', it's last resort if 'acpi_backlight=vendor' doesn't work.

> Please change the Status to better reflect the nature of this bug as I was not
> given the appropriate permissions to do so.

Please removed any acpi_osi, e.g. acpi_osi="Linux", only put 'acpi_backlight=vendor'.

Then try the following command by "root" account:
  sudo echo 8 > /sys/class/backlight/intel_backlight/brightness

If it works, I will put your machine to quirk list in acer-wmi driver.

On the other hand,
If intel_backlight/brightness works to you by manually change brightness value, but the brightness applet doesn't work, that's the user space problem, not kernel issue.

Thanks!

-> I'd be happy to but I don't know what to check for specifically, let alone what to change it to.

Then try the following command by "root" account:
  sudo echo 8 > /sys/class/backlight/intel_backlight/brightness

->
sudo echo 8 > /sys/class/backlight/intel_backlight/brightness

It's should not happen if you really use 'root' acount to run the above command.
Did you use 'su root' for change to root account?

Could you please list the result through the following command?
  # ls -la /sys/class/backlight/intel_backlight/


Thanks

Chun-Yi Lee, in order to access the root account a 'sudo su' was required.

ls -la /sys/class/backlight/intel_backlight/

The file permission has no problem no your machine.

As you said, please kindly try 'sudo su' or 'sudo su root', then run:

 # sudo echo 8 > /sys/class/backlight/intel_backlight/brightness

If it works, then I will add this machine to quirk table.

Chun-Yi Lee, performing at the Terminal:
sudo su

then:
sudo echo 8 > /sys/class/backlight/intel_backlight/brightness

causes the brightness to drop dramatically.

Good! 
That means intel drm driver works on your machine to control brightness, I will add your machine to quirk table in acer-wmi.

On the other hand, 
Please removed any acpi_osi, e.g. acpi_osi="Linux", only put 'acpi_backlight=vendor'.
Then test your Fn+left/right key to control brightness, if it still doesn't work, then it's a user space issue. There should have a user space application to take care brightness change.
e.g. Gnome-power-management or Gnome-settings-daemon

Thanks

Forgot one thing, even we confirm the intel drm driver works on your machine, we also need to check the keycode of Fn+left/right are really emitted to user space.

Please kindly do the following check:

 + Add kernel parameter 'atkbd.softraw=0' to /boot/grub/menu.lst
 + Switch to any console, e.g. Ctrl+Alt+F1, login by root account. Run:
    # showkey -s
   Then, press Fn+left/right key to monitor what's the code show up on screen.

Thanks
Comment 15 Christopher M. Penalver 2012-05-05 18:40:32 UTC
Chun-Yi Lee:

Fn+Left:
0xe0 0x4c 0xe0 0xcc

Fn+Right:
0xe0 0x54 0xe0 0xd4

OK, I just checked the keymaps/acer* in udev, the above 2 scan code didn't set in transfer map.

Per my experience, acer laptop always direct emit brightness up/down key code to user space when press Fn+left/right key. We don't need add key mapping to udev.

Another situation is user space application/daemon direct listen uevent from kernel when brightness changed.

Please check your distro community or maintainer, make sure you cann't grab Fn+left/right key on user space. I know have 2 way can verify:

 + Open a terminal window, run 'xev', then press Fn+left/right.
    Look at does it show up any key press event on xev?

 + If your distro still using HAL, then run 'lshal -m', then press Fn+left/right
    Look at it show up 'condition ButtonPressed = brightness-up'


Please contact with distro community, and make sure you cann't grab key event through xev (means X-window cann't grab your key event). If the answer is yes, then back to here, we can discuss add the scan code 0x4c, 0x54 to udev keymap.


Thanks
