[ubuntu] running Virtualbox from the icon

I have installed and run virtualbox from a term window using sudo. I want my wife to start using my Sys76 machine but she doesn't like using term windows.

I setup a VB icon, but it launches a new VB setup. I want to have it start the VB I have already setup and run.

I tried to setup and have it use my previous VDI disk , but it does not see it.

Did I miss something

Thanks

Darrell
