Screen Resolution in Fedora 13 on Intel i915 Chipset

[Samuel Kidman]

Hello

I'm having an issue increasing my screen resolution in Fedora Core 13. The
only resolution options available to me in System>Preferences>Monitors are
1024x768, 800x600, 848x480, and 640x480.

>From xorg.0.log:

[ 71408.317] (II) intel(0): Printing probed modes for output VGA1

I am certain the i915 chipset is capable of more modes than this, because I
had a much higher screen resolution at install. How come I'm not getting all
of the modes available on my video card?

This problem only started happening after I plugged my computer into my
HDTV- the screen resolution automatically adjusted to the new monitor, and
when I changed i tried to increase the screen resolution again, I had all of
the options that I should get but selecting one caused an error and my
screen resolution changed to what it is now (1024x768) and I have since been
unable to change it back.

Help!

Regards, Sam
