# DRM Start Steps
|
||||
|
||||
[中文](README_CN.md)
|
||||
|
||||
(Ubuntu 20.04 live server linux-x64 Virtual Machine Test Success)
|
||||
(Orange Pi Zero2 Ubuntu20.04-arm64 Test Success)
|
||||
|
||||
[Avalonia Official Reference Document](https://docs.avaloniaui.net/docs/next/guides/platforms/rpi/running-on-raspbian-lite-via-drm)
|
||||
|
||||
## Setup Running Environment
|
||||
|
||||
1. Run the following commands on the Linux side
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt upgrade
|
||||
sudo reboot
|
||||
sudo apt-get install libgbm1 libgl1-mesa-dri libegl1-mesa libinput10
|
||||
```
|
||||
|
||||
2. Install the test tool (if a colored cube appears, the environment is installed)
|
||||
```bash
|
||||
sudo apt-get install kmscube
|
||||
sudo kmscube
|
||||
```
|
||||
|
||||
3. [Install .NET Runtime](https://learn.microsoft.com/dotnet/core/install/linux?WT.mc_id=dotnet-35129-website)
|
||||
|
||||
4. Add the Avalonia.LinuxFramebuffer package in NuGet
|
||||
|
||||
```bash
|
||||
dotnet add package Avalonia.LinuxFramebuffer
|
||||
```
|
||||
|
||||
5. Add StartLinuxDrm code
|
||||
|
||||
```csharp
|
||||
public static int Main(string[] args)
|
||||
{
|
||||
var builder = BuildAvaloniaApp();
|
||||
if (args.Contains("--drm"))
|
||||
{
|
||||
SilenceConsole();
|
||||
// By default, Avalonia will try to detect output card automatically.
|
||||
// But you can specify one, for example "/dev/dri/card1".
|
||||
return builder.StartLinuxDrm(args: args, card: null, scaling: 1.0);
|
||||
}
|
||||
|
||||
return builder.StartWithClassicDesktopLifetime(args);
|
||||
}
|
||||
|
||||
private static void SilenceConsole()
|
||||
{
|
||||
new Thread(() =>
|
||||
{
|
||||
Console.CursorVisible = false;
|
||||
while (true)
|
||||
Console.ReadKey(true);
|
||||
})
|
||||
{ IsBackground = true }.Start();
|
||||
}
|
||||
```
|
||||
|
||||
6. Publish the app to Linux
|
||||
|
||||
```bash
|
||||
dotnet publish demo/Semi.Avalonia.Demo.Drm/Semi.Avalonia.Demo.Drm.csproj -c Release -r linux-x64 --sc -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true
|
||||
```
|
||||
|
||||
Add the following code to the csproj file for AOT publishing
|
||||
|
||||
```xml
|
||||
<PropertyGroup>
|
||||
<PublishAot>true</PublishAot>
|
||||
<IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
|
||||
</PropertyGroup>
|
||||
```
|
||||
|
||||
```bash
|
||||
dotnet publish demo/Semi.Avalonia.Demo.Drm/Semi.Avalonia.Demo.Drm.csproj -c Release -r linu-x64
|
||||
```
|
||||
|
||||
7. Run the program
|
||||
|
||||
```bash
|
||||
sudo ./Semi.Avalonia.Demo.Drm --drm
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
1. Error message
|
||||
|
||||
> Unhandled exception. Avalonia.Markup.Xaml.XamlLoadException: No precompiled XAML found for avares://Semi.Avalonia/Themes/Light/Light.axaml (baseUri: avares://Semi.Avalonia/Themes/Index.axaml), make sure to specify x:Class and include your XAML file as AvaloniaResource
|
||||
|
||||
Solution:
|
||||
|
||||
If you use the Semi release file, do not trim it, otherwise an error will occur.
|
||||
|
||||
24.8.18 update: This issue has been fixed.
|
||||
|
||||
2. Error message
|
||||
|
||||
> Unhandled exception. System.TypeInitializationException: The type initializer for 'SkiaSharp.SKImageInfo' threw an exception.**
|
||||
**--->System.DllNotFoundException: Unable to load shared library 'libSkiaSharp' or one of its dependencies.In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibSkiaSharp: cannot open shared object file: No such file or directory

||||
at SkiaSharp.SkiaApi.sk_colortype_get_default_8888()
|
||||
at SkiaSharp.SKImageInfo..cctor()
|
||||
|
||||
Solution:
|
||||
|
||||
Linux CLI installation
|
||||
|
||||
```bash
|
||||
sudo apt-get install -y libfontconfig1
|
||||
```
|
||||
[Reference](https://github.com/mono/SkiaSharp/issues/509)
|
||||
|
||||
3. Error message
|
||||
|
||||
> Permission denied
|
||||
|
||||
Solution:
|
||||
|
||||
add permission
|
||||
|
||||
```bash
|
||||
sudo chmod +x ./Semi.Avalonia.Demo.Drm
|
||||
```
|
||||
|
||||
4. Error message
|
||||
|
||||
> Unhandled exception. System.ComponentModel.Win32Exception (95): drmModeGetResources failed
|
||||

|
||||
at Semi.Avalonia.Demo.Drm.Program.Main(String[] args)
|
||||
|
||||
Solution:
|
||||
|
||||
The `program.cs` graphics card path is incorrect, it may not be `dev/dri/card1`, see if there are other graphics cards in the `dev/dri` directory such as `card0`.
|
||||
|
||||
24.8.18 update: Avalonia will now automatically detect the graphics card path, so you don't need to specify the graphics card path.
|
||||
|
||||
```csharp
|
||||
return builder.StartLinuxDrm(args: args, card: null, scaling: 1.0);
|
||||
```
|
||||
|
||||
5. Error message
|
||||
>Unhandled exception. System.ComponentModel.Win32Exception (2): Couldn't open /dev/dri/card1
|
||||
at Avalonia.LinuxFramebuffer.Output.DrmCard..ctor(String ) in /_/src/Linux/Avalonia.LinuxFramebuffer/Output/DrmBindings.cs:line 167

|
||||
at Semi.Avalonia.Demo.Drm.Program.Main(String[])
|
||||
|
||||
Solution:
|
||||
|
||||
Unable to open `/dev/dri/card1`, may be the graphics card is mounted to another folder.
|
||||
|
||||
24.8.18 update: Avalonia will now automatically detect the graphics card path, so you don't need to specify the graphics card path.
|
||||
|
||||
```csharp
|
||||
return builder.StartLinuxDrm(args: args, card: null, scaling: 1.0);

# DRM启动步骤
|
||||
|
||||
[English](README.md)
|
||||
|
||||
(Ubuntu 20.04 live server linux-x64 虚拟机测试成功)
|
||||
(Orange Pi Zero2 Ubuntu20.04-arm64 测试成功)
|
||||
|
||||
[Avalonia 官方参考文档](https://docs.avaloniaui.net/docs/next/guides/platforms/rpi/running-on-raspbian-lite-via-drm)
|
||||
|
||||
## 搭建运行环境
|
||||
|
||||
1. Linux端运行命令
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt upgrade
|
||||
sudo reboot
|
||||
sudo apt-get install libgbm1 libgl1-mesa-dri libegl1-mesa libinput10
|
||||
```
|
||||
|
||||
2. 安装测试工具(出现一个彩色立方体说明环境安装完成)
|
||||
```bash
|
||||
sudo apt-get install kmscube
|
||||
sudo kmscube
|
||||
```
|
||||
|
||||
3. [安装.net运行时](https://learn.microsoft.com/dotnet/core/install/linux?WT.mc_id=dotnet-35129-website)
|
||||
|
||||
4. NuGet里面添加Avalonia.LinuxFramebuffer包
|
||||
|
||||
```bash
|
||||
dotnet add package Avalonia.LinuxFramebuffer
|
||||
```
|
||||
|
||||
5. 添加StartLinuxDrm代码
|
||||
|
||||
```csharp
|
||||
public static int Main(string[] args)
|
||||
{
|
||||
var builder = BuildAvaloniaApp();
|
||||
if (args.Contains("--drm"))
|
||||
{
|
||||
SilenceConsole();
|
||||
// By default, Avalonia will try to detect output card automatically.
|
||||
// But you can specify one, for example "/dev/dri/card1".
|
||||
return builder.StartLinuxDrm(args: args, card: null, scaling: 1.0);
|
||||
}
|
||||
|
||||
return builder.StartWithClassicDesktopLifetime(args);
|
||||
}
|
||||
|
||||
private static void SilenceConsole()
|
||||
{
|
||||
new Thread(() =>
|
||||
{
|
||||
Console.CursorVisible = false;
|
||||
while (true)
|
||||
Console.ReadKey(true);
|
||||
})
|
||||
{ IsBackground = true }.Start();
|
||||
}
|
||||
```
|
||||
|
||||
6. 发布程序到Linux
|
||||
|
||||
```bash
|
||||
dotnet publish demo/Semi.Avalonia.Demo.Drm/Semi.Avalonia.Demo.Drm.csproj -c Release -r linux-x64 --sc -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true
|
||||
```
|
||||
|
||||
AOT发布需要在csproj文件中添加以下代码
|
||||
|
||||
```xml
|
||||
<PropertyGroup>
|
||||
<PublishAot>true</PublishAot>
|
||||
<IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
|
||||
</PropertyGroup>
|
||||
```
|
||||
|
||||
```bash
|
||||
dotnet publish demo/Semi.Avalonia.Demo.Drm/Semi.Avalonia.Demo.Drm.csproj -c Release -r linu-x64
|
||||
```
|
||||
|
||||
7. 运行程序
|
||||
|
||||
```bash
|
||||
sudo ./Semi.Avalonia.Demo.Drm --drm
|
||||
```
|
||||
|
||||
## 报错处理
|
||||
|
||||
1. 报错内容
|
||||
|
||||
> Unhandled exception. Avalonia.Markup.Xaml.XamlLoadException: No precompiled XAML found for avares://Semi.Avalonia/Themes/Light/Light.axaml (baseUri: avares://Semi.Avalonia/Themes/Index.axaml), make sure to specify x:Class and include your XAML file as AvaloniaResource
|
||||
|
||||
解决方法：
|
||||
|
||||
如果使用Semi发布文件不要裁剪，如果裁剪会报错。
|
||||
|
||||
24.8.18更新：现在已经修复了这个问题。
|
||||

3. 报错内容
|
||||
|
||||

|
||||
|
||||
解决方法：
|
||||
|
||||
添加执行权限
|
||||
```bash
|
||||
sudo chmod +x ./Semi.Avalonia.Demo.Drm
|
||||
```
|

|
||||
4. 报错内容

|
||||
at Semi.Avalonia.Demo.Drm.Program.Main(String[] args)
|
||||
|
||||
解决方法：
|
||||
|
||||
`program.cs`的显卡路径错误，可能不是`dev/dri/card1`，看在`dev/dri`目录下有无其他的显卡如`card0`。
|
||||
|
||||
24.8.18更新：现在Avalonia会自动检测显卡路径，所以不需要指定显卡路径。
|
||||
|
||||
```csharp
|
||||
return builder.StartLinuxDrm(args: args, card: null, scaling: 1.0);
|

```

解决办法：

找不到显卡路径`dev/dri/card1`，可能是显卡挂载到别的文件夹下了。
