我有一个用户帐户“virendar”，我在其中配置了 vnc。我注意到，甚至有两个过程。我尝试终止两个进程，几秒钟内，我看到一个进程自动启动。我不确定这是如何自动启动的。当我检查 vncservice 的状态时，它处于停止状态。当我启动它时，我看到第二个 vnc 进程正在启动。

我们如何缩小重复 vnc 进程的根本原因？我想知道重复过程是如何自动启动的。

答案1
通常你应该检查：
/etc/cron.daily/
/etc/cron.hourly/
查看
crontab -e
作为标准用户、root 和系统 vnc 用户。
另外检查目录是否包含任何文件
/etc/rc.d/
检查此文件是否包含以系统开头的任何条目：
/etc/rc.d/rc.local
在这里检查单位：
/etc/systemd/system/
请记住，如果您正在运行 vnc 会话，那么每个核心进程的两个副本肯定也会运行。
答案2
看起来您有两个显示器？
一个用于DISPLAY=:1另一个用于DISPLAY=:2，在 rfbports 5901 和 5902 上运行。
您可以尝试连接到 5902 而不是 5901，看看有什么。
（检查/etc/systemd/system/vncserver@:2.service）
编辑：
检查单位状态：
systemctl status vncserver@:1.service
systemctl status vncserver@:2.service
