Hi. I know this is not the answer you're looking for, but if you have eglfs, why go with linuxfb?

Andrei Pushkin

@Leonardo Hi. I use specific hardware Qt patches, that work only with linuxfb

hi @Andrei-Pushkin
I think I'm having the same problem as you concerning linuxfb and the rotation of my touchscreen.
Did you find a solution to it ?

@Andrei-Pushkin I had a problem to load touchscreen on my Qt 4.8. I solved it, loading the program with: WS_MOUSE_PROTO=linuxinput:$TSLIB_TSDEVICE $MY_APP &

Using "WS_MOUSE_PROTO=tslib" does not work for me

@Andrei-Pushkin I'm with the same problem. But, My touch is not working in tslib (ts_calibrate or ts_test). If I run the evtest, it works perfectly. Did you use some adicional package in your yocto conf (local.conf) file ?
