Back Up the Previous Distro

I did not back up the entire system. I only archived the home directory and copied it out.

shell

# archive the home directory
sudo tar -cf /tmp/home_xxx.tar /home/xxx
# open another terminal and monitor the size while the archive is being created
watch -n 1 ls -lh /tmp/home_xxx.tar

System Configuration

shell

# edit the faillock configuration file
$ sudo nano /etc/security/faillock.conf

# if the number of failed attempts within this interval exceeds deny, the account is locked
fail_interval = 900
# allowed consecutive password failures within fail_interval
deny = 10
# automatic unlock time after the account is locked; set to 0 or never for manual unlock only
unlock_time = 30

Pacman Mirror Selection

If you selected the time zone and language during installation, the top of /etc/pacman.d/mirrorlist usually includes a Country : China mirror by default.

Pacman Configuration

shell

# edit the Pacman configuration file
sudo nano /etc/pacman.conf

Enable colored output: uncomment #Color so it becomes Color.
Adjust parallel downloads: change the value of ParallelDownloads = 4.

Network Time Synchronization

shell

# enable network time sync
sudo timedatectl set-ntp true

# on dual-boot systems with Windows, use local RTC time to avoid an 8-hour offset when switching systems
sudo timedatectl set-local-rtc 1 --adjust-system-clock

# check the status
timedatectl status

`^[[200~` Appears When Pasting Into the Terminal

shell

# temporary fix
$ printf "\e[?2004l"

# permanent fix: append to ~/.zshrc
$ nano ~/.zshrc

# disable Zsh bracketed paste mode
unset zle_bracketed_paste

ArchLinuxCN Repository

shell

# append the ArchLinuxCN repository block to /etc/pacman.conf in commented form
sudo nano /etc/pacman.conf

# [archlinuxcn]

Speed Up AUR GitHub Downloads and `git clone`

Install axel and create a wrapper script for GitHub downloads:

shell

# install axel
$ sudo pacman -S axel
# download the helper script
$ mkdir -p ~/.local/bin
$ curl -fL -o ~/.local/bin/github-mirror-axel.sh https://raw.githubusercontent.com/duanluan/shell-scripts/main/github-mirror-axel.sh
$ chmod +x ~/.local/bin/github-mirror-axel.sh

github-mirror-axel.sh: shell-scripts/github-mirror-axel.sh at main · duanluan/shell-scripts

Edit makepkg.conf:

shell

# copy the default file into the home directory so pacman updates do not overwrite it
cp /etc/makepkg.conf ~/.makepkg.conf

# edit ~/.makepkg.conf
nano ~/.makepkg.conf

# find DLAGENTS and change it to:
DLAGENTS=('file::/usr/bin/curl -qgC - -o %o %u'
          #'ftp::/usr/bin/curl -qgfC - --ftp-pasv --retry 3 --retry-delay 3 -o %o %u'
          #'http::/usr/bin/curl -qgb "" -fLC - --retry 3 --retry-delay 3 -o %o %u'
          #'https::/usr/bin/curl -qgb "" -fLC - --retry 3 --retry-delay 3 -o %o %u'
          'ftp::/usr/bin/axel -n 10 -a -o %o %u'
          'http::/usr/bin/axel -n 10 -a -o %o %u'
          "https::$HOME/.local/bin/github-mirror-axel.sh %o %u"
          'rsync::/usr/bin/rsync --no-motd -z %u %o'
          'scp::/usr/bin/scp -C %u %o')

If you see No state file, cannot resume download!, it usually means curl partially downloaded the file earlier and axel is trying to resume it.

Clear the cache and download again, for example:

shell

rm -rf ~/.cache/paru/clone/geekbench
paru -S geekbench

Example showing that the GitHub download wrapper is working:

shell

$ paru -S clash-verge-rev-bin

Set up URL rewriting to speed up git clone from GitHub:

shell

# remove old rules if you configured them before
git config --global --unset-all url."https://download.fastgit.org/https://github.com/".insteadof
# add the new rule
git config --global url."https://gh-proxy.com/https://github.com/".insteadof "https://github.com/"
# inspect all configured rules
git config --global --get-regexp url

Create a Virtual Display (Must Read for Remote Access)

When connecting remotely, if no monitor is attached locally or the monitor is powered off, the session can fail to connect or show a black screen. Forcing a virtual display solves this.

Open-Source Drivers (Intel / AMD)

Use a kernel parameter to force a virtual output.

shell

# list the current display connectors detected by the system
$ ls /sys/class/drm/

# list connector status and choose one that is disconnected
$ grep "^" /sys/class/drm/*/status

NVIDIA Proprietary Driver (X11)

With the NVIDIA proprietary driver, GRUB injection does not work. You need to modify the Xorg config and create a real-display + virtual-display setup.

shell

# get the GPU PCI address and derive the BusID
$ lspci | grep -i vga

# note 01:00.0; convert it to decimal notation PCI:1:0:0 in the config

Fix a Physical Monitor That Stays Black After Power Cycling or Resume

If the physical monitor stays black after being powered back on, or after resume, while remote access still works, the GPU probably failed to renegotiate the display signal. Add a script that force-resets the output.

shell

# create the reset script
$ mkdir -p ~/.local/bin
$ nano ~/.local/bin/reset_screen.sh

#!/bin/bash
# 1. force-disable the physical display output; replace HDMI-0 with your connector
xrandr --output HDMI-0 --off
# wait a second so the hardware state fully settles
sleep 1
# 2. turn it back on and make it the primary display
# --auto restores the preferred resolution
# --primary makes sure the taskbar returns
# do not specify a relative position; let KDE restore the previous layout automatically
xrandr --output HDMI-0 --auto --primary

# save and make it executable
$ chmod +x ~/.local/bin/reset_screen.sh

Search for Shortcuts from the launcher, go to Add New -> Command or Script, and set the command to ~/.local/bin/reset_screen.sh.

Click Add on the right, assign the shortcut Meta F10, then click Apply.

After turning the monitor back on, press Meta F10 and wait a few seconds.

Problem: global shortcuts do not work while the screen is locked.

Recovery

If the system can no longer enter the graphical session after rebooting, log in via SSH or switch to a TTY with Ctrl Alt F2 and run:

shell

# restore the GRUB config
sudo nano /etc/default/grub
# remove the video=connector:resolution@refresh-rate fragment
# regenerate GRUB
sudo grub-mkconfig -o /boot/grub/grub.cfg

# remove the custom Xorg config
sudo mv /etc/X11/xorg.conf.d/20-nvidia-headless.conf /etc/X11/xorg.conf.d/20-nvidia-headless.conf.bak
# restore the auto-generated config
sudo mv /etc/X11/xorg.conf.d/90-mhwd.conf.bak /etc/X11/xorg.conf.d/90-mhwd.conf
# restore the dummy driver config if it exists
sudo mv /etc/X11/xorg.conf.d/10-headless.conf.bak /etc/X11/xorg.conf.d/10-headless.conf

# reboot
sudo reboot

Increase the X11 Client Limit

This fixes Maximum number of clients reached when launching new graphical applications.

shell

$ sudo pacman -S lsof
# show the top 10 processes using the most X11 connections
$ sudo lsof -U | grep X11-unix | awk '{print $1}' | sort | uniq -c | sort -nr | head -n 10

lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc
      Output information may be incomplete.
lsof: WARNING: can't stat() fuse.cherry-studio.AppImage file system /tmp/.mount_cherryJWuJUB
Output information may be incomplete.

# raise the X11 client connection limit
$ sudo nano /etc/sddm.conf.d/x11-clients.conf

# X11 maximum client limit
