I've got a Dell Precision M4600 laptop, running Fedora 17. Sometime
after kernel 3.7.9-104, the external VGA output no longer works.
If I boot with 3.7.9-104,with my projector attached, it is recognized.
If I boot with 3.8.4-102, external VGA devices are not recognized.
lspci:
01:00.0 VGA compatible controller: nVidia Corporation GF108 [Quadro
1000M] (rev a1)
(I've tried running the driver from nVidia, but that has screen
rendering problems, with blocks of random data instead of my normal
background pic)

/var/log/Xorg.0.log ought to show what's happening. Or 0 ... to 9.
'the driver from nvidia'? Which one? but perhaps you want to run nouveau?
------
The Xorg logs from the 3.7.9-104 kernel clearly show that the VGA is detected:
[ 48.288] (II) NOUVEAU(0): Printing probed modes for output VGA-1
[ 48.288] (II) NOUVEAU(0): Output VGA-1 connected
The Xorg logs from the 3.8.3-103 (and newer 3.8.4-102) kernels, show the driver believes the VGA is not connected:
[ 46.357] (II) NOUVEAU(0): Output VGA-1 disconnected
Starting to look like the driver was changed between 3.7 and 3.8 kernels?

I'm afraid this device is outside my comfort zone. nVidia say their
310.44 driver supports the Quadro 1000M, but I don't see packages for
that on the rpmfusion site. 304.88, which is there, is claimed to
support it too. Don't know nouveau.
