I have installed a touch screen film which is connected via USB and it is recognized as a mouse device.
Hence, I can not swipe on a web page. It clicks and selects or clicks and drags something on the screen when I try to swipe.
There are questions and answers that didn't help my case:
- On what level is touch screen support implemented in Linux?
- Touchscreen is being recognized as a mouse in Arch Linux--how can I enable multi-touch with it and get it recognized as a touch screen?
My original problem description is here.
So, who is responsible for recognizing the input device as a mouse or a touch screen, OS or the app? So where should I search for the solution?
Searches and notes to myself
With the help of this forum thread (with a little bit changes), I could make
ts_test work. I calibrated the touch screen, draw a circle on the screen, etc.
Now what? The web browser I am using still selects some text instead of scrolling in the page.
Someone says "The application should use the input device directly" and someone other says "Application has nothing to do with the input device directly".
Should I edit the xorg.conf to emulate scroll event just because my application (Midori, the web browser in this case) can not use "the touch screen", or an Android phone does the same thing already?
How does an application get the mouse events in the first place? By opening the device file (
/dev/input/event*) by itself or somehow from Xorg server? If the application handles device file itself, how could Xorg server possibly emulate the mouse scrolling stuff?
If application is listening the Xorg server for the mouse/touch-multitouch/whatever events, than the application should be written these mouse/touch/whatever events in mind and Xorg should have an entry that we say "Hey, Xorg, the device you see in
/etc/input/event0 is a touch screen. When you get physical signals from it, tell the applications about the touch events."
