Pavilion dm4-1160 erratic touchpad solved with a script

I wrote a simple bash script to solve the erratic touchpad of my notebook HP dm4-1160us.

A left button click is emulated by a fast tap on the touchpad. The vertical scrolling is a narrow area on the right edge of the touchpad. Now, two fingers can touch the pad without any erratic jumps of the pointer. It's possible to grab and move a window too; just move the mouse pointer on the top area of the window, then double taps quickly and keep the finger on the pad while you grab the window. Unfortunately the right button still doesn't work. (Check my next post - October 19 - the right button is emulated too!)

The script is below.
- Copy and past the code in gedit, save it as for instance.
- Make it executable.
- Start it automatically with gnome ( System->Preference->StartUp Applications->Add and provide the command ).
Of course, you can run this script from the console, just to check it.
If you find some improvement, let me know!

How does one make a text file ( executable? Do you mean just change the file extension to *.exe?

at a command prompt

You don't actually need the .sh extension. In Linux, extensions mean nearly zero.
