I have Ubuntu 12.04 as a primary desktop.  The hardware is a P9X79 
motherboard with USB keyboard and USB mouse.  I do not use Unity, etc. I 
start TWM and use xterm most of the time.

If I boot linux-3.2.0-38-generic (Ubuntu 12.04), and fill the xterm 
buffer with lines of text (repeat ls;ls;...;ls) and then grab the left 
scroll bar with mouse-center button and scroll up, the effect is a 
smooth scrolling of the text lines.

If I boot linux-3.2.0-39-generic (Ubuntu 12.04), or later linux kernel, 
and fill the xterm buffer with lines of text (repeat ls;ls;...;ls) and 
then grab the left scroll bar with mouse-center button and scroll up, 
the effect is a slinky scroll of the text.  The latest kernel I have is 
linux-3.13.0-1, which has the slinky scroll.

I installed Ubuntu 14.04 on a spare disk and configured it similar to 
the 12.04 system.  After updating, it now runs Linux 3.13.0-6-generic. 
If I fill the xterm buffer with lines of text (repeat ls;ls;...;ls) and 
then grab the left scroll bar with mouse-center button and scroll up, 
the effect is a smooth scrolling of the text lines.

Question: It appears the slinky scroll is related to Ubuntu 12.04, not 
the particular kernel.  Is this true?
