Hi Jack, I did one more experiment i checked the original resolution and original touchscreen config without any change That is 320x240 and touch ABS_X=800, ABS_Y=480 This also has touch shifted by 90 deg and the image comes to only 75 % of the screen (which is i think ok considering the resolution)
So i tried to change the touch to X=320, Y=240 in 320x240 res. and the touch sensitive area decreased to top right corner of the screen Can u infer anything from this, i am kinda confused. thanks and regards Manoj On May 24, 12:36 pm, "Jacky.Seraph Mun" <jackyser...@gmail.com> wrote: > Hi Manoj, > > If you made it by changing in framebuffer device, you may also have to > change the touch pad abs size accordingly.
