Šedá obrazovka Ubuntu 18.04 Vnc?

Mám problémy s načítáním plochy gnome přes vnc

zpočátku jsem postupoval podle tohoto průvodce pro xfce vnc
https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-18-04

pracovní konfigurace Xfce:

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startxfce4 &

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
/usr/bin/autocutsel -s CLIPBOARD -fork
vncconfig -iconic &
x-terminal-emulator -geometry 80x24x10x10 -ls -title "$VNCDESKTOP Desktop" &
gnome-session &

Snažím se to změnit, abych povolil relaci gnome:

Našel jsem konfiguraci z:
Jak zajistit, aby VNC Server fungoval s ubuntu-desktop bez xfce

export XKL_XMODMAP_DISABLE=1
# unset SESSION_MANAGER
# unset DBUS_SESSION_BUS_ADDRESS

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24x10x10 -ls -title "$VNCDESKTOP Desktop" &

gnome-session &
gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal &

Tím se mi zobrazí šedá obrazovka, ale Nautilus funguje (tak nějak)

můj protokol vypadá takto:

Udělal jsem nějaký průzkum a viděl jsem, že použití gnome flashbacku by mohla být cesta

Související:Nelze hibernovat dvakrát?

změnil moji konfiguraci na:

#!/bin/sh

export XKL_XMODMAP_DISABLE=1
export XDG_CURRENT_DESKTOP="GNOME-Flashback:GNOME"
export XDG_MENU_PREFIX="gnome-flashback-"

gnome-session --session=gnome-flashback-metacity --disable-acceleration-check --debug &

log vypadá lépe, ale neexistuje nebo je neplatný soubor:

Jsem docela nový v linuxu a ubuntu a pracuji se svým ubuntu boxem bezhlavě přes notebook s Windows

Může někdo pomoci?

Na zdraví

Přijatá odpověď:

Postupujte takto:

1. Nainstalujte gnome-session-flashback :

    sudo apt install gnome-session-flashback
   

2. Přidejte toto do ~/.vnc/xstartup :

    #!/bin/sh
    autocutsel -fork
    xrdb $HOME/.Xresources
    xsetroot -solid grey
    export XKL_XMODMAP_DISABLE=1
    export XDG_CURRENT_DESKTOP="GNOME-Flashback:Unity"
    export XDG_MENU_PREFIX="gnome-flashback-"
    unset DBUS_SESSION_BUS_ADDRESS
    gnome-session --session=gnome-flashback-metacity --disable-acceleration-check --debug &
