Mar*_*ter 7 vnc raspberry-pi raspberry-pi2 raspberry-pi4
我正在尝试在我的 Raspberry Pi 4 上进行无头安装,运行 Raspberry Pi OS,通过 Raspberry Imager 安装。安装或多或少是普通的,因为我所做的唯一更改是连接(设置 SSH、无线和 VNC,如本指南中所述: https: //www.tomshardware.com/reviews/raspberry-pi-headless-设置方法,6028.html)。
当我通过 VNC 登录时,出现“当前无法显示桌面”错误。应该可以通过 raspi-config 更改屏幕分辨率来修复,但这会使 pi 无响应。将 pi 设置为使用“G3 Legacy”应该可以在重新启动后或不重新启动后解决该问题(答案各不相同),但在这两种情况下似乎都没有什么区别。
有谁知道如何通过 VNC 连接到我的 pi?
谢谢 :)
基本上应该足以指定 HDMI 模式。我有一个 Raspberry Pi4 headless,这是我在 /boot/config.txt 中的配置

然后我禁用加密并设置 VNC 密码。此外,如果您要通过 VNC 查看 raspistill/raspivid 预览,则必须启用此功能:RealVNC Viewer > 菜单 > 选项 > 故障排除 > 优化屏幕捕获 - 选择“启用直接捕获模式”
