Fujitsu LH532 Thermal Paste Application

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.

Insensitive Laptop Touchpad

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

  1. Logout: didn’t work at all
  2. 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 18.04 Installation on Fujitsu AH557

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

Fujitsu LH532 Fan Cleaning

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.
