you’ll find lots of people complaining about luks, cryptdevice, grub and a damn usb keyboard… now, the fun comes with new laptops like the one i’m playing with
first of all it has on board a cursed SoC called baytrail (renamed bayFAIL by most of the people on the internet) …. second, well…. whatever… you are on your own … as me, as always
the laptop is a Lenovo 100S, it comes for 199EUR off the shelf in any electronics store in Germany… and to install, go straight to a Debian Testing amd64+i386 DVD iso… to be dd-ed onto a usb stick. Don’t use a non-multiarch installer, the EFI will be ur enemy. It won’t boot 😉
so…. the solution for the damn keyboard… once installed… and once you logged in with an external usb keyboard is to modify the /etc/initramfs-tools/modules and add the following:
i2c_designware_platform
i2c_designware_core
i2c_algo_bit
i2c_hid
then just type:
update-initramfs -u
and reboot
…yes, you are welcome

I tried it on my 100S and it works, Thank you.
my pleasure 😉
did u got the audio working?
yes out of the box with this http://linuxiumcomau.blogspot.com/2017/02/ubuntu-16042-and-updated-ubuntu-1704.html use the 16.04.2 iso and everything works out of the box except of course the battery and the keyboard. to use the keyboard on cryptsetup on startup just follow the steps in here.
sorry, I didn’t notice I was answering to the author, you know better what to do with the keyboard modules 😉 as for the battery I saw something peculiar this evening, the indicator shows the boot time percentage of the battery, and I think it’s pretty accurate, but it needs a restart to refresh it again. With ubuntu 16.04.2 works really nice and smooth. If you are interested you can update also the firmware, from here https://01.org/linuxgraphics/downloads/kabylake-dmc-1.01 it is proprietary but it’s worth it in my opinion.
cool, thanks @Sofos
