Do your laptop RAM a favour – Do NOT upgrade your touchpad driver



Synaptics is the most common touchpad driver for laptops. However, Synaptics touchpad driver takes SO MUCH RAM, even when you uninstall the "Scrype" application that comes with most recent versions of it.


The 236 MB above is just a small number. I have set the process priority to "Low" to get only this. The default priority of the process is "Above Normal". If you are like me and rarely shut down your laptop, depending more on Sleep, etc.. this is going to bite hard because it just keeps growing….



Here is one interesting discussion about it:

This forum is a gold mine for laptop owners. I might blog how it helped me in other more important issues.

Form the forum I got a really nice tip:

The leak has been reported on Lenovo Forums, and has been reproduced on their end. You can roll back to an earlier driver. and earlier don’t seem to be affected.

Note that I have an ASUS not Lenovo and still affected. The problem is with the recent versions themselves.


Generally Speaking

So, the common advice here is to install the latest version on our laptop manufacturer’s site, not on!

This tip is not new tip, it’s written in Synaptics driver download page itself:


The Synaptics device driver is customized to meet the specific requirements of your device manufacturer. To ensure that you get the appropriate device driver for your system, download your Synaptics device driver from your system manufacturer’s support website.


Getting To The Point

The new important note though, is to pick a version that is earlier than, even if that version is available on your laptop manufacturer’s page.

    I never upgrade anything when I’m forced to use Windows, however, I have the leak in Windows, but ubuntu seems to manage memory better for the application (and just in general….the linux kernel is smart that way). Thanks for posting this. I will have to check out my driver version and see if I can downgrade or something. This has been a huge PITD lately!

    Thanks for you tip !! I notice this problem Sometime it took 750mb, i end up disabling the sinaptics program on startup. But another problem appeared, the tap function (which i hate) became more annoying than the memory leak !! Hope this driver version cures the leak problem.
