Question x window error on FC8 X86_64

after installing FC8 / updating system i'm trying to get into multi user mode, i am getting the following error message:

(ww) AST (0): Failed to set up write-combining range (0xfd000000, 0x800000)

i've tried changing from 800x600 / millions of colors to 640x480 / thousands but that didn't work.

any suggestions on how to get this fixed?

i should mention that the graphics worked correctly during setup, so i'm guessing that one of the udates is what screwed it up.

Thumbs down Similar problem?

Hello everybody, I am getting a very similar problem to this.

I had trouble installing Fedora 8. I had to add the vesa tag to the install command so that I could get a graphical installer, and I don't seem to be able to get rid of it now!

I have installed the Livna repository package successfully, proved since I could download gstreamer-plugins-bad and vlc. I have run the command yum install kmod-nvidia, but when I try to enable it using /usr/sbin/nvidia-config-display enable and restart X server (Ctrl+Alt+Backspace), X fails to boot up and I am forced to modify the xorg.conf file so that the driver reads vesa again...

I am using an Nvidia Geforce 8800 Ultra (EVGA SuperClocked edition) and Fedora 8 x86_64. Your comments will be much appreciated.

Hi Drick,
This failed message looks like the BIOS didn't configure the range as write-combined. The AST2000 driver should still work properly even the BIOS didn't enable the framebuffer as write-combined except for the performance suffered. Is there any problems while load AST2000 driver?
I'm an engineer from ASPEED Technology Inc., if you still met problems while load AST2000 driver, please send the xorg.0.log and xorg.conf to me. My email is
