Introduction

Remote desktop applications have revolutionized how we access and control computers from distant locations. Among these applications, Google Chrome Remote Desktop stands out due to its ease of use, reliability, and cross-platform support. This guide will walk you through the process of installing Google Chrome Remote Desktop on Ubuntu 24.04. Whether you’re a beginner or a seasoned Linux user, this comprehensive tutorial will ensure you have remote access up and running in no time.

Why Use Google Chrome Remote Desktop?

Before diving into the installation process, it’s crucial to understand why Google Chrome Remote Desktop is a preferred choice for many:

  • Cross-Platform Compatibility: It works seamlessly on Windows, macOS, Linux, and Chrome OS.
  • Security: Uses a secure connection and encryption to protect your data.
  • Free to Use: Unlike many remote desktop solutions, it is completely free.
  • Ease of Use: Simple to set up and use, even for non-technical users.

Prerequisites

To begin with, ensure you have the following:

  1. Google Chrome Browser: Google Chrome Remote Desktop requires the Chrome browser.
  2. Google Account: You’ll need a Google account to use this service.
  3. Terminal Access: Basic knowledge of using the terminal is necessary.

Google Chrome Remote Desktop on Ubuntu 24.04: Step-by-Step Guide

First things first, update your Ubuntu machine:

sudo apt update -y && sudo apt upgrade -y

Step 1: Install Google Chrome

Next, you’ll need to install the Google Chrome browser on your Ubuntu 24.04 system. Open your terminal and follow these commands:

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
wget https://dl.google.com/linux/direct/chrome-remote-desktop_current_amd64.deb
sudo dpkg -i google-chrome-stable_current_amd64.deb
sudo apt-get install -f

The above commands will download and install the latest version of Google Chrome. The -f option in the last command fixes any dependency issues.

Step 2: Install Google Chrome Remote Desktop

Next, you need to add the Chrome Remote Desktop extension to your browser. Open Google Chrome and visit the Chrome Web Store. Search for “Chrome Remote Desktop” and add the extension to your browser.

Alternatively, you can use the following link to directly add the extension: Chrome Remote Desktop Extension.

Step 3: Set Up Remote Desktop on Google Chrome

After installing the extension, follow these steps to set up remote access:

  • Open a new tab in Google Chrome and go to remotedesktop.google.com/access.
  • Click this Download link to download the Debian package for Chrome Remote Desktop.
  • Open your terminal and navigate to the download location. Then, install the package using:
sudo dpkg -i chrome-remote-desktop_current_amd64.deb

Step 4: Enable Remote Desktop Access

To enable remote desktop access, you may need to install and configure a desktop environment if you’re using a server version of Ubuntu without a GUI. Here’s how you can install the Xfce desktop environment:

sudo apt-get install xfce4 xfce4-goodies
sudo apt-get install -f
  • After installation, set Xfce as the default desktop environment for Chrome Remote Desktop:
sudo vim /etc/chrome-remote-desktop-session
  • Replace the content with (then, save and close the file):
exec /usr/sbin/lightdm-session 'xfce4-session'
  • Now reboot your machine:
sudo systemctl reboot

Step 5: Configure Remote Desktop

To configure Chrome Remote Desktop, follow these steps (from another Google Chrome Browser on another machine):

  • Press the Enter key to continue. You’ll be prompted to enter a six-digit PIN. You will need this later to remote to your Ubuntu machine after the installation completes.

Using Google Chrome Remote Desktop

Once the setup is complete, you can access your Ubuntu 24.04 system from any device with the Chrome browser and Chrome Remote Desktop extension installed. Here’s how you can connect:

Open Chrome and navigate to remotedesktop.google.com/access

Troubleshooting Common Issues

Even with the best instructions, issues can arise. Here are some common problems and solutions:

Problem: Unable to Start the Chrome Remote Desktop Service

Solution: Check the status of the service with:

sudo service chrome-remote-desktop start

If the service isn’t active, try restarting it:

sudo systemctl restart chrome-remote-desktop

Problem: Black Screen After Connecting

Solution: This issue often occurs due to a missing or misconfigured desktop environment. Ensure that Xfce is installed correctly and set as the default session in the /etc/chrome-remote-desktop-session file.

Problem: Connection Timeout

Solution: Ensure that your internet connection is stable. You may also need to check your firewall settings to ensure that Chrome Remote Desktop is allowed.

Advantages of Using Google Chrome Remote Desktop

Security

One of the primary concerns with remote desktop applications is security. Chrome Remote Desktop uses a secure SSL connection and requires a PIN to access your system, ensuring that your data remains protected.

Performance

Chrome Remote Desktop offers smooth performance with minimal lag, even over slower internet connections. This makes it an ideal choice for accessing your desktop applications from anywhere.

Conclusion

Google Chrome Remote Desktop is an excellent tool for anyone needing remote access to their Ubuntu 24.04 system. By following this step-by-step guide, you can easily set up and configure remote desktop access, ensuring you have control over your system from anywhere. With its robust security features and seamless performance, it’s a reliable choice for both personal and professional use.

Using GNU awk in windows to get the files size , take times, copy write speed

GNU awk 

https://gnuwin32.sourceforge.net/packages/gawk.htm


透過awk取得 robocopy 檔案大小、操作時間、測試速度

Using awk in windows, get the files size , take times, copy write speed



以下為robocopy_getSpeed.bat

@echo off

setlocal enabledelayedexpansion


:: 檢查是否有傳入速度限制參數

if "%~1"=="" (

    echo 請傳入速度限制（MB/s）作為參數，例如：robocopy_getSpeed.bat 10

    exit /b 99

)


set "limit=%~1"

if "%~2"=="" (

set "logfile=robocopy_log.txt"

) else (

set "logfile=%~2"

)



if not exist "!logfile!" (

    echo [%DATE% %TIME%] !logfile! 不存在

exit /b 3

)


:: 取得 Bytes（MB）

for /f %%A in ('findstr "Bytes[^/]" %logfile% ^| awk "{ print $3 }"') do (

    set "bytes=%%A"

)


:: 取得 Time（秒）支援 HH:MM:SS 或 MM:SS

for /f %%A in ('findstr "Times" %logfile% ^| awk "{ n=split($3,t,\":\"); if (n==3) print t[1]*3600 + t[2]*60 + t[3]; else if (n==2) print t[1]*60 + t[2]; else print 0 }"') do (

    set "seconds=%%A"

)



if "!bytes!"=="" (

exit /b 2

if "!seconds!"=="" (

exit /b 2

)


:: 使用 PowerShell 計算速度（MB/s）

for /f %%S in ('powershell -command "[math]::Round(%bytes% / %seconds%, 2)"') do (

    set "speed=%%S"

)


echo Bytes: %bytes% MB

echo Time: %seconds% 秒

echo 速度: %speed% MB/s

echo 限速: %limit% MB/s


:: 比較速度與限制

powershell -command "if (%speed% -lt %limit%) { exit 2 } else { exit 1 }"
