After trying for a while finally managed to run Ubuntu on my Acer D255 e, using seagate external HDD. All is working fine apart from mouse. Although trackpad allow me to select program and open application. I cannot click select within application, the only way I can click select is using a combination of tab/arrow keys/enter when within an application.

In universal access under the pointer and clicking: Mouse key is OFF Simulated secondary click ON Hover click OFF

In mouse and touchpad Under all setting General: primary button left/ double click half way Touch pad: ON Slow 1/3 of the way Only Tap to click is selected

My system.

Running Ubuntu 14.04 LTS Memory 2GB Intel Atom CPU N555 @1,50GHz x 4 32-Bit

Any pointers on how to fully enable trackpad and mouse click? So that I can fully enjoy the wonder of using Ubuntu beautiful features. Thanks

After doing some research, removing and reloading the trackpad/mouse driver appear to fix the problem temporarily.

Open a terminal (Ctrl-Alt-T) and run

Code: sudo modprobe -rv psmouse sudo modprobe -v psmouse

To set various options of Synaptics touch pads, take a look at
man synclient
