我正在尝试在 Ubuntu 20.04 LTS 上配置 Gnome-Desktop。
我能够使用 Real VNC Viewer、Apple VNC Screen Share 和其他 VNC 查看器查看桌面，我可以运行我的应用程序，桌面管理器可以运行，在服务器内可以复制/粘贴，等等。
但是，背景是灰色的（没有壁纸），缺少图标（例如时钟，音频等），客户端和服务器之间无法进行复制/粘贴，右键单击不起作用。
以下是我安装的内容：
sudo apt-get install ubuntu-gnome-desktop
sudo apt-get install tightvncserver xtightvncviewer tightvnc-java
sudo locale-gen de_DE.UTF-8
sudo apt-get install xfonts-75dpi
sudo apt-get install xfonts-100dpi
sudo apt-get install gnome-panel
sudo apt-get install metacity
sudo apt-get install light-themes
touch ~/.Xresources
vncpasswd
这是我的 ~/.vnc/xstartup 文件：
#!/bin/sh
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XKL_XMODMAP_DISABLE=1
export XDG_CURRENT_DESKTOP="GNOME-Flashback:Unity"
export XDG_MENU_PREFIX="gnome-flashback-"
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
gnome-session --session=gnome-flashback-metacity --disable-acceleration-check &
gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal & 1,1
我的屏幕如下
Ubuntu 20.04 LTS 上有三个版本的 dbus：

答案1
现在可以正常工作了。（但顶部栏右上角的图标仍然缺失。）
我所做的就是卸载 Anaconda 版本的“dbus”。
这是我的.vnc/startup：
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XKL_XMODMAP_DISABLE=1
export XDG_CURRENT_DESKTOP="GNOME-Flashback:GNOME"
export XDG_MENU_PREFIX="gnome-flashback-"
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
gnome-session --builtin --session=gnome-flashback-metacity --disable-acceleration-check --debug &
nautilus &
gnome-terminal &
并运行 /usr/bin/dbus-daemon：
(base) ubuntu@ip-10-0-1-82:~$ ps -ef | grep ubuntu | grep dbus
ubuntu 2546 2526 0 18:59 ? 00:00:00 /usr/bin/dbus-daemon --session --address=systemd: --nofork --nopidfile --systemd-activation --syslog-only
ubuntu 2830 2825 0 19:00 ? 00:00:00 /usr/bin/dbus-daemon --config-file=/usr/share/defaults/at-spi2/accessibility.conf --nofork --print-address 3
ubuntu 6794 1 0 19:26 pts/1 00:00:00 dbus-launch --exit-with-session /usr/libexec/gnome-session-binary --systemd --builtin --session=gnome-flashback-metacity --disable-acceleration-check --debug
ubuntu 6795 1 0 19:26 ? 00:00:00 /usr/bin/dbus-daemon --syslog --fork --print-pid 5 --print-address 7 --session
ubuntu 6891 6881 0 19:26 ? 00:00:00 /usr/bin/dbus-daemon --config-file=/usr/share/defaults/at-spi2/accessibility.conf --nofork --print-address 3
答案2
XDG_CURRENT_DESKTOP应该GNOME-Flashback:GNOME。- 您还需要安装
gnome-flashback。 gnome-settings-daemon不存在，删除它。- 还删除
gnome-panel和metacity，将由开始gnome-session。
