Deactivate MEvent.CASE in Java IDEs

I'm using MATLAB R2014a on my laptop running Ubuntu 14.04 LTS, and am experiencing a rather annoying issue. Whenever I use the two-finger scrolling gesture on my touchpad in either the editor or the main window, the following output appears in the command window:

MEvent. CASE!

While the scrolling works, this line is output over and over again as I continue to perform the gesture.

Any ideas for how to stop this from happening?

NOTE: It also occurs in Processing and Arduino IDEenter image description here


As a user I wouldn't want to type the above command everytime I open MATLAB. So I searched a bit on matlab 'startup' command line section, and the 'search path' section. I solved my problem after doing the following simple steps:

  1. See your userpath by typing userpath in MATLAB console: For linux it is: home/username/Documents/MATLAB/
  2. Create a file 'startup.m' having only one line, which will disable Mevent.CASE! (Below is the text to copy)

    !synclient HorizEdgeScroll=0 HorizTwoFingerScroll=0
  3. Place the created startup.m file in your userpath folder as defined in MATLAB.

  4. Now as soon as you place this file in your userpath, restart MATLAB.
  5. Verify by seeing ans = 0 in the workspace section.

It worked for me on Ubuntu 15.04 running MATLAB R2015b, I hope it works for you all as well.

Note: This is an improvement to @someDude and @Slothworks answer.
