我已经在 Ubuntu 20.04.4 中安装了 tigervnc，但运行不佳。
我的单元文件如下（我想像服务一样运行）：（/etc/systemd/system/vncserver.service -rw-r--r-- 1 root root 309 Mar 17 22:00 vncserver.service）
[Unit]
Description=TightVNC server

我运行以下命令：
sudo systemctl daemon-reload
sudo systemctl start vncserver.service
Job for vncserver.service failed because the control process exited with error code.
See "systemctl status vncserver.service" and "journalctl -xe" for details.
当我检查时，出现以下消息：
sudo systemctl status vncserver.service
