Description Harlan Dy 2016-06-11 13:53:35 UTC 
evdev doesn't seem to work with long touch as right click. Even with Emulate3Buttons in the xorg.conf. When i long touch, it does nothing. Using Debian Jessie armhf running in chroot. Using evdev 2.10.3. Also how do I enable "drag scrolling"?
Comment 1 Peter Hutterer 2016-06-13 04:20:28 UTC 
couple of things here:
* emulate3buttons is for middle button emulation, you're looking for the "EmulateThirdButton" option
* that option only works for single-button devices, not for button-less devices. so for a touchscreen without physical buttons, this option won't do anything. when it was introduced the single-touch screens at the time would emulate a left mouse button press on touch but this isn't the case for real touch screens these days. We require gesture processing (and this includes hold-to-right-click) to be in the clients
* drag-scrolling must be implemented in the client

So the current behaviour is as expected, sorry.

Option "EmulateThirdButton" "1" doesn't work. So how do I enable right click on a multitouch display?

As I said in comment 1:
"* that option only works for single-button devices, not for button-less devices. so for a touchscreen without physical buttons, this option won't do anything."

evdev does not emulate right clicks on a multitouch display.
