           Summary: Xorg startup resolution is not the preferred

Xorg log

When X starts and i am greeted with the login manager (GDM), the resolution is
not set at 1440x900 which is default and best resolution for my samsumg 19" LCD
monitor (wide). It appears to be 1280x720 which is the default resolution of my
plasma TV that is plugged on the first connector (maybe it's setting the
default resolution of the device plugged on the first connector?).

I have to plug the TV on the first connector because sound only outputs on the
first one (should output on both as reported on
https://bugs.freedesktop.org/show_bug.cgi?id=27588). If i connect the samsung
LCD monitor on the first connector (DVI-0) the default resolution is detected
as 1440x900 as expected. To my understanding it should detect 1440x900
independently of the connector the device is plugged.

Here is the xrandr output:
