Background
My old laptop was bought ten years ago. I had never changed the thermal paste between its CPU and its fan. As a result, it had been getting hot during my online tutorials.

Log of my Ubuntu Tweak config
Problem
The touchpad on my new Ubuntu 18.04 LTS laptop was frozen. Toogling 🖱 with
<Fn>-<F4>
didn’t worked.
Attempt
- Logout: didn’t work at all
- Reboot: worked most of the time
Partial solution
After changing the Mouse Click Emulation in Keyboard & Mouse in Ubuntu Tweak from the default “Fingers” (2 fingers for right click; 3 fingers for middle click) to “Area” (Right/middle click determined by clicked area), one might have to wait for next reboot.

Ubuntu installation on hybrid system
Objective
To get a hands-on experience on Ubuntu installation on a UEFI hybrid system.
Devices
- 120 GB SSD disk:
/dev/sda
- 1 TB HDD disk:
/dev/sdb
- 8 GB USB key:
/dev/sdc
Stage 0: precautions
- Ensure that your machine has enough power.
- Disable Secure Boot in M$ Windows
- Disable Quick Boot in boot menu
Stage 1: Make your live USB key
I tried Xubuntu’s built-in disk writing tool to create a live USB key from the official ISO file. Like my Xubuntu 18.04 installation on Fujitsu LH532 , the installer crashed during the installation. After submitting the generated report to Launchpad, I found out that the cause for this crash: the integrity test for my live USB key had failed.

Let's reduce e-waste!
Problem
Two months ago, the Win* 10 installed on my old laptop crashed with
blue screen on startup. Two weeks ago, I created a Xubuntu 18.04
LTS 64-bit Live USB and set up the dualboot. However, the fan
was still giving out consideralbe noise and heat under Xubuntu 18.04
(installed in /dev/sda7
).
Many end users’ reaction
They’ll simply buy a new PC. This had given rise to industrial parks in Guiyu (貴嶼), one of the world’s largest e-waste village. I’m so shocked to see that Hong Kong appears on the top of the linked article.

You may skip to the acutal setup.
Background
After using Win 7 & 10 for six years on my Fujitsu LH532 , Windows 10 often falls into blue screen. Sometimes, it won’t even start up.
Give Xubuntu a try
Hoping to give a second life to my old , I’ve decided to try this popular lightweight distro.
Initial partition setup
I followed the instructions from Danatela’s question, including
the optional setup of separate /var
and /tmp
partition.
