This is not quite a guide but hopefully gives a couple of useful hints on how to use LINX 8 more effectively in desktop mode.
1) Install touchmouserpointer (search web) . Turns on a trackpad emulator (like on a laptop), and gives a mouse pointer. Gives you much more precise control over desktop, instead of trying to touch very small icons/checkboxes etc.
You can easily flip-flop from w8 touch mode trackpad mode.
2) enable standard keyboard (numbers along top row) . You have to go to PC settings, keyboard settings etc. to do this.
3) install teamviewer or splashtop (my personal preference). Then you can take control of tablet via a laptop or PC and do configuration changes more easily.
