FC12 -- video resolution problems

just did a FC12 install on my notebook, blowing away my Centos 5.3
install. Big step up.
This is on a HP nc2400 that has the Intel 945M video. It comes up with
only 800x600 resolution.
So I installed system-config-display and configured the monitor
manually to be LCD 1280x1024, but selected only 1024x768.
I logged out and logged in, and I came up in 1024x768 video. I then
pressed <FN-f4> to switch to my external LCD monitor, and things
went a bit screwy. I should point out that my monitor is on a Belkin
KVM. But this has always worked in Centos.
My situation right now is that the system is running both internal and
external, and pressing <FN-f4> is not getting it to roll through
internal, both, external, internal, etc. as it 'use to'.
If I power up with the external disconnected, I come up in 1024x768 and
then if I plug the external in, it is not sized properly, like it is
only 800x600 and thus you only see the center of the screen and only
the background, not the running tasks.
If I boot up with the external plugged in, the video is 800x600 for
both internal and external, and I cannot roll through the modes.
So what is going on here and how can I get things working
I have the same situation, and used the xrandr script which Marko
posted a couple of weeks ago. This turns off the laptop screen on
startup, BUT anything which was on the laptopp screen gets "lost" ie, I
can't refer to anything which was in the trays. If I then click on the
cashew on the external screen & hit "zoom out", it shows me 2
screen images, the one I am using on the external screen (with the
"blue blob"background), the other which appears to be the last laptop
image with a plain blue screen.
My previous F11 installation used to have the same image on both
screens, which I could "auto config" on my external screen to get it to
full screen & Fn-f5(Toshiba) would cycle happily throught the
So far, I've not found an answer!
Have you filed a bug report? If not, I think it is time to do it....
