Brightness on Inspiron 13z or 1370 with Mint 17
I am a new user of Linux Mint.
I have got a Dell Inspiron 13z (or 1370), before I was using it on Ubuntu 14.04 but for some reasons, I had to change it to Linux Mint 17. I install it, everything is running except the brightness... which was also a problem on Ubuntu 14.04 and previous versions, but through this solution, it is possible to solve it.
On my new installation (Mint 17), I tried this solution, but it didn't solve the problem. Does anyone have got a solution, or an idea to test it?
Is it better to use Nvidia drivers or the Xorg drivers?
Regards

What was the solution in Ubuntu 14.04? It should work in LM 17 too, as long as it is the same kernel version- Ubuntu will update the kernel through update manager but LM 17 will notOni45 wrote:Dear all,

I use this method (see into the pdf document which is in the message): https://bugs.launchpad.net/ubuntu/+sour ... omments/16
Yes, I was thinking exactly the same, as it is based on the same base! It works fine on XUbuntu 14.04 32 bits but not with LM17 64 bits. I tried it alone, in double boot etc. but nothing change.

It shows what to put in a file that might get backlight working with nvidia

I tried one, but when I save in Gedit, it says that "it is impossible to save the file" and propose to check the path and to try again.
Have you got a command line to advice (I am not expert in Linux).

It says that nvidia drivers 304.116 and 304.121 allow the backlight to work

In my driver manager, I have got these drivers:JeremyB wrote:According to a bug report https://bugs.launchpad.net/ubuntu/+sour ... ug/1241745

- nvidia-331 (recommanded) - Version 331.38-0ubuntu7
nvidia-331-updates - Version 331.38-0ubuntu7
nvidia-304-updates - Version 304.117-0ubuntu1
xserver-xorg-video-nouveau
nvidia-304 - Version 304.117-0ubuntu1
Then I found this link: http://ubuntuhandbook.org/index.php/201 ... cy-ubuntu/
but when I do Ctrl+Alt+F1 nothing happen (I think it is because the F1 button need to press the Fn button).
When I enter this command:

sudo service mdm stop
It become crazy with this problem... I think I will leave LMint with this computer and stay with XUbuntu.
