I'm trying to control my Netbook's brightness using terminal.
This is the output of "ls /sys/class/backlight" command:
intel_backlight
Here's the output of "sudo lspci -vnn | grep -A10 VGA" command:
00:02.0 VGA compatible controller [0300]: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller [8086:a011] (prog-if 00 [VGA controller])

Expansion ROM at <unassigned> [disabled]
Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit-
Capabilities: [d0] Power Management version 2
Kernel driver in use: i915
I've tried this:
echo 5 | sudo tee /sys/class/backlight/intel_backlight/brightness
This:
xbacklight -set 50
This:
sudo setpci -s 00:02.0 F4.B=7f
All these give no output message.
I added "acpi_backlight=vendor" to kernel paramiter.
But nothing worked. Please help
