Fedora 15: Black screen without nomodet

[vocongdanh]

I found a bug, it's due to light the screen, if I start not choose nomodet the screen is very dark, I use the setpci -s 00:02.0 F4.B=00 the screen back to normal, but when I restarted, which continued to setpci. How to fix this, thanks!

Not sure. Are you using Nouveau for your video driver?

[vocongdanh]

no, i do not have this

Before installing Nvidia drivers or anything special, make sure to do #yum -y update. This makes sure you have all the right stuff on board and up to date

If you use nomodeset, it does boot up, correct? (I ask because I've had issues where something else was going wrong, and I couldn't see it because during the time it was changing to the framebuffer the screen went black and the problem happened then.)
