I just installed VirtualBox4.2 on Ubuntu 13.04. When I open VirtualBox, all seems well, until I try to create an new VM, at which point, lightdm crashes, and I am forced (eventually) back to the login screen.
is anyone running VirtaulBox in Ubuntu 13.04 and having the same issue? Does anyone know a fix to this?
here is what looks like relivent
