x11vnc系统服务故障
x11vnc系统服务故障
提问于 2022-08-04 14:34:41
使用Ubuntu22.04LTS并在重新安装之后，我将尝试设置x11vnc服务，以便在服务器启动(systemd)时执行。目前，我可以在服务器中手动启动x11vnc，并能够从客户端(端口5900)连接到服务器。我需要将x11vnc配置为一个服务，以便在服务器启动时永久启动并运行。
按照这个方向，我遵循了创建服务的“正常”过程：https://help.ubuntu.com/community/VNC/Servers。下面是我的服务器中的配置：
sudo nano /lib/systemd/system/x11vnc.service
[Unit]
Description=Start x11vnc at startup.
After=multi-user.target
[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -loop -forever -bg -rfbport 5900 -xkb -noxrecord -noxfixes -noxdamage -shared -norc -auth /run/user/1000/ubuntu/Xauthority -rfbauth /etc/x11vnc.pass
[Install]
WantedBy=multi-user.target
sudo nano /etc/systemd/system/x11vnc.service
[Unit]

After=display-manager.service
[Service]
ExecStart=/usr/bin/x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :1 -auth guess -rfbauth /etc/x11vnc.pass

问题是您的系统找不到您正在使用的.Xauthority文件。它以根用户身份运行x11vnc，并使用-auth guess选项，这意味着它应该知道xauth文件是什么，并使用它。但是，作为root运行的进程如何在主目录中查找呢？不过，您可以使用-auth /path/to/.Xauthority显式传递用于xauth的文件。这样，它就不必“猜测”并能够找到文件。
