1. true it is cumbersome way to start new discussion
a) installer is universal for Linux.
b) the beta page contain additional information. link to them from stable version page is convenient.
c) normal linux driver should work with mobility graphics too. even on windows separation of mobility and desktop drivers are quite artificial.
Thanks Himanshu and Nou.
Reg. your first question: Yes, a way to start a new discussion while on an existing one seems useful. Let me investigate this.
