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 1024x768 in the resolutions menu options. With xrandr i can set a max resolution of 1280x720, but with 1920x1080 the resolution breaks.(Booting in windows i can set 1920x1080 and bigger resolutions).

this is my xorg.0.log. I think there are some mistakes, but I do not know how to resolve them: http://pastebin.com/raw/pujD1hUw

I would greatly appreciate the help. Regards!

  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.
