OK, so it's sort of like Windows then - when you tried everything else and nothing works yet, just reinstall? I find these difficulties people are having with X somewhat amusing - my two personal machines have been on ~arch since forever, and even with huge amounts of activity in the last 18 months on X, gcc and glibc, all upgrades have been as smooth as silk for me. A possibility (speaking generically now), is that X and it's drivers and a bunch of other stuff all need to be compile with the same gcc. nvidia is like this and silently barfs if you don't. It's easy to get right with an upgrade - go to the latest - but a downgrade is a completely different animal (you don't know what you should be going back to). -- alan dot mckinnon at gmail dot com
