Thanks! The logs show that both 1280x800 and 1360x768 are detected as valid modes, and the X server chooses 1280x800 as the preferred mode, which also works fine. However, gnome-settings-daemon (if turn_on_external_monitors_at_startup is true) forces the 1360x786 mode which does not work.

I am not sure if the driver is at fault for exposing a non-supported mode of 1360x786 (although the kernel detects that the LCD panel size is 1280x800 pixels), or if it is wrong of gnome-settings-daemon to select a non-preferred mode. Or both...
