I received my Defiance II laptop a couple of days ago, and I love it (a big "THANK YOU" to the team at PC Specialist). The screen, the keyboard, the performance - everything is exactly what I was looking for (and then some!). I'm primarily using it for a side-project that involves a lot of virtual machines and containers, so I was looking for a powerful laptop with at least 32GB of RAM. The Defiance II delivers.
Installing Ubuntu 15.10
The laptop came with an un-activated version of Windows 10 that PC Specialist used as part of their quality assurance process. This isn't a big deal. I have installed Ubuntu 15.10 as the sole operating system, but these instructions should also work if you wish to dual-boot (just select the correct option during the installation).
Installing the nVidia Drivers
I have not yet been successful in downloading and installing the nVidia proprietary binaries directly from the nVidia website (I tried blacklisting the Nouveau drivers, but this didn't work. I didn't try completely uninstalling the Nouveau drivers). This isn't a big deal though, as the "Additional Drivers" applet will install the nVidia drivers for you:
Upgrading the Kernel
Some of the new Skylake features can only be used with a 4.4 (or higher) kernel. To install the 4.4.1 kernel:
Switching to Hybrid Graphics
After upgrading the kernel, you can now go in to the BIOS and switch back to MSHYBRID graphics, and the system will not randomly freeze up after 30 seconds (as it does on the 3.19 kernel). The battery will also last twice as long (around 4 hours, depending on what you're doing). However, certain things do not work when in Hybrid Graphics mode:

- Go in to your BIOS by pressing the F2 key repeatedly when you see the PC Specialist logo appear.
- Under Advanced | Advanced Chipset Control, set MSHYBRID or DISCRETE SWITCH to DISCRETE (very important!).
- Under Security, set Secure Boot to Disabled.
- Insert your bootable flash drive (containing the Ubuntu 15.10 installation media) in to one of the USB ports.
- In the BIOS, go to EXIT and select Save Changes and Reset.
- This time, when you see the PC Specialist logo, press F7 repeatedly - a menu should appear allowing you to select your boot device.
- From the boot menu, select your flash drive (which should be listed).
- Follow the installation instructions (choose the options you wish, I won't go in to these here).
- Once the installation is complete, you will be prompted to reboot.
Installing the nVidia Drivers
I have not yet been successful in downloading and installing the nVidia proprietary binaries directly from the nVidia website (I tried blacklisting the Nouveau drivers, but this didn't work. I didn't try completely uninstalling the Nouveau drivers). This isn't a big deal though, as the "Additional Drivers" applet will install the nVidia drivers for you:
- Click on the Unity Dash (the icon at the very top of the left-hand menu).
- In the search box, type in "Additional" (without the quotes) - you should see Additional Drivers appear in the search results.
- Click on Additional Drivers to open the Additional Drivers applet.
- Under the "NVIDIA Corporation: GM204M [GeForce GTX 9xxM]", select the "Using NVIDIA binary driver - version 352.63 from nvidia-352-updates" (may be different).
- Click on the Apply Changes button.
- You may have to log out and log back in again for the changes to take effect.
Upgrading the Kernel
Some of the new Skylake features can only be used with a 4.4 (or higher) kernel. To install the 4.4.1 kernel:
- Open a terminal and then enter these commands:
-
Code:
mkdir -p /tmp/kernel cd /tmp/kernel wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.1-wily/linux-headers-4.4.1-040401_4.4.1-040401.201601311534_all.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.1-wily/linux-headers-4.4.1-040401-generic_4.4.1-040401.201601311534_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.1-wily/linux-image-4.4.1-040401-generic_4.4.1-040401.201601311534_amd64.deb sudo dpkg -i *.deb

The battery will also last twice as long (around 4 hours, depending on what you're doing). However, certain things do not work when in Hybrid Graphics mode:
- The Fn + Screen Brightness Up/Down keys do not work (you can still adjust screen brightness using System Settings | Brightness and Lock).
- Shutdown does not work (I have tracked this down to LightDM - for some reason it just freezes the system when it's stopped).
- Suspend does not work (again, it's LightDM that's casuing the freeze up).
