Enable wallpaper scrolling for HTC Sense 4+
I have a HTC One X too, and I hadn't noticed yet that wallpaper scrolling is not working anymore. After some searching in the settings, I haven't found the solution to your problem. So I think that I have to conclude that there is no option to restore this functionality.

Reverting back to previouse Sense versions is not an option as far as I know. Rooting is an option, but I guess that this will not fix the problem, though I cannot really say for sure it will or will not.
