I upgraded from 18.04.4 LTS to 20.04 and now my xfce VNC environment is broken. There are no title or command bars (Close, Maximize, Minimize) on windows any longer. Only the menu bar (File, Edit, View, etc.)

This is my ~/.vnc/xstartup:

#!/bin/sh

#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

# Fix to make GNOME and GTK stuff work
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

# exec /etc/X11/xinit/xinitrc
xrdb $HOME/.Xresources
xsetroot -solid grey

xfce4-session &

# before Ubuntu 18.04:
# gnome-settings-daemon &

# Ubuntu 18.04 and later:
/usr/lib/gnome-settings-daemon/gsd-xsettings &

And here is a screenshot of what it looks like. You can see the launcher appears to be cut thinner on the top and bottom as if a border is missing. enter image description here

  • I'm not quiet sure, but has wayland sth to do with it? I know the gnome session starts by default with wayland, but how about xfce? VNC relies on the X-server – kanehekili Jul 17 '20 at 20:19

This is one of the known 20.04 issues mentioned in the release notes. "Window decorations are not displayed with tightvncserver. Users depending on VNC are advised to wait until 20.04.1 or use an alternative window manager for VNC until this is resolved."

Here is the bug report about it. https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1860921

I fixed it by installing xfwm4 4.14.5 from here. It was not usable without the fix. (If the link breaks again, please try doing a Google search on "xfwm4_4.14.5-1_amd64.deb").
