Upon booting, when I should see the GRUB menu, my monitor simply says: "No optimum mode. Recommended mode: 1600*1200". If I wait for a short while, Ubuntu starts to boot and it reaches the desktop.

So I guess there is no video signal during that time, there's the grub menu but I cant see it and after the wait time everything is fine. I have the same problem when I log out for a short moment, before the log in screen is reached. and this also happens when i shut down ubuntu.

The VGA is an onboard NVIDIA GeForce 7025.
