[ubuntu] Using xorg edgers ppa with QQ

view story

http://ubuntuforums.org – Okay guys I have a question here about testing; I have an nvidia optimus laptop and only the newer nvidia beta drivers work with The Bumblebee Project for my chip (its a new chip). So i needed to add the xorg edgers PPA to for when i installed TBP for it to grab the newer drivers, it also upgraded a load of xorg stuff like intel drivers and all that. After this was installed I removed the xorg edgers PPA. So to my question - will it mess anything up for me while testing? If newer versions come into main ubuntu repo will it overwrite the xorg edgers ppa versions I have at the moment? (Hardware)
