Fedora 17: How can I eliminate "Input Signal Out of Range" messages?

I have a HP Pavilion p6607c system which is now running Fedora 17 exclusively. The system has a widescreen LCD monitor which supports up to a 1600x900 screen resolution at a refresh rate of 60 Hz. Whenever I boot this system, or whenever I try to run some applications (such as games for my son), I see a message on-screen which basically states: "Input Signal Out of Range. Adjust your settings to 1600x900 at 60 Hz" (please bear with me as am I somewhat paraphrasing this as I have very poor vision because I am partially blind).

I saw this same issue when I used to run Ubuntu on this same system. Under Ubuntu I was able to solve this issue by changing an entry for "GRUB_GFXMODE" in /etc/default/grub.

I have the proprietary nVidia driver installed on this machine for the integrated nVidia GeForce 6150SE, nForce 430 VGA graphics card. Even before the installatin of the nVidia driver, this issue still occurred using the Nouveau driver.

In case it would be of any assistance, here are the contents of my /etc/X11/xorg.conf file:

        Depth       24

I have searched for a resolution to this issue, but almost all postings which I have found were for Fedora 12 and earlier.

thanks for any input which you can provide.

Take care.

For the GRUB_GFXMODE setting, try adding this line to /etc/default/grub


then rebuild your grub.cfg file by

grub2-mkconfig -o /boot/grub2/grub.cfg


Above might help with set an appropriate video mode during boot. I don't know about the other problem of applications and games switching to an unsupported video mode.
