Problem
One can use xrandr to adjust screen brightness. However, the
factor (default to 1.0) is relative to the current brightness.
How to enable the brightness adjust keys / on the keyboard under Xubuntu 18.04?
Solution
Toz’s post on Ubuntu Forum works like a charm. The default value
for GRUB_CMDLINE_LINUX is an empty string. Changing it to
acpi_backlight=vendor and updating the GRUB has solved the
problem since the next boot.
What I mean for correctly is that in the ssh folder of the remote
dotfiles repo, there is neither SSH key files nor entries
representing SSH keys in the gitignore file. You may view
Jan Uhlik’s dotfiles on GitLab as an example.

Rationale
My Linux Mint 18.3 installed on Clevo N240GU was a long-term support (LTS) version.
Although the official pagedidn’t recommend an upgrade for its
own sake, I still performed it as a result of my conversation with a
technician in a computer store. He thought that the display problem
in the current version would be fixed in this upgraded version.
The old version of Linux Mint couldn’t detect the onboard Intel
graphics card. Therefore, sensors reported a higher CPU temperature
and the display resolution couldn’t be correctly configured.

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.

Introduction
Hello World! This is my new GitLab page powered by Hugo. I’m setting
up this blog to practise my math, foreign languages and IT skills.
Why Hugo?
My original goal is to set up a personal blog for posting math.
I used to work with Octopress, but resolving the dependencies and
other technical issues had actually took much more time and effort
than expected. As a result, I digressed a lot from my studies to look
into those problems.
