tslib device support

[JesseGuoX]

Hi there, is there anyway to add support for tslib devices, I know tslib devices do not write functions in the kernel, is there another way to support it?

tslib should work. You should set the correct event file.

example for tslib:

TSLIB_TSDEVICE=/dev/input/event2

then

./framebuffer-vncserver -t /dev/input/event2 -v

https://manpages.ubuntu.com/manpages/trusty/man5/ts.conf.5.html

The tslib calibration file is not supported.

my touch device is /dev/input/ts2 , export TSLIB_TSDEVICE=/dev/input/ts2; framebuffer-vncserver -t /dev/input/ts2 -F 60 -v won't work.

Your comments have no details.
If you think that something is not working properly then show it in your log or in the program code.

I tested framebuffer-vncserver with QT application using tslib and there was no problem.

framebuffer-vncserver writes into /dev/input/eventX.
tslib is an application library which reads /dev/input/eventX
They are independent.

dataflow:

framebuffer-vncserver -> /dev/input/eventX

/dev/input/eventX -> tslib -> application

I'm sorry for my last comment.
I have two different devices with touch screen. One of the touchscreen node is /dev/input/event5, it is works fine with framebuffer-vncserver. The other device's touchscreen node is /dev/input/ts2 and it won't work properly.
The framebuffer-vncserver could not get the right range of the xy :

$ framebuffer-vncserver -F 60 -t /dev/input/ts2
