Enable Multitouch(two-fingers) on Synaptics trackpad on Linux

This could be your Trackpad

This could be your Trackpad

Very few people know that every synaptics trackpad supports multitouch and as long as your OS supports it  you can always use multitouch to enhance your computers interface. Apple has patented several UI design elements ,hence has inhibited Windows and Linux to come out with similar UI elements like pinch and zoom, scroll etc.

apt-get install  xserver-xorg-input-synaptics 

Now  edit your xorg.conf file

sudo vi /etc/X11/xorg.conf

find the input section

Section “InputDevice” Identifier “Synaptics Touchpad”

Add these lines in it

Option “HorizEdgeScroll” “on”

Option “VertEdgeScroll” “on”
Option “VertTwoFingerScroll” “on
Option “HorizTwoFingerScroll” “on”
Option “CornerCoasting” “on”
Option “PalmDetect” “on”

You only need a patched driver to enable multitouch features in synaptics. Download the latest driver from here

Download links (for XP/Vista 32/64-bit):
http://www.sendspace.com/file/9n9c6i
http://mihd.net/42vtopk

This driver is made from an outdated driver of synaptics. So you may have to uninstall your existing driver

  1. Go to Add-Remove Software. 
  2. Find and uninstall synaptic driver
  3. Reboot

Extract the zip file(touchpad_synaptics_v10.2.4_vistax32x64_xpx32x64_modded_build2.zip) to a folder

Install selected driver.

This driver is not signed. Hence windows will issue a warning. Do not install this driver on your production machine. This is a development build and using it may crash your system

Now you can  enable these 3 features on your Windows Desktop using Synaptic Options. Go to bottom right in your Windows taskbar to select synaptics tray icon or search synaptic in control panel. Then select Synaptic touchpad in Device Settings. 

  1. Multitouch scrolling : You will be able to scroll using 2/3 fingers. The scrolling is not as smooth as mac (shucks!!) but works equivalent to page up and page down. Here is how to enable it in Synaptics Options. You can configure what each direction will cause.
    Two finger Gestures -> Top/Bottom/Left/Right
  2. Chiral Motion : This technique is very useful for precise scrolling. Whenever you wish to scroll just slide two fingers downwards(or upwards) and then you can move your fingers in clockwise or anticlockwise order to continue scrolling.This is a much more precise way of scrolling but you need to get used to it. Here is how to enable it in Synaptics Options
    Virtual Scrolling -> Enable Chiral motion scrolling
  3. Momentum : This grants your mouse momentum so if you drag your mouse and leave it. It will travel some more distance depending on the speed of your drag. This is quite cool for some time, but very difficult to handle and impractical. Still somthing cooool to show off :). . Here is how to enable it in Synaptics Options
       Pointer Motion -> Momentum -> Enable Momentum
  4.  

 

UPDATE: The driver has not functioned for some laptops. It is suited only for some laptops. If you have installed this driver, do let us know in the comments if this worked for you. Thanks!!!

Power consumption to define the next generation in computation

The period between 2000 and 2004 had Intel and its rival AMD (Advanced Micro Devices) beefing up their silicon platters with more and more transistors. With Intel winning the GHz Race (http://www.zdnet.co.uk/tsearch/gigahertz+1ghz+barrier.htm).

Both Intel and AMD continued to push forward in their race to beat the 2Ghz. The main stream consumers suffered frequent system shutdowns owing to their molten cpus. It was not until the exploding athlon on Toms Hardware that AMD realized that they needed to get back to the drawing board. Out came the AMD64bit line of cpus. The Intel camp also were busy melting the silicon wafers.  Still the gigahertz race was on. The heated cpu cores from their prescot line of Pentium 4 processor showed the inevitable futility of the Gigahertz race. There was a big lull period during 2004 and 2005 during which both Intel and AMD couldnt push their processor speeds and ratings past the 4Ghz. That was when the giants realized that one core is retro and multi core is the new Pentium.

Putting more and more cores on a single die means more power consumption. Power efficient processor designs decreases the cost to run data centers and huge computing clouds. Given the fact that we would be running out of oil in the next few decades. Its onus own our part to decrease our energy consumption

Here is some of the recent developments of an economy conscious about power usage.

  • Apple to adopt Intel’s ultra-mobile PC platform : This is an exclusive report of Apple insider. A 1 Watt processor is going to bring a paradigm shift in the way we use computers. Something which is already shaken by the apple iPhone. It is going to make mobile platform as the main stay in computation.
  • Solid State Hard drives : These drives run at twice the speed with 10 times lower latency and more than 60% less power compared to top of the line hard disks of today. Mass adoption would hopefully bring the price down. Apple is already looking to put in their their mac book pro line of notebooks.
  • MIT Students run super computer using pedal power : A virtual nuclear fusion reaction was modelled on a super computer running for 20 minutes on bicycle power pedalled by 10 cyclists from MIT. I wonder how they have time for all these pet projects between course work
