Installed Ubuntu 12.10 and KDE as my primary desktop manager. My system is very stable and I have no issues so far. Just a minor UI glitch.

My Eclipse IDE (also Chrome) looks ugly and dont behave to have KDE application L&F. Google search says,

"GTK-Qt Theme Engine is a plugin for GTK that allows GTK applications to use Qt widget styles"

Not sure how to install this. Really appreciate your help on this.
