When you go in menu Help ->About system you should be able to see it. Also,
when you go to Python Shell, you can type:
import wx
wx.version()

In wxPython >= 2.9, there is a method IsDisplaySupported which would help
to understand more about the problem [1]. The only thing which I know you
could try is to install wxPython 3. You can either compile it yourself or
update Ubuntu to the latest one and install the package. However I can't
guarantee it helps.
