Recently updated my laptop to Fedora 16. Fedora 16 is not detecting
my
second, external, monitor. The Monitor connects with an HDMI connector
or a DVI connector through a USB docking station. Connecting it either
way does not make a difference. What is strange is that during the boot
process, the system will display the flash screen on the second monitor.
There was a bug filed about this before Fedora 15 was released. Does
this bug still exist in Fedora 16? Does anyone know if any work has been
done on it? The bug deals with the Intel Sandybridge chipset. Note that
the laptop screen works fine.

Same problem here, no resolution that I have seen. Plenty of bugs open
in Fedora complaining of this and related issues:

Love to have some attention on this but I can only guess that not
everyone is seeing this. It's the only major usability issue I have
with Fedora these days but it's a big one.
I work around the issue by using the keyboard shortcut to toggle to the
mirrored mode and then once the ext display is up, I can turn off LVDS
and fix the resolution.
In related news, you might find that once this is working, it fails to
wake up after suspend and you have to do the dance again.
