What do you do when the electrical system fails?

I found this article on the Airbus 320, which has an all glass
cockpit:

"The energy supply is backed up in several ways. Along with one
generator per engine, a third generator is powered by the APU. A
fourth power supply is available by extending a little fan generator
into the airstream. The chances of experiencing a complete power loss
in an A320 are calculated to be at around one in one trillion. Should
this happen, the above mentioned mechanical system of the rudder and
the elevator trim ensure a safe landing."

That's all well and good for the failure modes of the on-board generators.
How did they protect against the power surge that a lightning hit could
impose that could take out the PFDs?
