I try to use child's play on an old laptop (sony pcg-fx101) with qimo 2.0 installed.
With difficulties i managed to set an xorg with 1024*768.
When I run childsplay, the position of the mouse cursor is a few centimetres up and left from the position of the display.
In fact the display of childsplay is centered with a 3 centimetres black border around, and for the mouse cursor it is like the display was on the top left of screen,
then I have a 3 centimetres gap between the mouse cursor and the button I want to use, if i want to click on "connexion" for exemple, I have to position my mousse 3 cm left and up the displayed button
I am not sure I am clear enough and sorry for my bad English (mostly home French translation)
