multi-touch interview questions
Top multi-touch frequently asked interview questions
My workstation with Ubuntu 12.04 is a MacBook Pro which supports a Multitouch Trackpad.
Unfortunately, I'm constantly accidentally triggering the three finger touch gesture to resize a window:
How can I disable this gesture?

Recently, I have upgraded from 13.04 to 13.10. First, I found problem in edge scrolling. After surfing in net about the problem I came to know that Ubuntu 13.10 has default two-finger scroll option enabled in Mouse and Touchpad setting. After unchecking two-finger scroll edge scrolling was enabled.
In windows, I have used both feature. How can I use both two finger scrolling and edge scrolling in Ubuntu 13.10 permanently so that the setting won't reset even after I restart, shutdown or suspend my laptop?

I can't find a way to modify the touchpad gestures Unity uses by default on Ubuntu 12.04/12.10.
Tried with Ginn, but it shows error subscribing to gestures and it seems because of Unity.
Is there a way of customize the trackpad gestures of Unity?

I have an ASUS Zenbook UX31a and multi touch gestures worked great on 12.10, but after I upgraded to 13.04 every gesture stopped working, except for 2, 3 and 4 finger taps (the 3 finger tapped changed function, though).
According to this comment on Launchpad the gestures were removed by design, but no other explanation is provided.
What is the reason for removing trackpad gestures?

I don't remember how but in 11.10 I had managed to find a few multitouch actions to be supporetd by some software.
Now I am using 12.04, Is there any way/application/workaround/plugin or anything that can provide me with multitouch gestures similar to mac or atleast near to it?
With synaptics I figured out that my touchpad supports 3finger control.
I am using a Samsung NP-RV509-A0GIN.

I'm not sure if Unity has a design problem. If the Launcher is hidden you can bring it to front by moving the mouse over the home button or hit the Super Key. So far, so good.
But what is on Tablet Devices with touch panel? Intuitively I would "click" in the corner to show the launcher, but a click will open the Dash.
How should that work on a touch device? Do I have to "drag" my finger into the corner? Will touch devices have a "menu button"? Will there be a gesture to show the launcher?

It is disabled (greyed out) in Mouse and Touchpad settings. Edge scrolling works though :) Tried many solutions available online but couldn't succeed.
My touchpad is
SynPS/2 Synaptics TouchPad

it used to be that tapping two fingers on the touchpad send a middle mouse click. Now it does a right click and three fingers now are the middle click. I really can't understand the change and think it is a bug or badly copied from Apple or something. The reasoning escapes me totally.
I use middle click to open links in a new tab in the browser all day and I rarely use right click (and I have a right mouse button below the touchpad, doh)
Tapping three fingers on my tiny EeePC touchpad is next to impossible so I want the old behavior.
I found:
synclient TapButtons2=2
synclient TapButtons3=3
but that did not work on 10.10
Does anyone know how to restore sane behavior?

I know that my touchpad is capable of it. I can enable glitch-free two-finger scrolling by running this script:
#! /bin/sh
synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1
synclient EmulateTwoFingerMinW=10
synclient EmulateTwoFingerMinZ=48
However, in the "Mouse" preferences GUI, the "two-finger scrolling" option is greyed out. It worked fine on my old laptop.
Here is the output of sudo lshw -sanitize, if it makes a difference.

I'm using a custom Touchégg multitouch gesture setup in Ubuntu 11.04 with a Magic Trackpad. Since the default gestures (such as 3-finger tap and drag to move windows, 4 finger tap to reveal the dash, etc.) are apparently hardcoded in Unity, I'm unable to assign any custom Touchégg actions to them, and some default gestures (that I don't intend to use much, if at all) occasionally mix up with my similar custom-assigned ones and get triggered by accident.
Is there a practical way (short of tweaking the uTouch source) to disable some of the default gestures? If not, pointers to parts of the code (perhaps in grail?) where the default gestures are defined, and help with tweaking would also be appreciated.

Multitouch seems to be working fine on Chromium out of the box, but not on Firefox. On Chromium, dragging a finger up or down the screen scrolls the screen as expected, but on Firefox, that gesture seems to be highlighting text. How can I get Firefox to play nice with multitouch gestures?
I'm running Ubuntu 14.04 on a Lenovo Yoga 2 11" convertible laptop.
Edit: I read the page here which says that touch capability is present but disabled in FF. But enabling them and restarting doesn't seem to have any effect--dragging one's finger across the screen still only selects text.

I got nice laptop with a touchscreen (HP Envy TM m7). It came pre-installed with Windows 8 and I promptly put Ubuntu on it. Due to some issues, 13.04 wouldn't work so I went with the 12.04.02 LTS instead.
The touchscreen worked out of the box when it comes to clicking, but I wonder if there is a way to add more tablet-like gestures such as 2-finger pinch zooming, or scrolling with a one-finger swipe, or cycling through open applications by swiping from the screen edge etc.
Google results are in most cases only concerned with touchpad gestures.
Here is the weird thing: Two-finger gestures work on the touchpad (e.g. the two-finger scrolling) and can be changed in the "Mouse and Touchpad" panel. Three-finger gestures such as pinch to maximize or Four-finger tap to open dash do only work on the touchscreen.
What I cannot seem to configure is two-finger scrolling on the touchscreen, as there is in general no settings panel for the touchscreen.

Where do I find those features? In Ubuntu there's only an option to enable Two-Finger-Scrolling.
