It is not clear to me what is your problem, but I just got mine working. I am posting parts of my config file. Please pay atention to the red lines.
1: Had to add a line for the tablet:
Code:
# Xorg configuration created by livna-config-display
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Configured Mouse" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "tablet" "SendCoreEvents"
EndSection
2: I think your line should say "event4". Regarding the green options, those are suitble for my monitor, and I even have to check if are the correct settings now, but you may change to suit your needs:
Code:
Section "InputDevice"
Identifier "tablet"
Driver "wizardpen"
Option "Name" "UC-LOGIC Tablet WP8060U"
Option "Type" "stylus"
Option "USB" "on"
Option "Button1" "1"
Option "Button2" "1"
Option "Mode" "Absolute"
Option "Device" "/dev/input/event5
Option "SendCoreEvents" "true"
Option "TopX" "391"
Option "TopY" "1704"
Option "BottomX" "32701"
Option "BottomY" "29254"
Option "MaxX" "32701"
Option "MaxY" "29254"
Option "BottomZ" "1023"
Option "TopZ" "10"
EndSection
Thanks to the people who made this too easy.
