+===== Installing Debian Linux =====
+In short, starting from a plain **Debian 8 Jessie**, we needed the following extra packages:
+  * **linux-image-4.6.0** (from jessie-backports)
+  * **linux-base_4.3** (from jessie-backports)
+  * **firmware-realtek** (from jessie-backports)
+  * **firmware-misc-nonfree** (from jessie-backports)
+  * **firmware-atheros** (from Debian Stretch)
+  * **xserver-xorg-video-intel** (from jessie-backports or pinning from Debian Stretch)
+  * **libgl1-mesa-dri** (from jessie-backports)
+==== Firmwares ====
+This is the list of non-free firmwares needed by the hardware:
+  * **skl_dmc_ver1.bin** (provided by ''firmware-misc-nonfree''), required for graphics card power management.
+  * **rtl8168h-2.fw** (provided by ''firmware-realtek''), required by the Ethernet controller.
+  * **AthrBT_0x31010100.dfu** (provided by ''firmware-atheros''), this is the Bluetooth firmware.
+==== Intel HD Graphics 510, X.org and 3D acceleration ====
+We installed **Debian 8 Jessie**, but found that kernel linux-image-3.16.0 does not handle the Intel **High Definition Graphics 510 GPU**. At boot time no Intel framebuffer is detected and text console is just 80x25 chars. So we installed **linux-image-4.6.0** from jessie-backports, now the kernel detects the GPU and text console is now at high resolution:
+<code>
+[drm] Initialized i915 1.6.0 20160229 for 0000:00:02.0 on minor 0
+i915 0000:00:02.0: fb0: inteldrmfb frame buffer device
+</code>
+X.org does not recognize the Intel card and uses a generic Vesa driver; forcing the **''/etc/X11/xorg.conf''** file in this way:
+<file>
+Section "Device"
+    Identifier  "device1"
+    Driver      "intel"
+EndSection
+</file>
+no devices are detected and X server does not start at all. The error in ''/var/log/Xorg.0.log'' is:
+<code>
+[  8879.997] (II) intel: Driver for Intel(R) Integrated Graphics Chipsets:

+        HD Graphics 4400, HD Graphics 4200, Iris(TM) Pro Graphics 5200
+[  8880.003] (EE) No devices detected.
+</code>
+The problem is with **xserver-xorg-video-intel** package: Jessie has the old 2.21.15 version. We need instead the newer **2.99.917** version from jessie-backports or pinning it from Debian Stretch (testing).
+Finally we needed a newer Mesa library for 3D acceleration. Starting a 3D-aware program with Jessie library will bring the error:
+<code>
+pci id for fd 50: 8086:1902, driver (null)
+i965_dri.so does not support the 0x1902 PCI ID.
+</code>
+Just download and install the package **libgl1-mesa-dri** version **11.1.3** form jessie-backports, which will replace the 10.3.2 version.
