Wierd Graphics Issue

[kimothy1987]

Hi. I got a strange problem with my computer. This happened a day after installing Fedora 10 with KDE 4.1.

Issue:
When i start or restart my computer my montior tells me it have no input signal. I don't se anything (no bios, grub, fedora starting) untill KDE 4.1 starts up and I'm at my desktop.

I canged settings in grub'm menu.lst so that windows would boot first, but i never get to see the windows loading or the desktop. At this point I was stuck. I had a system which would boot windows, but never give me a image on the screen. To solve this i got a really old matrox pci 2d card and startet up using that card. And i worked perfectly. Now I could see grub again, so i started up fedora again and changed in menu.lst to make it default again. Now i use my normal graphics card again.

I still have the same issue. While using my ATI Radeon HD2900PRO my screen is completely black until fedora starts up with kde 4.1.

I NEED HELP!

As I understand you're getting a "No input signal ..." screen instead of grub, and you're not able to boot Windows as well. Am I correct?

Can you post grub.conf/menu.lst on this thread.
