Fedora 6 video messed up

[siddallg]

I just installed Fedora 6 on my IMac 20" Intel machine. The install went great but when the setup welcome screen comes up I cannot see it. I get a blue screen with lines all the way across. I can move the mouse and affect the screen but since I can't read what is there it does me no good. I think it has to do with the default settings in Fedora being to high.

Can someone tell me how to change this or let me know if anyone has had a similar problem.

Thanks!

Here is what you need to do.

1. Boot FC-6 into single user mode. Right after you start the VM and before FC-6 start booting, there should be a couple of seconds delay. You need to hit a key, any key, to get into the GRUB menu. At the GRUB menu, select the kernel you want to boot then hit the 'a' key. It should show you a boot option line similar to this:
Grub append> ro root=LABEL=/ rhgb quiet
Now add the word single at the end
Grub append> ro root=LABEL=/ rhgb quiet single
Now hit the enter key to boot.

2. Once in the single user mode you don't have the GUI interface and you are root so be careful.

3. Edit (I use vi) the file /etc/X11/xorg.conf

4. Locate the Screen section and add a Modes line at the end of the Display subsection. It should look like this:

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

5. Save the file, restart FC-6, and you should be ok.
