Installing Meego IVI on a Lenovo s10-3t

The Lenovo S10-t is a very versatile device for Meego development as is has both a 10 inch touchscreen and a keyboard. This makes it an idea candidate for UX prototyping. Installing Meego IVI on the Lenovo S10-3t does require some extra work after installation.

Fixing X.org Issues

Touch Screen

Touch Coordinates Flipped Over Y-Axis

The official Russellville hardware requires that that Y axis be flipped for it's touch screen. This fix breaks the default calibration for the Lenovo S10-3t. To fix this issue add this to /etc/X11/xorg.conf or a file in /etc/X11/xorg.conf.d

 Section "InputClass"
     Identifier "evtouch touchscreen tsc2007"
     MatchIsTouchscreen "on"
     MatchDevicePath "/dev/input/event*"
     Driver "evtouch"
     Option "MinX" "80"
     Option "MinY" "80"
     Option "MaxX" "4095
     Option "MaxY" "4095"
 EndSection

Multi Screen Configuration

The Lenovo S10-3t has VGA out that can clone what is being displayed on the Lenovo touchscreen or provide an additional screen. The Intel graphics driver does not support "Zaphod Style" multi-head where each screen is assigned it's own X Display and it's own set of input devices. The Intel driver only "Merged FB" mode where the screen is interacted with as one large desktop. You will needs to re-calibrate your touch screen if you want the 2nd monitor to the left of the Lenovo touchscreen.

To create a 2nd display from the VGA port add this to your /etc/X11/xorg.conf
