Ubuntu – I cant get 1920×1080 with Intel Linux Graphic Driver

display-resolutiondriversintel graphicsxorg

have a motherboard with integrated Intel HD 4600 Graphics.
Im running a fresh installed Ubuntu 15.10 with the official driver of Intel Installed: intel linux 01 graphics

But i cant get resolutions higher than 1024×768 in the resolutions menu options.
With xrandr i can set a max resolution of 1280×720, but with 1920×1080 the resolution breaks.(Booting in windows i can set 1920×1080 and bigger resolutions).

this is my xorg.0.log. I think there are some mistakes, but I do not know how to resolve them:

I would greatly appreciate the help.

    1. Temporary solution:

      • Open a terminal and type: cvt 1920 1080 [your refresh rate]

    e.g. cvt 1920 1080 60

    • output of the command likes this:

    Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

    • copy the output line after the Modeline part and add it to xrandr:

      sudo xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
      sudo xrandr --verbose --addmode VGA1 "1920x1080_60.00"
      sudo xrandr --output VGA1 --mode "1920x1080_60.00"
      

    If I see it right in your log you have 3 output: VGA1, HDMI1 and HDMI2. You can change the --output VGA1 with the two HDMI if necessary.

    1. Permanent solution:

      • Edit the /etc/X11/xorg.conf file with root privileges:

    e.g. sudo gedit /etc/X11/xorg.conf

    • Add/edit these parts:

      Section "Monitor"
      Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
      EndSection
      

    and

        Section "Screen"
        SubSection "Display"
        Modes "1920x1080@60"
    

    Restart the system.
