Hi there. I am running Debian "Sid" and have sussed out the upgrading, etc. However, downgrading is a mystery to me. I need to revert to glibc2.2, as my ATI drivers don't work with glibc2.3. I can download older versions, or change my sources to "stable" I guess. But then what? How can this be done simply? :-) Thanks in advance, Dietrich
