Below are instructions, on how I managed to install Linux Debian onto a Chinese Intel Baytrail based tablet Teclast X80HD.

Reading other related instructions, I have reasons to believe, that also other Baytrail based devices might work using these instructions, as it seem many of them use same HW basis.

In any case I suggest one tries to get as much info about the HW by using HW diagnostics program like Speccy in one's existing Windows installation, for potential deviations from below instructions due to HW differences.

1. Preparing for installation:

- from URL http://cdimage.debian.org/debian-cd/8.3.0/i386/iso-dvd/debian-8.3.0-i386-DVD-1.iso download installation iso file (you can also try newer versions of course)

- write this image file onto FAT formatted USB stick with "unetbootin" program

- plug into your tablet additionally powered USB HUB with USB OTG cable

- plug into USB HUB mouse, keyboard, Installation USB stick and prefferably also USB Wifi stick, that is natively supported by Debian; see https://wiki.debian.org/WiFi

2. Installation:

- power on tablet with attached USB HUB

- make sure to boot from attached USB stick by entering BIOS/EFI (in my case pressing ESC key at BIOS/EFI listing) and use Boot Override to boot from USB installation stick

- in boot menu select install or graphical install and press e

- at the end of the line starting with "linux /boot" (line might be wrapped around in another line) add following " nomodeset" (make sure to add space between end of line and nomodeset)

- press CTRL+x or F10

- follow instructions until the end

3. Basics:

Other references are on https://packages.debian.org/stable/ .

- disable Screensaver

- disable System Sleep Mode and Display Power Management in Power Options

- plug in USB wifi supported by debian or download driver for your USB stick and install it with command "dpgk -i driver_file.deb"

- in syncaptic package manager > settings > repositories modify repositories to:

deb http://ftp.debian.org/debian/ jessie main contrib non-free

deb-src http://ftp.debian.org/debian/ jessie main contrib non-free

- upgrade all packages with:

su

apt-get update

apt-get upgrade

4. Upgrade kernel:

Instructions are taken from http://www.pcsteps.com/858-kernel-upgrade-linux-mint-ubuntu/ .

For other versions of the kernel check http://kernel.ubuntu.com/~kernel-ppa/mainline/ .

su

uname -r #current kernel version

apt-get install build-essential linux-headers-686-pae

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400-generic_4.4.0-040400.201601101930_i386.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400_4.4.0-040400.201601101930_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-image-4.4.0-040400-generic_4.4.0-040400.201601101930_i386.deb

dpkg -i linux-headers-4*.deb linux-image-4*.deb

reboot

uname -r #current kernel version

5. Install drivers for internal Wifi chip:

I'm assuming you have the same Wifi chip which is Realtek RTL8723BS (check Speccy report).

su

apt-get install git

cd /usr/local/src

wget https://github.com/hadess/rtl8723bs/archive/master.zip

unzip master

cd rtl8723bs-xxx

make

mkdir /lib/firmware/rtlwifi

make install

depmod -a

modprobe r8723bs

Instructions are taken from https://github.com/hadess/rtl8723bs/wiki/RTL8723BS-module-building-instruction-for-Debian-GNU-Linux .

6. Most probably touch screen sensor should work after updating kernel to 4.4 or later. In case touchscreen isn't working and it's Goodix based (check Speccy report) you can try installing drivers manually:

su

cd /usr/local/src

git clone https://github.com/hadess/gt9xx.git

cd gt9xx

make

make install

depmod -a

modprobe goodix_backport

7. For touchscreen to work, as more than simple mouse replacement, you need to install package "touchegg" in following way:

su

apt-get install build-essential libqt4-dev libgeis-dev libx11-6 libxtst-dev

cd /usr/local/src

git clone https://github.com/JoseExposito/touchegg.git

cd touchegg

qmake

make

make install

Instructions are taken from https://github.com/JoseExposito/touchegg/wiki/How-to-compile-Touch%C3%A9gg-source-code .

Other references are https://www.linux.com/learn/tutorials/799669-how-to-configure-a-touchscreen-on-linux .

Then you probably need to further configure touchegg, with usefull instructions on https://wiki.archlinux.org/index.php/touchegg according to your needs.

8. For typing virtual keyboard is needed, I recommend "florence" package:

su

apt-get install florence

That's as far as I got. Probably now you should have display, touchscreen and Wifi working. I couldn't yet enable sound, as well as power management.

In any case, you might want to check other instructions and distributions, like Linuxium, Fedlet, T100 (which none worked for me) and below links (none worked for me):

Good luck. Eventually I installed Windows on the tablet, but might try in a year, if future Linux distros will better support these tablets.
