Using WSL 2 with X-Server — Linux on Windows

What is WSL 2

The Windows Subsystem for Linux lets developers run a GNU/Linux environment — including most command-line tools, utilities, and applications — directly on Windows, unmodified, without the overhead of a traditional virtual machine or dualboot setup.

Install WSL2 on Windows 10

Using the following link here install the WSL 2 on your Windows 10. The Microsoft tutorial is very simple and clean.

How I Switched from Windows 10 to Linux Mint

This article is all about my journey on switching from Windows 10 to Linux Mint 20, how I got easily adapted to the Linux environment, and some resources that helped me to set up a perfect Desktop environment.

Uncertainty

Ok, now I have decided to switch to Linux but here comes the first question. Which distro will satisfy my needs both in terms of GUI and other aspects? Linux is not something new to me since I have been working with RHEL based distros in my work for the past 4 years with the command-line.

I know RHEL based distros are good for enterprises but not for personalized desktop environments, at least that’s what I am thinking till now. So I started my research to find the distro that should be easy for me to use and at the same time should have good community support if in case I ran into some problem. Among many Linux distros, I drilled down my list to 4 flavors.

Related ArticleThe Best Linux Distributions for Beginners

Before deciding the Distro it is necessary you formulate the list of tools/programs or packages needed and check if the distro you choose provides all those features.

For me, I use Linux for two main purposes: one is for my professional development work, writing articles, and second for my personal use like Video editing and Movies. Most of the popular software are created to be compatible with Windows, macOS, and Linux like Sublime TextVSCodeVLC Media PlayerFirefox/Chromium browser. Other than these software, cloud-based services make our life easy Like Microsoft Office 365 or G Suite.

Using WSL 2 to develop Java application on Windows

As a Java developer, If you want to set up a development environment on Windows you have three options (my experiences):

  • Download native JDK, Maven, and … for Windows and install them directly on the Windows.
  • Install A desktop Linux distro on the VMWare or Virtualbox and then install JDK, Maven, and … on that VM.
  • Install an Ubuntu server using Multipass and then connect to it using **RDP **(if you installed a desktop environment on the Ubuntu server) or connect to it using an X Server like VcXsrv.

The first option is the most straightforward one but it won’t work always if you need some specific Linux features in your development process. The second and third options are good for having Linux features but they don’t have good performance and consume a lot of resources.

In this article, I am going to introduce a fourth option (using WSL 2 and X Server) and compare its performance with the first option.

What is WSL 2

WSL 2 is completely revamped and now we have a complete Linux kernel built by Microsoft (WSL2-Linux-Kernel) that runs in a lightweight utility VM (virtual machine). The virtualization technology in WSL 2 does not look like a traditional VM (slow to boot, isolated, consumes lots of resources and …), it is managed and run behind the scenes without any configurations.

You can know more about WSL 2 architecture in this video:

📺 Demo

🔩 Basic Demo

// FButton #1
FButton(
  height: 40,
  alignment: Alignment.center,
  text: "FButton #1",
  style: TextStyle(color: Colors.white),
  color: Color(0xffffab91),
  onPressed: () {},
)

// FButton #2
FButton(
  padding: const EdgeInsets.fromLTRB(12, 8, 12, 8),
  text: "FButton #2",
  style: TextStyle(color: Colors.white),
  color: Color(0xffffab91),
  corner: FCorner.all(6.0),
)

// FButton #3
FButton(
  padding: const EdgeInsets.fromLTRB(12, 8, 12, 8),
  text: "FButton #3",
  style: TextStyle(color: Colors.white),
  disableStyle: TextStyle(color: Colors.black38),
  color: Color(0xffF8AD36),

  /// set disable Color
  disabledColor: Colors.grey[300],
  corner: FCorner.all(6.0),
)

By simply configuring text andonPressed, you can construct an available FButton.

If onPressed is not set, FButton will be automatically recognized as not unavailable. At this time, ** FButton ** will have a default unavailable status style.

You can also freely configure the style of FButton when it is not available via the disabledXXX attribute.

🎈 Corner & Stroke

// #1
FButton(
  width: 130,
  text: "FButton #1",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFF7043),
  onPressed: () {},
  clickEffect: true,
  
  /// 配置边角大小
  ///
  /// set corner size
  corner: FCorner.all(25),
),

// #2
FButton(
  width: 130,
  text: "FButton #2",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFFA726),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner(
    leftBottomCorner: 40,
    leftTopCorner: 6,
    rightTopCorner: 40,
    rightBottomCorner: 6,
  ),
),

// #3
FButton(
  width: 130,
  text: "FButton #3",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFFc900),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner(leftTopCorner: 10),
  
  /// 设置边角风格
  ///
  /// set corner style
  cornerStyle: FCornerStyle.bevel,
  strokeWidth: 0.5,
  strokeColor: Color(0xffF9A825),
),

// #4
FButton(
  width: 130,
  padding: EdgeInsets.fromLTRB(6, 16, 30, 16),
  text: "FButton #4",
  style: TextStyle(color: Colors.white),
  color: Color(0xff00B0FF),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner(
      rightTopCorner: 25,
      rightBottomCorner: 25),
  cornerStyle: FCornerStyle.bevel,
  strokeWidth: 0.5,
  strokeColor: Color(0xff000000),
),

You can add rounded corners to FButton via the corner property. You can even control each fillet individually。

By default, the corners of FButton are rounded. By setting cornerStyle: FCornerStyle.bevel, you can get a bevel effect.

FButton supports control borders, provided that strokeWidth> 0 can get the effect 🥳.

🌈 Gradient


FButton(
  width: 100,
  height: 60,
  text: "#1",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFFc900),
  
  /// 配置渐变色
  ///
  /// set gradient
  gradient: LinearGradient(colors: [
    Color(0xff00B0FF),
    Color(0xffFFc900),
  ]),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner.all(8),
)

Through the gradient attribute, you can build FButton with gradient colors. You can freely build many types of gradient colors.

🍭 Icon

FButton(
  width: 88,
  height: 38,
  padding: EdgeInsets.all(0),
  text: "Back",
  style: TextStyle(color: Colors.white),
  color: Color(0xffffc900),
  onPressed: () {
    toast(context, "Back!");
  },
  clickEffect: true,
  corner: FCorner(
    leftTopCorner: 25,
    leftBottomCorner: 25,),
  
  /// 配置图标
  /// 
  /// set icon
  image: Icon(
    Icons.arrow_back_ios,
    color: Colors.white,
    size: 12,
  ),

  /// 配置图标与文字的间距
  ///
  /// Configure the spacing between icon and text
  imageMargin: 8,
),

FButton(
  onPressed: () {},
  image: Icon(
    Icons.print,
    color: Colors.grey,
  ),
  imageMargin: 8,

  /// 配置图标与文字相对位置
  ///
  /// Configure the relative position of icons and text
  imageAlignment: ImageAlignment.top,
  text: "Print",
  style: TextStyle(color: textColor),
  color: Colors.transparent,
),

The image property can set an image for FButton and you can adjust the position of the image relative to the text, throughimageAlignment.

If the button does not need a background, just set color: Colors.transparent.

🔥 Effect


FButton(
  width: 200,
  text: "Try Me!",
  style: TextStyle(color: textColor),
  color: Color(0xffffc900),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner.all(9),
  
  /// 配置按下时颜色
  ///
  /// set pressed color
  highlightColor: Color(0xffE65100).withOpacity(0.20),
  
  /// 配置 hover 状态时颜色
  ///
  /// set hover color
  hoverColor: Colors.redAccent.withOpacity(0.16),
),

The highlight color of FButton can be configured through the highlightColor property。

hoverColor can configure the color when the mouse moves to the range of FButton, which will be used during Web development.

🔆 Loading

FButton(
  text: "Click top loading",
  style: TextStyle(color: textColor),
  color: Color(0xffffc900),
  ...

  /// 配置 loading 大小
  /// 
  /// set loading size
  loadingSize: 15,

  /// 配置 loading 与文本的间距
  ///
  // Configure the spacing between loading and text
  imageMargin: 6,
  
  /// 配置 loading 的宽
  ///
  /// set loading width
  loadingStrokeWidth: 2,

  /// 是否支持点击自动开始 loading
  /// 
  /// Whether to support automatic loading by clicking
  clickLoading: true,

  /// 配置 loading 的颜色
  ///
  /// set loading color
  loadingColor: Colors.white,

  /// 配置 loading 状态时的文本
  /// 
  /// set loading text
  loadingText: "Loading...",

  /// 配置 loading 与文本的相对位置
  ///
  /// Configure the relative position of loading and text
  imageAlignment: ImageAlignment.top,
),

// #2
FButton(
  width: 170,
  height: 70,
  text: "Click to loading",
  style: TextStyle(color: textColor),
  color: Color(0xffffc900),
  onPressed: () { },
  ...
  imageMargin: 8,
  loadingSize: 15,
  loadingStrokeWidth: 2,
  clickLoading: true,
  loadingColor: Colors.white,
  loadingText: "Loading...",

  /// loading 时隐藏文本
  ///
  /// Hide text when loading
  hideTextOnLoading: true,
)


FButton(
  width: 170,
  height: 70,
  alignment: Alignment.center,
  text: "Click to loading",
  style: TextStyle(color: Colors.white),
  color: Color(0xff90caf9),
  ...
  imageMargin: 8,
  clickLoading: true,
  hideTextOnLoading: true,

  /// 配置自定义 loading 样式
  ///
  /// Configure custom loading style
  loadingWidget: CupertinoActivityIndicator(),
),

Through the loading attribute, you can configure Loading effects for ** FButton **.

When FButton is in Loading state, FButton will enter an unavailable state, onPress will no longer be triggered, and unavailable styles will also be applied.

At the same time loadingText will overwritetext if it is not null.

The click start Loading effect can be achieved through the clickLoading attribute.

The position of loading will be affected by theimageAlignment attribute.

When hideTextOnLoading: true, if FButton is inloading state, its text will be hidden.

Through loadingWidget, developers can set completely customized loading styles.

Shadow


FButton(
  width: 200,
  text: "Shadow",
  textColor: Colors.white,
  color: Color(0xffffc900),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner.all(28),
  
  /// 配置阴影颜色
  ///
  /// set shadow color
  shadowColor: Colors.black87,

  /// 设置组件高斯与阴影形状卷积的标准偏差。
  /// 
  /// Sets the standard deviation of the component's Gaussian convolution with the shadow shape.
  shadowBlur: _shadowBlur,
),

FButton allows you to configure the color, size, and position of the shadow.

🍭 Neumorphism Style

FButton(

  /// 开启 Neumorphism 支持
  ///
  /// Turn on Neumorphism support
  isSupportNeumorphism: true,

  /// 配置光源方向
  ///
  /// Configure light source direction
  lightOrientation: lightOrientation,

  /// 配置亮部阴影
  ///
  /// Configure highlight shadow
  highlightShadowColor: Colors.white,

  /// 配置暗部阴影
  ///
  /// Configure dark shadows
  shadowColor: mainShadowColor,
  strokeColor: mainBackgroundColor,
  strokeWidth: 3.0,
  width: 190,
  height: 60,
  text: "FWidget",
  style: TextStyle(
      color: mainTextTitleColor, fontSize: neumorphismSize_2_2),
  alignment: Alignment.center,
  color: mainBackgroundColor,
  ...
)

FButton brings an incredible, ultra-high texture Neumorphism style to developers.

Developers only need to configure the isSupportNeumorphism parameter to enable and disable the Neumorphism style.

If you want to adjust the style of Neumorphism, you can make subtle adjustments through several attributes related to Shadow, among which:

shadowColor: configure the shadow of the shadow

highlightShadowColor: configure highlight shadow

FButton also provides lightOrientation parameters, and even allows developers to adjust the care angle, and has obtained different Neumorphism effects.
