I have a Dell laptop, XPS M1330.
I had this problem with f12 originally but didn't go deeper with it.
Now I have updated the same system to f13 and experiment the same.
It has an hdmi-out connector and I'm trying to correctly configure it to send audio/video to hdmi only.
The connection is to a Panasonic 37" TV.
Audio is ok.
For video, after reading the tv specs I set these relevant parts in xorg.conf
Section "ServerLayout"
Identifier "Default Layout"

It works and sends audio/video only to the tv, while the laptop display remains black, but it seems that upper and lower rows of the screen are not shown...
For example I don't see the top and bottom main bars.
xdpyinfo shows:
screen #0:
dimensions: 1920x1080 pixels (650x366 millimeters)
resolution: 75x75 dots per inch
depths (7): 24, 1, 4, 8, 15, 16, 32
root window id: 0x15a
depth of root window: 24 planes
so it seems correct

I know that I'm using proprietary nvidia module and the question would be somehow offtopic, but probably it is not related (only) to the driver..
Anyway I could also try to use nouveau driver and see if the problem arises with it too...
In the mean time any suggestion?
When X Windows System starts, the tv shows the label
WIDE
1080p
So it seems it accepts the 1920x1080 resolution.
BTW: on laptop
cat /proc/cmdline shows:
ro root=UUID=f829ca09-552e-46ce-85bd-779da1c90d17 rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet rdblacklist=nouveau nomodeset elevator=deadline /dev/sda6
Thanks in advance,
