在 Ubuntu 18.04 上配置 TigerVNC systemd 程序

我一直在嘗試讓 TigerVNC 在桌面 Ubuntu 18.04（GNOME 和所有）的全新安裝上工作。執行vncserver :1 -localhost no讓我可以很好地連接，但我的 systemd 服務似乎不起作用。

系統啟動後的日誌：

Xvnc TigerVNC 1.7.0 - built Dec  5 2017 09:25:01

vncconfig: unable to open display ":1"

** (process:1184): WARNING **: 15:13:28.311: Could not make bus activated clients aware of XDG_CURRENT_DESKTOP=GNOME environment variable: Could not connect: Connection refused

在終端（ ）中手動啟動 vncserver 後登錄vncserver :1 -localhost no：

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":1"
     after 175 requests (174 known processed) with 0 events remaining.

啟動：

#!/bin/sh

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
vncconfig -iconic & dbus-launch --exit-with-session gnome-session &

vncserver@.service

[Unit]
Description=TigerVNC Service
After=syslog.target network.target

[Service]
Type=simple
User=<user>
PAMName=login

PIDFile=/home/<user>/.vnc/%H:%i.pid
ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1
ExecStart=/usr/bin/vncserver :%i -localhost no
ExecStop=/usr/bin/vncserver -kill :%i

[Install]
WantedBy=multi-user.target

經過反複試驗，我決定在使用者登錄後在使用者模式下執行該程序。使用者登錄後服務啟動，並啟用自動登錄，它可以很好地滿足我的目的。

我刪除了文件並使用以下內容/etc/systemd/system/vncserver@.service創建了一個新文件（並創建了失去的文件夾）。$HOME/.local/share/systemd/user/vncserver@.service

vncserver@.service

[Unit]
Description=TigerVNC Service

[Service]
Type=forking
ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1
ExecStart=/usr/bin/vncserver :%i -localhost no
ExecStop=/usr/bin/vncserver -kill :%i

[Install]
WantedBy=default.target

然後我啟用了該服務systemctl daemon-reload --user並使用systemctl enable vncserver@1 --user.
