Hi Manoj,
If you made it by changing in framebuffer device, you may also have to
change the touch pad abs size accordingly. So you have to take a look
at the driver of touchscreen, which is usually located in
drivers/input/touchscreen/xxx-ts.c
where it defined the touch pad abs size in the __init_xxx_probe() function.
input_set_abs_params(ts->dev, ABS_X, 0,
/*CONFIG_TOUCHSCREEN_SIZE_WIDTH*/, 0, 0);
input_set_abs_params(ts->dev, ABS_Y, 0,
/*CONFIG_TOUCHSCREEN_SIZE_HEIGHT*/, 0, 0);
Then you need to change the the abs_x and abs_y according to the
change in your screen resolution. e.g. if you screen resolution is
changed from 320x240 to 240x320, your new touch width size should be
old_TOUCHSCREEN_SIZE_WIDTH * 240 / 320 and old_TOUCHSCREEN_SIZE_HEIGHT
* 320 / 240 for new height.
Hopefully, it can solve your problem.
