Forwarding a bug from a ubuntu user: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/376722 Bug description: With a LCD LG TV 19LS4D connected to the VGA port on a Sony VAIO vgn-sz1m, the EDID information is not detected. The EDID information is detected with the 2.4 version of the driver, but not with 2.6.3 and above (also tested with 2.7.99). This results in the native resolution of the external monitor (1440x900) not being available. The maximum is 1360x768. Since the internal LVDS has a native resolution of 1200x800, he needs to add SubSection "Display" Virtual 1680 1200 EndSubSection to the "Screen" section of xorg.conf in order to get the higher resolution even with the 2.4 driver.

I should add that while the 2.4 logs says that the driver version is 2.4.1, there are quite a number of patches from 2.4.x making it closer to 2.4.3 in practice: https://launchpad.net/ubuntu/+source/xserver-xorg-video-intel
hi Geir The root cause is your monitor is Digital monitor and not real analog display VGA. II) intel(0): EDID Version: 1.3 II) intel(0): Digital Display Input In our latest driver we guarantee monitor connected with VGA must be analog output by if (!edid_mon || DIGITAL(edid_mon->features.input_type) sentence. Your monitor is pluged by DVI-I VGA convert as bug #21632? Thanks Ma Ling

Pls open it if you need. Thanks Ma Ling
