Inspiron N5110 touchpad problems

Hi, I'm having such a tedious problem with my touchpad.
It works greatly when I'm using it continuously, but it seems to be "idle" when I don't. I'll try to explain better with an example: while I'm reading a web page I usually scroll it up and down with the keyboard arrows BUT when I return to the touchpad (i.e. to tap into a text field) it doesn't move instantly... I have to repeat that gesture one or more times till it decides to move!
Does anyone have an idea of how to fix this problem?

In other posts I found there's a parameter named "idle time", that is the time you have to wait since the last keyboard button press. But I didn't find it possible to modify or set this parameter in the Control Panel>Mouse>Touchpad options.

I figured it could also be a driver inefficiency (I'm using the default one by Alps Electric, version 7.1209.101.204) but I'm not an expert on this stuff, so I hope someone could help!
Thanks in advance,

Lannto

 

I would sugges you to do the following:
If you have the dell alps tp driver - uninstall it.
Then reboot.
After reboot use it with the driver which windows left to work with.
Just adjust the pointer speed @ max setting.
There is no other cure, and there will not be any ever

This comes from my 24 hour struggle with random alps drivers to make the darn touch pad work normally (it stutters, freezes, not-scrolling and not "feeling my fingertip"). That is my advice untill you get a proper usb/wl mouse. Cheers!
