I've searched Google, but haven't found any answer to this. I'm thinking about getting the Logitech T650 wireless touchpad as a replacement for my old mouse. (More information: http://www.logitech.com/en-us/product/touchpad-t650)

The device is targetted toward Windows 8. My question is, will this work under Ubuntu 12.10. And in particular, will the multitouch gestures work?

    It works with some gestures (I can move the mouse, scroll windows with 2 fingers and open/close the dash with 3 fingers). But the click (tab) doesn't work :-(

As of Feb 19, 2014 there is a new firmware update on the Logitech site that enhances out of the box gestures support for this touchpad. The firmware update process requires a windows box, but once it is done you can use the touchpad on Linux with the enhanced features without any extra software.

Here is the link: http://www.logitech.com/en-us/support/touchpad-t650?section=downloads&crid=398&bit=32&osid=14&softwareid=11370

    I upgraded my T650 to that firmware and it works now perfectly under linux (tap on click, 2 finger scroll, 2 finger right click, etc). I hope the word will spread.

So I just bought the t650 today and with the help of xev I was able to figure out how to get all of the button presses. I have not tried to map any buttons to specific functions but as far as I can tell here are the default mappings. As of yet I have not found a solution to tapping registering as a click. :-(

Button 1 (Left-click): This occurs whenever the touchpad is pressed down with 1 or 2 fingers so that either the front right and/or front left foot is pressed. Sole exception is when a single finger is pressed above the right foot.

Button 2 (Right-click): This occurs whenever the touchpad has a finger placed above the right foot and either front foot is depressed.

Button 3 (Middle-click): This occurs like a left-click event but 3 fingers are used to press the touchpad.

Button 4 & 5 (scroll-wheel): Button 4 occurs when two fingers are slid upward on the touchpad and button 5 when two fingers are slid downward.

Button 6 & 7 : Button 6 occurs when two fingers are slid to the left on the touchpad and button 7 when two fingers are slid to the right.

Button 8 & 9 : Button 8 occurs when three fingers are slid to the left and button 9 occurs when three fingers are slid to the right.

Of course moving one finger over the touchpad moves the mouse on-screen. I also found that moving three fingers up on the touchpad is the same as pressing the super (windows) key.

So that's what I found and I hope it is helpful to anyone who uses the t650.

Edit: This was taken almost verbatim from a review on Amazon.

  • Let us know if you ever figure out how to get tap to click working. :(

  • It's also worth mentioning that 3-Fingers-Swipe-Up triggers a Windows-Key press to be sent (in unity this will open up the launcher/search filter) and 3-Fingers-Swipe-Down triggers a Windows-D keypress. In windows this will 'Show desktop', but in Ubuntu does nothing that I can see, at least by default.

I'm using T650 on Ubuntu 13.04 (title) and found next gestures:

This basic functions works by default.

1.Mouse-left: Click touchpad.

2.Mouse-right: Click touchpad from right bottom corner.

3.Mouse-mid: Tap with three fingers.

4.Scroll-vertical: Slide two fingers up or down.

5.Scroll-horizontal: Slide two fingers left or right.

6.Open unity search (same as Super-button): Swipe three fingers up.

Next gestures are not defined by default. You can define them example as 'Keyboard shortcuts'. A custom keyboard shortcut can be almost anything. If you do it this way select the shortcut you want define it will ask for 'new accelerator' and then do the motion.

Gesture - System recognized keyboard button.

7.Three fingers swipe down: Super + D

8.One finger swipe from left edge: Ctrl + Super + Backspace

9.One finger swipe from top edge: Ctrl + Super + TouchpadOff

10.One finger swipe from right edge: Alt + Super + TouchpadOff

Next gestures don't work (as on Windows 8):

Left click as Tap. Spread or pinch with two fingers (zoom). Three fingers swipe left or right. Four fingers swipe up or down. Four fingers swipe left or right.

I think this is still quite useful touchpad even you can't use all gestures as on Windows 8 where it was designed for. Either configuring those extra gestures I listed isn't too easy.

Good news and bad. Yes, it does work on Linux but, because the Logitech T650 is made specifically for Windows, (unless I've been missing something) it is actually a very limited device (doesn't recognize "tap", etc.). As already stated, it does have some basic gestures like 2-finger scrolling and fwd/back for the browser.

If you are going to spend the money, (IMO) it's better spent on an Apple Magic Trackpad. You lose the built-in rechargable battery but you gain a large number of functions.

  • The firmware update mentioned above adds more advanced gestures. Jul 28, 2015 at 19:27

You can find some useful information at this url http://cmattoon.com/articles/logitech-t650-ubuntu

There you can sea what works and what doesn't work at the moment at Linux. Some gestures work and the mechanical click also works, but clicking by tabbing for example doesn't work.

For everything to work, a firmware upgrade might be needed. It involves a Windows computer and is unfortunately not as straightforward as downloading the firmware from the Logitech website and installing it, although that's what Logitech wants you to believe.

I spend a couple of hours trying to figure everything out, but finally found an answer in a thread in Logitech support forum (it's the answer by AndyCalling at 03-29-2014 07:52 PM).

By the way, I'd recommend using the brilliant Solaar to manage Unifying Receiver and connected devices.

I believe many of these answers may be outdated, in terms of requiring an additional firmware download. I've used the Logitech T650, which I purchased in 2017, with the following Ubuntu distros, and it has worked fine without any additional downloads:

  • KDE Neon 18 - 22
  • Pop!_OS 19 - 22
  • Kubuntu 19.04
  • Lubuntu 18.04
  • Budgie 18.04
  • MATE 19.04

One caveat: In the KDE desktops (Neon/Kubuntu/Lubuntu), tapping-as-click and "natural scrolling" are not enabled by default; you must do so in the touchpad settings. Unfortunately, the setting doesn't seem to be persistent (and in some cases it won't even let you set it via the GUI), so I do it via bash alias:

alias xinput.='xinput set-prop "Logitech Rechargeable Touchpad T650" "libinput Natural Scrolling Enabled" 1; xinput set-prop "Logitech Rechargeable Touchpad T650" "libinput Tapping Enabled" 1;'

(If for some reason this doesn't work, you can do it interactively, via the sequence

xinput # look for your device number, e.g. 12
xinput list-props 12 # look for the numbers for the tapping-enabled property
xinput set-prop 12 290 1 # set the property

Note that the numbers are not consistent between sessions, so using the named properties, as in the alias example above, is preferred.

2023 Update - Many distros have moved to Wayland. Support for the T650 is fine in Wayland, and tap-to-click seems to work by default. However, the xinput scripts above will no longer apply in Wayland.
