Installing Lubuntu on table-pc Positivo DUO ZX3020

Hi guys,

I've a pc-table (two-in-one, Brazilian branch) with Win10 and I tried to install Ubuntu (preferred Lubuntu) once but found it really difficult. I found a link on the web (caot find it anymore) with a LiveCD that I could boot but the wireless neither the touchscreen were working. I did a search on Brazilian website but no one knew how to get rid of Win10. Considering the new Ubuntu flavor 16.04 (and that Win10 is astonishing slow) I'd like to get help from you guys to see if there is a way to install Lubuntu and use the touchscreen.

Details of the tablet-pc:
Positivo DUO ZX3020
Processor: Intel(R) Atom(TM) CPU Z3735G @ 1.33 GHz - 64bits
RAM: 1 GB
HD: 16 GB
Wireless card: RTL8723BS Wireless LAN 802.11n SDIO
Touchscreen compatible with HID I2C (only information I found)
Kionix KXTJ9 3-axis accelerometer

Thank you,
Hugo
