Touch screen: Right click should be emulated by long press, like under Windows 8 and Android

At the moment, XMir still handles input directly with evdev. This means input bugs are not Mir bugs yet.

Note that the right click is very important, many applications use it for essential functions, like Thunderbird, Nautilus, ...

Adding mousetweaks as the mouse functionality of "Universal Access" is implemented by mousetweaks.

It seems that the right-click emulation of mousetweaks only works with a mouse and not with a touchscreen.

Status changed to 'Confirmed' because the bug affects multiple users.

Also note that the right-click emulation of Universal Access only reveals the right-click menu after releasing the button, whereas under Android or Windows 8 the menu already pops up while long pressing. The latter gives the user the feedback that he has pressed long enough, and as it is also established as "standard" (two other operating systems use it) we should do it this way.

The right click on the touch-operated Ubuntu Desktop is not completely unimplemented. Besides the possibility of using the right-click emulation of Onboard one can right-click by holding one finger on the place where one wants to right click, and while holding the finger down tapping with another finger on an arbitrary place of the touch screen and after that sliding the held down first finger through the context menu to the desired item and releasing there, which leads to the item being selected. It works on the standard (in my case Unity) desktop and even in XBMC.

This gesture is rather awkward and far from intuitive to find without any instructions (see the time between this comment and my creation of the touch screen/convertible Blueprint to which this bug is linked), especially also where Android and Windows 8 use a long press as right click, and the Ubuntu Desktop is usually installed as an alternative operating system on machines which are originally supplied with Windows or Android and so conserving operation schemes from these systems makes switching over to Ubuntu much easier.

#7 not working here (13.04 on Samsung 700T). I seem to remember twofing had that gesture. Are you sure you don't have that installed?

I have never heard this name, and there is neitrher a package named twofing (or similar) installed nor is there such package available.

I have found twofing at http://plippo.de/p/twofing.htm. It is very promissing but they say that it only works on the Eee PC T101MT with eGalax touchscreen and I have the Lenovo Thinpad Twist with Atmel touchscreen.

I have followe dthe instructions of the first comment (Phil) on http://www.linlap.com/lenovo_thinkpad_twist, especially activated the Wacom support. Perhaps this changes things in available gestures.

Yes, the right-click gesture of comment #7 comes from the Wacom driver. If I remove /etc/X11/xorg.conf.d/50-wacom.conf again (or the "Atmel" in it) then the gesture goes away and I get the three- and four-finger gestures back.

Kudos to getting right-click behaviour like in Windows/Android. I manage to get a near to natural timing of the click using .22sec as the secondary click timing (using dconf). This behaviour is still really unnatural because you never know when you get it right until you lift up the finger.
I know you developers work really hard patching up stuff and writing new and cleaner code, but touchscreens have been out for a while and this elemental behaviour has not been address yet...

btw, I'm on an Acer V7 running Ubuntu 14.04 64bit (ELAN touchscreen)

Thanks for your work and I hope we get a fix real soon!

The click and hold to simulate a right click used to send the virtual right click before button release until march 2010. Changes in the X server forced the mousetweaks developer to move the virtual right click after the button release because as far as I understand, the X server stopped accepting virtual right clicks if the left mouse button had not been released. I don't know how the current X server would behave about this.

Anyway, as far as I have been told, a real right click simulation by a left click and hold should probably be implemented at a deeper layer than mousetweaks. Another aspect for example making problems is that mousetweaks is not able to discard the real left button down before creating the virtual right click. One of the consequences is that it is not possible to perform a virtual right click on a multiple selection as the real left mouse click preceding the virtual right click deselects the items.

By the way, mousetweaks tried to implement some kind of feedback to indicate when the user has hold the left mouse button long enough to issue the simulated right click: the pointer should fill up with a different color. However, this does not work reliably.

Guys,

In Ubuntu, there is a huge problem in the way touchscreen works. Only chrome has correctly implemented the functionalities. All the other applications have a poor user experience. Maybe you can discuss with someone from Google and try to replicate that, system-wide. I have a Huawei Matebook and because of this behaviour, I switch to windows from time to time :)

Kind regards,
