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.
Reboot
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 upgradeReboot
Download lwfinger wifi driver
sudo apt install git build-essential
mkdir drivers
cd drivers
git clone https://github.com/lwfinger/rtl8723bu.git
cd rtl8723bu
# Remove concurrent mode
nano Makefile
# Find and comment this line: EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
CTRL+x
make
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
CTRL+x
# Reload the new driver
sudo rmmod 8723bu
sudo modprobe -v 8723bu
# Check that the correct driver is in use
