1950GT AGP full QE/CI support but when i start a game Display is black!

[p_bateman]

I have a IPC 10.5.6 System with 10.5.6 Ati 1950GT AGP (7288) kext.

The Desktop is full QE/CI supported but when i start a game the Display is black and i hear gamesound only.

The first Device is a correctly Radeon 1950GT AGP and the second Device is unknown.

 

I have changed a DVI-Port and use a VGA-Cable but nothing works.
