Dual screen with T42p for projector

[r_2 at gmx.de]

Hello,

I get crazy with my setup of my IBM T42p for a connect to a projector.

here my hardware:
ATI Technologies Inc M10 NT [FireGL Mobility T2] (rev 80)

I tried the setup manually by configuring a second screen. I also tried the
proprietary driver.

In both cases stays my display black...

Anyone here who could help?

best regards,
Hans
