Hi all !

 

I have a acer 7741g with core i5 and ATI Radeon 6550M.

I installed Lion successfully.

 

But when I put GraphicsEnabler to Yes, my internal screen come black after apple logo screen.

When I plug an external monitor (VGA), the computer detect it and OSX works fine with QE/CI (internal monitor stay black).

 

The problem is not EDID, as I replaced it : new edid is detected, and image is display on my 4/3 external screen with a resolution of 1600*900 (my internal screen is 16/9 1600*900). (I can change resolution from system preferences)

 

I tried different frame buffers (AtiConfig=...) but no one works for my internal screen.

 

I found this description of my graphic card :

And this topic seems interesting but I dont understand what to do in my case :

Can you help me ?

 

PS : Sorry for my bad english...
