Last week, I need to encrypt my hard disk. It is a chance to move my environment to Linux. So I installed Ubuntu 12.04 LTS (Precise Pangolin) amd64 on my T410. The installation process is very smooth and the LUKS(Linux Unified Key Setup) works.
But some tools for IT infrastructure/Collaborations are still 32-bit and not fully support Ubuntu 12.04 64-bit yet.
It took me several days to fix the library dependencies. It’s not easy. Wish the official support will be release sooner this year.
