I'm using Xubuntu 12.10 on an HP Pavilion dm1 and wondering what's up with the smooth-scroll behavior.
Let's say I try to use two-finger scrolling in the Document Viewer while looking at a PDF. If I scroll while the pointer is on top of the document, i.e. in the middle of the window, I don't get smooth behavior. The page just acts the way it used to before smooth scrolling existed.
However, if I put my pointer on top of the scrollbar on the right side and try to use the trackpad to scroll, smooth scrolling works, and it works great! No more jumpy pages or anything.
My question is: why is smooth scrolling only half-working and how to I fully enable this functionality so that I don't always have to carefully position my pointer over the scrollbar (what's the point of even having two finger scrolling if I have to go to the scrollbar anyway?).
Thanks in advance.
edit: I should add that smooth scrolling doesn't work at all in Chromium without installing the Chromium Wheel Smooth Scroller extension; but I already understand why Chromium works like that.
