Я хотел бы получить доступ к моему Ubuntu 16.10 VPS (Contabo) с использованием среды GNOME с VNC, однако мне все еще приходится сталкиваться с некоторыми проблемами, которые я не мог решить так далеко. Для того, чтобы установить и настроить программное обеспечение, я побежал следующие команды:Как правильно настроить файл xstartup для TightVNC с помощью среды Ubuntu VPS GNOME
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
Файл ~/.vnc/XStartup первоначально содержит следующие строки:
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
# Fix to make GNOME work
export XKL_XMODMAP_DISABLE=1
/etc/X11/Xsession
При запуске сервера VNC с помощью vncserver -geometry 1920x1200 все прекрасно смотрится в соответствии с файлом журнала в ~/.vnc
17/02/17 11:47:48 Xvnc version TightVNC-1.3.10

Я могу успешно подключиться с моего ПК с Windows через VNCViewer и увидеть серое окно.
Теперь, что мне непонятно, это то, что я должен изменить в ~/.vnc/xstartup, чтобы получить Gnome running. Я пробовал много разных настроек.
E.g. когда я изменяю XStartup к
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
# Fix to make GNOME work
export XKL_XMODMAP_DISABLE=1
/etc/X11/Xsession
#gnome-session &
gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
и подключиться через VNC, я получаю следующее сообщение об ошибке в лог VNC файла:

И это то, что я могу видеть VNCViewer: 
До сих пор я не смог исправить проблемы в файле журнала. Большое спасибо за Вашу помощь.
UPDATE 1
Если я адаптируются ~/.vnc/XStartup согласно UPDATE 2 из muktupavels ответить на мой лог-файл выглядит следующим образом при подключении через VNCViewer:

Это скриншот от GUI: 
Теперь часы e tc. видна на верхней панели. Тем не менее, рабочий стол по-прежнему серый, и щелчок правой кнопкой мыши не работает.
Также некоторые приложения, такие как терминал GNOME, сначала не запускались.Когда я попытался запустить терминал с помощью Xterm я получил следующее сообщение об ошибке:
Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.gnome.Terminal': timed out
После выполнения следующих команд и перезагрузки ГНОМ терминалов и все другие программы работы:
sudo locale-gen
sudo localectl set-locale LANG="en_US.UTF-8"
sudo reboot
UPDATE 3
--debug параметр gnome-session cmd in ~/.vnc/xstartup. После перезагрузки VNCserver я получил следующее сообщение в ~/.xsession-errors:
