|
||
sudo systemctl enable game-driver
|
||
sudo systemctl start game-driver
|
||
```
|
||
|
||
## 编译 arm64 架构
|
||
```bash
|
||
CC=aarch64-linux-gnu-gcc CGO_ENABLED=1 GOOS=linux GOARCH=arm64 go build -o game-driver-arm64 .
|
||
```
|
||
|
||
## J8引脚
|
||
```bash
|
||
J8:
|
||
3V3 (1) (2) 5V
|
||
GPIO2 (3) (4) 5V
|
||
GPIO3 (5) (6) GND
|
||
GPIO4 (7) (8) GPIO14
|
||
GND (9) (10) GPIO15
|
||
GPIO17 (11) (12) GPIO18
|
||
GPIO27 (13) (14) GND
|
||
GPIO22 (15) (16) GPIO23
|
||
3V3 (17) (18) GPIO24
|
||
GPIO10 (19) (20) GND
|
||
GPIO9 (21) (22) GPIO25
|
||
GPIO11 (23) (24) GPIO8
|
||
GND (25) (26) GPIO7
|
||
GPIO0 (27) (28) GPIO1
|
||
GPIO5 (29) (30) GND
|
||

|
||
## 极简桌面环境并自动登录
|
||
|
||
### 安装 xorg i3
|
||
```bash
|
||
sudo apt install xorg i3-wm
|
||
```
|
||
|
||
### 自动启动 Xorg 和窗口管理器
|
||
|
||
编辑 `.bashrc`文件，在文件的末尾添加以下行：
|
||
```bash
|
||
if [ -z "$DISPLAY" ] && [ "$(tty)" = "/dev/tty1" ]; then
|
||
startx
|
||
fi
|
||
```
|
||
|
||
这会在你登录后，自动启动 Xorg 和窗口管理器。该脚本检查当前是否在 tty1 控制台（默认终端）上
|
||
|
||
### 自动登录
|
||
|
||
编辑 `/etc/systemd/system/getty.target.wants/getty@tty1.service` 文件，将 `ExecStart` 行修改为：
|
||
```bash
|
||
ExecStart=-/sbin/agetty --autologin <your_username> --noclear %I $TERM
|
||
```
|
||
其中：
|
||
- <your_username>：替换为你想自动登录的用户名。
|
||
|
||
### 禁用 i3bar 状态栏
|
||
|
||
编辑 `~/.config/i3/config`，将如下行注释掉：
|
||
```bash
|
||
# bar {
|
||
# status_command i3status
|
||
# }
|
||
```
|
||
|
||
### 配置 i3
|
||
|
||
安装 `unclutter`：
|
||
```bash
|
||
sudo apt install unclutter
|
||
```
|
||
|
||
编辑 `~/.config/i3/config`，添加如下行：
|
||
```bash
|
||
exec --no-startup-id unclutter -root # 隐藏鼠标
|
||
exec --no-startup-id xset dpms 0 0 0 # 关闭屏幕自动关闭
|
||
exec --no-startup-id xset s off # 关闭屏幕保护
|
||
```
|
||
|
||
不使用 `xset -dpms` 来禁用屏幕自动关闭，因为当使用 `xset dpms force off` 或 `xset dpms force on` 时，会导致禁用失效
|
||
|
||
### 安装中文字体和 emoji 字体
|
||
|
||
```bash
|
||
sudo apt install fonts-noto-cjk fonts-noto-color-emoji
|
||
```
|
||
|
||
## 安装浏览器作为默认启动页面
|
||
|
||
### 安装浏览器
|
||
|
||
```bash
|
||
sudo add-apt-repository ppa:xtradeb/apps
|
||
sudo apt update
|
||
sudo apt install ungoogled-chromium
|
||
```
|
||
|
||
### 设置默认启动页面
|
||
|
||
编辑 `~/.config/i3/config`，添加如下行：
|
||
```bash
|
||
exec --no-startup-id ungoogled-chromium --kiosk --disable-extensions --disable-translate --app=<your_url>
|
||
```
