+h5. Building a boot image
+
+You now need to create a valid boot image with your own kernel build.
+
+On your host PC, we need to install the following tools:
+
+bc. sudo apt-get install device-tree-compiler
+git clone git://codeaurora.org/quic/kernel/skales
+
+The boot image consists of the table of device tree (@dt.img@), the kernel image (@Image@) and an init ramdisk image.
+
+The @dtbTool@ is a standalone application that will process the DTBs generated during the kernel build, to create the table of device tree image. This tool is included in the @skales@ git tree cloned above.
+
+bc. ./skales/dtbTool -o dt.img -s 2048 arch/arm64/boot/dts/qcom/
+
+To create the boot image, you also need a ramdisk image, and you can use the one from the release:
+
+bc. wget http://builds.96boards.org/releases/dragonboard410c/linaro/ubuntu/##RELEASE##/initrd.img-##KERNEL_VER##.0-linaro-lt-qcom
 
-You now need to create a valid boot image with your own kernel build. Please refer to this "wiki":https://github.com/96boards/documentation/wiki/Dragonboard-410c-Boot-Image for detailed instructions to create such a boot image.
+The tool @mkbootimg@ (also in the git tree previously cloned) is a standalone application that will process all files and create the boot image that can then be booted on the target board, or flash into the on-board eMMC. The boot image also contains the kernel bootargs, which can be changed as needed in the next command:
+
+bc. ./skales/mkbootimg --kernel arch/arm64/boot/Image \
+                   --ramdisk initrd.img-##KERNEL_VER##.0-linaro-lt-qcom \
+                   --output boot-db410c.img \

 * all associated .deb files will be located in the root folder, and can be installed in the system with dpkg -i <pkg>.deb.
 * all these commands should be executed on the target directly, not on the development host. It is generally enough to build packages natively, on the target platform. For some packages, it is possible to cross compile Ubuntu/Debian packages however this goes beyond the scope of this wiki page. 
 
+h4. Using X11 with modesetting video driver and GLAMOR
+
+While not enabled by default, it is possible use evaluate X11/GLAMOR. In order to start X server with the modesetting driver, with GLAMOR support, your first need to make sure that X server is not running:
+
+bc. sudo systemctl stop lightdm
+
+Then you can run the following commands to switch from freedreno video driver, to modesetting, and restart the LXDE desktop:
+
+bc. sudo sed -i 's/freedreno/modesetting/' /usr/share/X11/xorg.conf.d/42-freedreno.conf
+sudo systemctl start lightdm
+
+To switch back to freedreno video driver, please run:

+bc. sudo systemctl stop lightdm
+sudo sed -i 's/modesetting/freedreno/' /usr/share/X11/xorg.conf.d/42-freedreno.conf
+sudo systemctl start lightdm
