无法通过 contabo VPS 在 Ubuntu 22.02 上打开应用程序

Question

桌面看起来是空的，图标根本就不显示。我无法打开设置、文件、电源等。我打开终端没有任何问题。这是 xrdp 的初始启动文件：

#!/bin/sh
# xrdp X session start script (c) 2015, 2017, 2021 mirabilos
# published under The MirOS Licence

#Improved Look n Feel Method
cat <<EOF > ~/.xsessionrc
export GNOME_SHELL_SESSION_MODE=ubuntu
export XDG_CURRENT_DESKTOP=ubuntu:GNOME
export XDG_DATA_DIRS=
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
EOF

# Rely on /etc/pam.d/xrdp-sesman using pam_env to load both
# /etc/environment and /etc/default/locale to initialise the
# locale and the user environment properly.

if test -r /etc/profile; then
        . /etc/profile
fi

test -x /etc/X11/Xsession && exec /etc/X11/Xsession
exec /bin/sh /etc/X11/Xsession

桌面看起来是这样的：
