The ICS builds don't support the lapdock at the moment... and probably wont until Motorola comes out with their own build. The only solution I've come across is to use Safestrap and swap back to the original OS when you want to use the lapdock feature. I'm currently trying to work out if it's possible to use the Ubuntu (any linux hash) as the lapdock applications, so far I've been having no luck since all the custom stuff seems to need an intact webdock app to edit, which currently doesn't support ICS.
the other day i had to hop on verizon's lapdock500 deal and later that night, i flashed axi0m aokp. has anyone had any issues running axi0m with the lapdock?
