我正在尝试将 rdp 从带有 Raspberry pi 操作系统的 rpi 4 设置到使用 Remmina 运行 Arch Linux 的笔记本电脑。
目前我无法使用 Remmina 从我的 rpi rdp 到任何 Arch 机器（有两台）。但是，使用 rdesktop 作为客户端确实有效。
rdesktop 是一个不受欢迎的解决方案，因为我希望能够访问 Remmina 的功能，并可能以某种临时 kiosk 模式直接从 X 运行 Remmina。
watch systemctl status xrdp这是在尝试使用 Remmina 从 rpi 连接到 Arch 计算机期间运行时，Arch VM/BM 上出现的令人讨厌的错误：

我有4台机器：
- Windows 10 拉皮
- 虚拟机中的 Arch Linux
- “裸机”上的 Arch Linux
- rpi“裸机”上的 Raspberry pi 操作系统
以下是我迄今为止经历过的成功/失败场景，这些场景已经被重复和证实：
| 结果 | 来源 | 会话协议 | 目的地 |
|---|---|---|---|
| PF | 全部 | 通过 RDP 的 VNC | 转速 |
| PF | 全部 | xorg 通过 rdp | Arch VM/BM |
| S | WIN10 | xorg 通过 rdp | 转速 |
| S | 转速 | 标准 RDP | WIN10 |
| S | WIN10 | 通过 RDP 的 VNC | Arch VM/BM |
| S | Arch VM/BM | 标准 RDP | WIN10 |
| TF | 转速 | 不适用 | Arch VM/BM |
| S | Arch VM/BM | xorg 通过 rdp | 转速 |
- S = 成功
- TF = 完全失败 = 在会话管理器可以获取非法凭据之前连接断开
- PF = 部分失败 = 没有启动窗口管理器，只有会话管理器的背景仍然存在
- ALL = 所有机器
- VM/BM = 虚拟机/裸机
尽管在 Arch VM/BM 上安装了 xorgxrdp 软件包，但我无法启动 Xorg 会话。
这里最重要的是建立从我的 rpi 到我的 Arch 机器的 rdp 会话，因为 rpi 是作为某种 rdp 门户运行的。
我尝试关闭 xrdp-sesman 以查看是否至少会导致建立连接。我的想法可能只是会话管理器有问题，它假设连接是单独建立的。此配置不起作用，似乎无法连接。

答案1
答案可以在xrdp github上找到这里
基本上，xrdp：
服务器不发送，
GlyphCacheCapabilitySet但没问题。服务器不应该进行字形缓存，除非客户端确实通告字形缓存功能。
作为 Remmina 用户的解决方法，打开有问题的连接配置文件的连接设置，转到“高级”并选择“字形缓存”和“放宽顺序检查”
