Dual screen and Macbook



Hello,

I'm trying to get dual screen working on my macbook (Debian sid). But it
doesn't work after further different configuration.

With the attached configuration, X crash :
(II) intel(0): Kernel reported 104960 total, 1 used
(II) intel(0): I830CheckAvailableMemory: 419836 kB available
(==) intel(0): VideoRam: 262144 KB
(II) intel(0): Attempting memory allocation with tiled buffers and
               large DRI memory manager reservation:
(WW) intel(0): xf86AllocateGARTMemory: allocation of 10 pages failed
        (Cannot allocate memory)
(II) intel(1): Allocating 0 scanlines for pixmap cache

Fatal server error:

lspci | egrep -i 'vga|display|graphic'
00:02.0 VGA compatible controller: Intel Corporation Mobile

00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/940GML
Express Integrated Graphics Controller (rev 03)

I also tried to use both busID 02.0 and 02.1 without success.


Thanks for your help.
