Right click?
How do I configure right click to work, either two finger or long press is sufficient for me.
I tried adding these lines
Option "EmulateThirdButton" "1"
Option "EmulateThirdButtonTimeout" "750"
Option "EmulateThirdButtonMoveThreshold" "30"
into the same section statement as the calibration data from xinput_calibrator
but longpress does nothing.
There are multiple reasons why this does not work right. Touchscreen input has a lot of jitter and I'm not doing anything to reduce it in the driver. So, a "long" click may instead be recognized as a drag or multiple clicks. I'll see if finger tracking can be tuned a little.
I've had multitouch working occasionally, which may also be used to emulate second and third button clicks.
I would be happy with two finger click! Or long press, anything really.
Might having the correct resolution in the firmware, and not needing xinput calibration help with the jitter?
Good question. I think it will surely help with touch detection close to the edges, but jitter also affects finger tracking, and that happens before scaling. Guess I need to check how other drivers do it.
In any case, finding out the correct dimensions is still a good idea.
