Intel 8xx series graphics card not well support KMS

1.What is kernel modesetting(KMS)?
Currently, most graphics modes are initialized during the X server startup. Kernel Modesetting (referred to as KMS hereafter) moves this process from the X server's DDX drivers to the kernel, and it enables several new features including:

* Improved Graphical Boot
* Faster fast user switching
* Seamless X server switching
* Graphical panic messages

Memory Management, while a separate feature in its own right, is included here because it is a requirement for Kernel Modesetting.

2.Fedora 11 enable this by default

3.However, Intel 8xx graphics card or earlier edition did not well support this. So KMS may produce several troubles.



4.how to find the informaiton of your video card?

>lspci | grep VGA



5.How to figure it out?

disable KMS.

To fix, disable kernel mode setting (KMS) by adding the following to the kernel parameters in /etc/grub.conf after "rhgb quiet" "nomodeset". But if you still want the graphical boot screen then add this also "vga=0x318".
