Intel driver Problems and Mint 17

[Георги]

Hello!

I am new in Linux and I really don't understand "how it is going on here". I bought a Laptop, HP 250 G2 with CPU Intel Celeron N2810.
The problem is that, the brightness the Monitor is always on 100%. I thing that I need drivers from Intel - I have found something:
I installed thatq but there is not a Linux Mint Quiana distribution (* 14.04, 64-bit for Ubuntu ): https://01.org/linuxgraphics/downloads/ ... .0.6-linux
I have also found that, but there are too many packages... to install?: https://01.org/linuxgraphics/downloads/ ... ck-release
And I have also found something that muss I do, the Program to "find" our Distribution : http://www.webupd8.org/2013/04/how-to-u ... ivers.html

But I am new here and I don't know what to do here and how to solve the problem with the drivers. Thank you a lot; I really don't need anythng more (the bluetooth I need too, but it is not so crucial).

Linux Mint Qiana is based on Ubuntu 14.04
What works in Ubuntu 14.04 will work in Mint 17

To get the correct driver open Menu > Administration > Driver Manager

I would look at this tutorial first and see if you can change backlight settings http://forums.linuxmint.com/viewtopic.p ... 48#p933148

It isn't always the fault of the driver, especially with Linux

If the tutorial does not help, open a terminal window and enter this and post the results

Code: Select all

for interface in /sys/class/backlight/*; do echo $interface; cat $interface/brightness; cat $interface/max_brightness; done

@JeremyB I can't make and edit file in this root folder. I tried to make a file to desktop and copy the fie there but it doesn't happen. And here I give you the answer from the last sentence
/sys/class/backlight/acpi_video0
10
100
/sys/class/backlight/intel_backlight
7812
7812

are the results.

@austin - i tried but when i give the password nothing hapens...

So does

Code: Select all

echo 5000 | sudo tee /sys/class/backlight/intel_backlight/brightness

reduce the brightness?

Thank you very much for the code @JeremyB! I will look like Profi while typing this code! Linux Mint forever

Change the number if you want to suit your needs, 7812 is the max and 0 is a black screen, 1000 might make things hard to read. Once you find what you like you can

Code: Select all

sudo gedit /etc/rc.local

and just above the line exit 0 enter

Code: Select all

echo 5000 > /sys/class/backlight/intel_backlight/brightness

change 5000 to what you want, save, exit program

Code: Select all

sudo chmod +x /etc/rc.local

to make sure it will work and the brightness should be set at the level you want after a reboot
