Problem:

I am able to logon without problems, but the top menu is not displayed. I am just able to see the background picture. I am further not able to for example rightclick the mouse to display menu.

Workaround:

I am able to workaround the problem by first starting an x2goclient session from for example a windows platform with intel cpu or from a memory stick with the ubuntu os booting using a pc with intel cpu, and then just close the session without logout clicking x in the top right corner of the screen. Resuming this session from the xubuntu mini pc, I do get the menu displayed correctly even though the colors get a little distorted.

Analysis:

I have compared processes running starting a session from the xubuntu pc with no menu displayed as compared to a session in which the menu is displayed correctly, and it seems like processes have not been started when no menu is displayed, for example the following processes:

xfwm4 /usr/lib64/xfce4/panel/wrapper /usr/lib64/xfce4/panel/plugins/libactions.so 2 14680095 actions Handlingknapper Logg ut, lås eller andre systemvalg /usr/lib64/xfce4/panel/wrapper /usr/lib64/xfce4/panel/plugins/libsystray.so 6 14680097 systray Systemkurv Område som viser beskjedikoner

To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) xfce4-panel-Message: Plugin "xfce4-mixer-plugin-15" was not found and has been removed from the configuration
