This is another post in the numerous questions of "how to connect ubuntu to my TV". However, previous answers did not cover my scenario.
SO, to start with, I do not have nVidia / descrete graphics in my laptop (Dell Latitude E6220). I have the Sandybridge Intel chipset.
If I connect my laptop to my TV via HDMI (it is HDMI on laptop to a DVI connector on TV), Ubuntu fails to detect the screen, despite efforts such as rebooting with TV attached and running
xrandr --query. xrandr simply returns that the HDMI connection is "disconnected".
At this point, a fair assumption would be to say the HDMI port on laptop or TV is faulty. Not the case. I can connect the laptop to a monitor (also HDMI --> DVI) and a signal is present as expected. I can connect my Raspbery Pi to the TV and a signal is present as expected, ruling out faults at all connection points. It seems that there is simply something in Ubuntu that can't handle my TV.
So the question is:
What can I look at on the Pi that I can convert to be suitable information for the dell?
It seems odd that a severely stripped down distro can handle the TV (it is an old-ish Phillips "FlatTV" LCD) and a full Ubuntu install can't.
Out of the box utilitues would be preferable, as the pi is not wifi (running wheezy) and my TV has no network connection near by.
