Thanks Ian,
I ran the calibrate many times, have the /etc/evtouch/calibrate file. I edited
your CF-19.fdi file and put in my figures from the evtouch config. Now how do I
get it to read that file?
Here is my evtouch/config
MINX="290"
MINY="101"
MAXX="3986"
MAXY="3618"
X0="5"
Y0="2"
X1="-2"
Y1="2"
X2="-5"
Y2="2"
X3="-2"
Y3="5"
X4="-1"
Y4="5"
X5="-1"
Y5="5"
X6="-3"
Y6="3"
X7="-4"
Y7="3"
X8="-3"
Y8="3"
And here is my cf-19.fdi
<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<device>
<match key="info.product" contains="TouchScreen">
<match key="info.capabilities" contains="input">

<merge key="input.x11_options.minx" type="string">290</merge>
<merge key="input.x11_options.miny" type="string">101</merge>
<merge key="input.x11_options.maxx" type="string">3986</merge>
