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!

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 -> sudo echo 8 > /sys/class/backlight/intel_backlight/brightness bash: /sys/class/backlight/intel_backlight/brightness: Permission denied

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/ total 0 drwxr-xr-x 3 root root 0 Apr 19 21:57 . drwxr-xr-x 4 root root 0 Apr 19 21:57 .. -r--r--r-- 1 root root 4096 Apr 19 21:57 actual_brightness -rw-r--r-- 1 root root 4096 Apr 21 01:52 bl_power -rw-r--r-- 1 root root 4096 Apr 19 21:57 brightness lrwxrwxrwx 1 root root 0 Apr 21 01:52 device -> ../../card0-LVDS-1 -r--r--r-- 1 root root 4096 Apr 19 21:57 max_brightness drwxr-xr-x 2 root root 0 Apr 21 01:52 power lrwxrwxrwx 1 root root 0 Apr 19 21:57 subsystem -> ../../../../../../../class/backlight -r--r--r-- 1 root root 4096 Apr 21 01:52 type -rw-r--r-- 1 root root 4096 Apr 19 21:57 uevent

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

Hi Christopher, (In reply to comment #11) > 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. 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
Chun-Yi Lee: Fn+Left: 0xe0 0x4c 0xe0 0xcc Fn+Right: 0xe0 0x54 0xe0 0xd4
(In reply to comment #15) > 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
