[ubuntu] Ubuntu 15.10 - Problem with Intel HD 4000 graphics card driver

Hello all, how are you all doing?

I'm new to GNU/Linux systems . former windows user . and I'm having problems with the graphics driver.
On windows, I could run the screen resolution on 1600x900_60Hz with no problems, but I can't do that now on Ubuntu.

My machine:

Intel i7-3770 Ivy bridge with integrated intel HD 4000 graphics card.

I searched every page, site, and I read every article on the web but couldn't find the solution. My screen stuck on 1024x768(4:3).

I found some solutions, but it wasn't permanent, here's some of them:

Code:

$ cvt 1600 900 60

# 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz
Modeline "1600x900_60.00"  118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync

Then:

Code:

$ xrandr --newmode "1600x900_60.00"  118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync
$

$ xrandr --addmode VGA1 1600x900_60.00

And after typing this:

Code:

 $ xrandr --output VGA1 --mode 1600x900_60.00

the resolution changes to 1600x900, but as soon as I logout/restart the computer it restores the default (1027x768).

Any solution to this problem?
