Hello,
I'm facing to a problem with DirectFB and tslib module linear which
doesn't work.
I built tslib with --enable-debug to see if touchscreen works.
I calibrate my touchscreen with ts_calibrate and get the following settings:
# cat /etc/pointercal
-1265 5527 632612 -3622 1468 9748670 65536
Then if I launch a test application it works, I can see graphics on the
screen and I see touch in debug console and icons moving on the target
screen too.
# cat /etc/ts.conf
module_raw input
#module pthres pmin=1
#module variance delta=30
#module dejitter delta=100
#module linear
# df_input &

When I enable coordinates linearization like this, touchscreen stop
working and I see no messages from tslib debug in console.
# cat /etc/ts.conf

I noticed some weird messages loading modules, I verified files
permissions but I have no more ideas about what to do now
I also tried applying patch from syrjala without success

What is going wrong ?
TIA
