LinuxQuestions.org - SUCCESS: 3M Microtouch touchscreen in Ubuntu

After sinking about $250 into a touchscreen from an old airport self check-in, I finally got the thing working under Feisty.

First, I installed the driver:

Code:

sudo apt-get install xserver-xorg-input-microtouch

Then I had to put this into my /etc/X11/xorg.conf

Code:

Section "InputDevice"

        Identifier "TouchScreen"

        Driver "microtouch"

        Option "Type" "finger"

        Option "Device" "/dev/ttyS1"

        Option "ScreenNo" "0"

        #subtracting shifts cursor right

        #adding shifts cursor left

        Option "MinX" "150"            #left

        Option "MaxX" "16233"          #right

        #subtracting shifts cursor up

        #adding shifts cursor down

        Option "MaxY" "200"            #Bottom

        Option "MinY" "16483"          #Top

        Option "SendCoreEvents" "yes"

EndSection

Next, add the following to the serverlayout section

Code:

InputDevice "TouchScreen"

After all that, I had the resolution on the monitor set to a really poor setting, so I then changed the default depth in the screen section to a lower number which fixed the problem.

Code:

Section "Screen"

        Identifier      "Default Screen"

        Device          "ATI Technologies Inc 3D Rage II+ 215GTB [Mach64 GTB]"

        Monitor        "Generic Monitor"

        #This is where I made my change from 24

        DefaultDepth    16

        SubSection "Display"

                Depth          1

                Modes          "1024x768" "800x600" "640x480"

        EndSubSection

        SubSection "Display"

                Depth          4

                Modes          "1024x768" "800x600" "640x480"

        EndSubSection

        SubSection "Display"

                Depth          8

                Modes          "1024x768" "800x600" "640x480"

        EndSubSection

        SubSection "Display"

                Depth          15

                Modes          "1024x768" "800x600" "640x480"

        EndSubSection

        SubSection "Display"

                Depth          16

                Modes          "1024x768" "800x600" "640x480"

        EndSubSection

        SubSection "Display"

                Depth          24

                Modes          "1024x768" "800x600" "640x480"

        EndSubSection

EndSection

This tutorial was where I got most of my information, but I hope my notes help especially for ubuntu.
