Installing Xubuntu on Ezbook S3

After a few experiments I decided to make full disk xubuntu installation.

I bought a cheap laptop from china: Ezbook 3S.

After a few tests with live linux and a few installation on external devices I decided to wipe windows and use Xubuntu.

I started with a respin iso.

I made a full disk installation with full disk encryption and LVM.


Change the DPI to 110 in Settings -> Appearance -> Fonts. Change the default xfce theme in Settings -> Window Manager -> Style to Numix

Install the updates and reboot.

There is also a kernel upgrade so it will take a bit

sudo apt update && sudo apt get upgrade


Download lwfinger wifi driver

sudo apt install git build-essential
mkdir drivers
cd drivers
git clone
cd rtl8723bu
# Remove concurrent mode
nano Makefile
# Find and comment this line: EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
sudo make install
sudo modprobe -v 8723bu
# blacklist the old driver
nano /etc/modprobe.d/blacklist.conf
# Add the following two lines at the end of the file
# Driver replaced by 8723bu by lwfinger
blacklist rtl8xxxu
# Reload the new driver
sudo rmmod 8723bu
sudo modprobe -v 8723bu
# Check that the correct driver is in use
