@jun-yang - I haven't been able to reproduce your issue. I tried:
1) OEM mode install on an Intel-GPU system
2) OEM mode install on an Nvidia-GPU system
In all cases, encrypted home directory seemed to work fine for me and I was never prompted for a passphrase to unlock the cryptoswap (note that I had installed all the updates prior to running "Prepare for shipping to user").
Is your 15.04 install completely up-to-date? Also, now that the ecryptfs-utils/libecryptfs1 update has landed in vivid-updates, you only need do to this to make sure you have a fully up-to-date system:
