Modes from LCD TV not read - intel 2.2.0

Sun Dec 9 02:20:58 PST 2007

Hi,

I'm trying to connect an LCD TV to the VGA output of my macbook (intel
945GM). Somehow X does not pick up the EDID information from the TV and
xrandr lists the same modes for the laptop panel and the TV. Among these
the TV only accepts 1024x768.

$ xrandr 
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 3200 x 1080
VGA connected 1280x800+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
   1280x800       60.0* 
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis)
286mm x 179mm
   1280x800       59.9*+   60.0  
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  

It worked once, the log then showed that the modes had indeed been read
from EDID, but ever since it has failed the same way.

I'm using the intel driver 2.2.0 and the server 1.4.1 from Debian.

I attach my configuration and log.
Thanks
