tslib touch random mouse behaviour

Hi,

I have corss compiled tslib and Qt 4.5 for ARM and ported to board. I have
exported all the environment variable and try to run ts_calibrate, however
its working fine, I am able to generate pointercal file with the
calibration utility, after I run QT program, but when i touch the screen
mouse not come at the touch point, its flickr on the screen and touch
screen is not working.

I have run cat /dev/input/event0 and I am able to see random char. on the
screen, I also run evtest utility it also working.

After calibration, i run qt Application/demo and touch the screen, but
mouse flickr on th screen and its not setting at a point hence touch screen
not working. I have also added tslib cflags and ldfals while compileing QT
but still problem persist. 


could you please let me know the possible solutions why this behavior is
happening?

I read the forum and tried all the possible steps listed in this forum, now
I am looking a technical response, I am not able to understand what I am
doing wrong.

Look forward to hear from you soon.

regards,
miniarm

Tell us what is in the ts.conf file.

Also, which mini2440 and more importantly which touchscreen.

module pthres pmin=1
module variance delta=30
module dejitter delta=100
module linear

mini2440 1GB with 7inch screen. don't know why mouse flickr constantly
while ts_calibrate working fine.

My ts.conf is

module_raw input
module pthres pmin=1
#module variance delta=30
module dejitter delta=10
module linear

I am not using the 7" but I think these values from the Pengutronix BSP are
OK for the 7" screen.

If that doesn't help maybe show us all your ENVIRONMENT VARIABLES for Qt.
