I have a Radeon Mobility M300 video card on an IBM T43 labtop.
I have this labtop on a docking station connected to a Dell screen.

SaX2 doesn't recognize my Dell screen, and so from the labtop commands I am unable to have the main screen on the Dell monitor and a secondary one on the labtop screen.

I would like to have (if possible) my primary desktop on the Dell Monitor and the secondary one on the labtop screen.

Can you please tell me what to install /update /configfure?

Thank you
