Radeon 9200: DRI on one head and 2d on second head ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello

I'm trying to setup an ATI Redeon 9200 card for a multimedia PC.

The goal is to be able to connect a video projector on the DVI head
(screen 1) and the monitor on the main head (screen 0). And my kid
would be rather disapointed if he can no longer play with gltron on
the main screen, so I need a working DRI on the main head.

With Xfree 4.3.0, I am able to setup DRI on one head, *or* set up a
dual head (2 screens setup). 

But in the latter case, the DRI is disabled: Radeon driver does not
support DRI with dual head setup even if the NoAccel option is set in
the second Device.

IS this statement correct or did I miss something ?

So I was considering to set up a single head configuration for X on
the main head and set up a frame buffer on the second head. 

Thus I could use directly the -vo fbdev and display the video directly
on the second head without going through X.

Is that possible ? (OK, I'm drifting off-topic)

Does anyone have a pointer and how to set up a radeon frame buffer on
the second head ?

Thanks for any help.
