Xrandr: Failed to get size of gamma for output default

No matter what I do, both of my monitors show exactly the same content I tried all combinations of the 3 ports, none of them allows me to turn my two displays to an extended desktop, similar to twinview for nvidia. The mobo is Gigabyte HD-Z87-HD3, which has 1 DVI, 1 HDMI and 1 VGA output. My graphics uses the build-in graphics from my newly purchased i7 4770 (I believe it is Intel HD 4600). I am having difficulty configuring dual-screen on my Ubuntu (12.04 LTS) box. As someone who solely uses Linux for work and play, I'd like to know if HD 4000 is available for the desktop? My laptop also has an nVidia 650m, but I haven't even bothered installed the latest Bumblebee (3.0) in order to use the 650m as I'm so happy with the HD 4000. I've also found that QuakeLive does not start (with or without SNA). It's nothing major, but for me it's annoying. The bug I discovered is the titlebar is not rendered correctly on some windows that lose focus (Firefox being one of them). If there is output from the above command, then SNA is running. You can check that SNA is running by opening up a terminal and entering the following: To enable SNA, you have to modify or create /etc/X11/nf, and add the following:Īfter doing this, reboot. Having said that, SNA is not enabled by default. I have discovered, however, that SNA ( SandyBridge New Acceleration) is still buggy on Linux (I've only tried with Ubuntu 12.10).

Dual monitor support works flawlessly (unlike dual monitor support with the proprietary nVidia drivers which always resulted in tearing in one of the monitors because it wasn't able to vsync two different monitors correctly).

The installation was painless (non-existent - just installed by default). Everything is so snappy, smooth and responsive. It's my first experience with Intel graphics, and I have to say I'm extremely impressed.

The Intel drivers were installed during the OS installation process without having to do anything. I just installed Ubuntu 12.10 on a Samsung NP700Z7C-S02UK.
