I've recently upgraded my F6 to F8. The install finished ok but when the

screen goes blank and never returns. There was no indication during the
setup that there was a problem with the video card (I installed using
the graphical installer by the way).
I'm a bit stumped because I can't really even look at any logs files or
anything because the screen goes blank before it finishes booting up to
Gnome. I tried maybe secure shelling in but that doesn't work either
because maybe ssh service might not be turned on by default or
something, not sure. I don't even know if the system finishes starting
other services or finishes other booting-up procedures because the
screen just goes pitch black just when the os starts turning on
services. I'm attempting to reinstall i rescue mode now but don't know
if this will help resolve the issue. Thanks in advance for any ideas.

When the system starts to boot, hit a key to bring up the Grub menu.
Use e for edit, and then use the arrow keys to highlight the kernel
line. Hit e to edit this line. If you put a 3 at the end of this
line, and hit b for boot, you will boot into run level 3. (there is
also an option you can remove so that you stay in the text mode the
entire boot, but I don't remember it right now - I normally boot
this machine that way. For me, the change would be from:
I don't think that will happen, the problem occurs when the
initialisation scripts begin, not when X begins.
Specifying 'vga=6' instead of 'vga=794' or similar _might_ help.
The problem may be related to one I reported against Taroon beta (yeah,
years ago) (it might have been nahant-beta, fewer years ago but still in
the far distant past).
The problem I had was at that point it does the i18n initialisation, and
clears the boot messages from the screen, all the way to the middle of a
line where some escape (screen control) sequence is printed in the
middle of the line. This occurs for me, now, with f8. On all occasions
I've seen it, it's been on Intel graphics.
To me, it seems possible that you have a different manifestation of the
same problem, presumably the kernel driver's mishandling an escape
sequence that should be okay.
It happens at that point, the script's loading a font, and since I'm
happy with the standard Kernel fond, I'm happy to turn that off. The
easiest way is to change SYSFONT in this file:
10:35 [summer@numbat ~]$ cat /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"
10:45 [summer@numbat ~]$
Doesn't matter what you change it to (deleting is okay, but changing it
shows it was changed), lower case is fine.
If you can't get a visible screen to do that on, here are some things to
try.\
1. Boot to runlevel 1. Edit the commandline as Karl described, entering
"1" instead of "3."
2. If that does not work, edit the line as above, and instead of "3"
type "init=/bin/bash" - this avoids all the initialisation, and gets you
in a shell script on a ro filesystem.
2.a You need to get the filesystem rw. Something like this:
# mount / -o remount,rw
2.b Edit /etc/sysconfig/i18n
# ex /etc/sysconfig/i18n -c /SYS/s=Y=y= -c :wq
2.c Get the filesystem to ro, just in case:
# mount / -o remount,ro
2.d reboot
# reboot
If you don't like the idea of gathering geek points that way, try your
rescue CD or install CD in or even in install mode - switch to tty2
_when you're in anaconda, any time before you repartition the disk, and
poke around. Unless you mount and chroot into the F system, the tools
available may be reduced functionally, but they are adequate.
