Not sure if this is the right category to post this problem, sorry if it's not!
I had hardy-backports checked in hardy, and i must have installed the newest version of the qt libraries (4.4) without being aware of it. This has caused some problems for me (primarily with skype video), so I'd like to downgrade to 4.3.4 (see http://ubuntuforums.org/showthread.php?t=795676 for why). The only way i can think of doing this is uninstalling them, unchecking backports, reloading, then installing the old version. the only problem is there are a lot of qtlib packages and I'm not sure which ones to uninstall. can anyone help?
also, is there any easier way to downgrade?
