Ubuntu Feisty on IBM/Lenovo T60

I replace my old laptop (IBM T42) with Lenovo T60. Lenove T60 fixes the following T42 problem :

• T60 can display running video in Beryl cube with correct perspective
• T60 support dual screen (one builtin LCD screen plus one external projector)
• T60 support all sophisticated Beryl effect (i.e. rain, zoom, etc.) without CPU problem

Standard Ubuntu Feisty Fawn installation gives most functionality. I will post every single changes I made on my PC to this blog.
