Hi,
Maybe try different device (e.g. /dev/input/event0). AFAIR it should be like
this for example:
... -plugin tslib:/dev/input/event0
or instead of adding this as command line argument it can be set as environment
variable:
export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0
Yes, that fixed it, thanks. I used tslib:/dev/input/touchscreen0

I finally got QT5 to build for my i.MX6Q SabreLite. I'm able
to run the cinematic demo, but the touch screen isn't working.
Here's what I get:
root@sabrelite:~# Qt5_CinematicExperience -platform eglfs -plugin tslib
evdevtouch: Using device /dev/input/event1
min X: 0 max X: 0
min Y: 0 max Y: 0
min pressure: 0 max pressure: 4095
device name: tsc2004
EGLFS: Unable to query physical screen size, defaulting to 100 dpi.
EGLFS: To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and
QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
QTsLibMouseHandler "tslib" ""
Protocol type A
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
Notice that the touch window is 0x0. I know the touch is set up
properly and calibrated as I've run the ts_* programs as well as
X11 and QT4.
How do I get the touch screen working with QT5?
BTW, the demo reports being able to display a screaming 177FPS!
Does that make sense?
