I have tried almost every imaginable option I could find online to put in the 10-evdev.conf file in the xorg.conf.d directory so as to disable the dragging action of my touchscreen (eGalax Inc. Touch) but I have not been able to. The touchscreen is recognized as a tablet device but I can live with that. If I give some Options such as Option "Ignore" "on" under the following section in 10-evdev.conf then it works (meaning, it disables the touchscreen). If I do the same under the touchscreen catchall, it does not work! Also, in the xorg log, I can see that it is recognized as a tablet (I believe this is a bug in the kernel but it really doesn't matter as long as I can configure the touchscreen and have it working properly)
Section "InputClass"
Identifier "evdev tablet catchall
MatchIsTablet "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
EndSection
Now, my problem is that no matter what Option I've tried, I am not able to disable dragging. If I touch the screen and drag my finger across the screen, it draws a rectangle or actually drags the icons on the desktop. All I need from the touchscreen is click (tap) functionality since I'm going to be using is as a kiosk. Can anyone give me the right configuration to disable dragging? Thanks Nahom
