I've done more tests :
- Virtual size smaller than 2048 : neither 1600x800 nor 1280x1824 worked. I got the "low resolution" screen, and mtrr error in dmesg.
- Virtual size of the size of my LVDS : 1280x800, and no external screen connected. It didn't switch to gdm, and I just got the console login screen. No error on dmesg, but these errors in gdm log :

Parse error on line 48 of section Screen in file /etc/X11/xorg.conf
        "Virtual" is not a valid keyword in this section.
(EE) Problem parsing the config file
(EE) Error parsing the config file

Fatal server error:
no screens found

I haven't seen error about "Virtual" keyword when I got the external screen connected, so this may be normal.

I don't use the greed option anymore, but I use a new version of the intel driver that doesn't neet it : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/177492/comments/84
