Backlight/Brightness Issues - Packard Bell: EasyNote TE

Hey, I've done a little searching around for this before posting this topic, and read many things such as installing xbacklight (which didn't work for me) and adding some sort of vendor=backlight? or something into my GRUB (I couldn't figure out how to do this), can anyone help me here? Thanks!

Re: Backlight/Brightness Issues - Packard Bell: EasyNote TE

Post output of

lspci -knn | grep -EiA2 vga

We'll go from there.

EDIT:  I assumed that you could actually get it up and running...which may be careless of me.  If you cannot actually see the screen to boot into a working system, use the "e" button at GRUB.  This will allow you to add kernel parameters.  You may need to add "nomodeset" after the "..... ro" line in GRUB to get it to at least be visible after booting.

The devil is in the details. wink  Please be as specific as possible when explaining problems.

I'm not sure if you are referring to your screen brightness which you cannot alter with your keyboard.
If you are, try this

sudo setpci -s 00:02.0 F4.B=XX

Where XX is the percentage of your screen brightness.

Re: Backlight/Brightness Issues - Packard Bell: EasyNote TE

Hello, thanks for the speedy replies!
Here is the output of the vga command

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0106] (rev 09)
	Subsystem: Acer Incorporated [ALI] Device [1025:0649]
	Kernel driver in use: i915

And yes, I am referring to the screen brightness, I'm not too bothered about the keys at the moment as I can map the keys later on, it's just everything I try won't allow me to adjust the screen brightness. The setpci command you gave me also didn't work sad.
Thanks guys.
