Missing main toolbar Virtualbox KDE


System:    Host: home-pc Kernel: 4.14.54-1-MANJARO x86_64 bits: 64 compiler: gcc v: 8.1.1 
           Desktop: KDE Plasma 5.13.2 tk: Qt 5.11.1 Distro: Manjaro Linux 17.1.11 Hakoila 

Missing main toolbar on Virtualbox 5.2.14 after KDE 5.13 like this:

Delete home/.config/VirtualBox. Start VirtualBox:

I close VirtualBox and start:

Main toolbar is missing in other programs like Kate. But Kate have option to show it.


This is a known issue and already reported.


A workaround till a permanent fix in order to keep the Toolbar after you enable it by right clicking on the Text Toolbar, the application needs to be closed from
File > Exit or Ctrl+Q and NOT from X nor Alt+F4.



The bug is, that this setting is not remembered, unless you close Virtual box via File -> Quit.


In ~/.config/VirtualBox/VirtualBox.xml, change:
<ExtraDataItem name="GUI/Toolbar" value="false"/>
<ExtraDataItem name="GUI/Toolbar" value="true"/>

VirtualBox shows no options in its GUI

Super ! Thanks ! worked like charm !
