Well, that was an "official fix" by Fedora to Nvidia-type preupgrade ...
Have a live cd or an installation cd around in case you need it to
fix something because the system becomes unbootable.
Write/remember how to start it in a rescue mode or single user mode;
how to get to root prompt, mount any partition, chroot,
modify a file, execute something, rebuild your primary (MBR) bootloader, etc.
The latest Fedora live-cd is good for it. Knoppix as well.
Let's do the following:
- leave the kernel line options as before (that is xdriver=vesa nomodeset)
# mv /etc/X11/xorg.conf /etc/X11/xorg.conf-old
add new one with this content (just copy/paste, verify once more, write/quit)
# vi /etc/X11/xorg.conf
Identifier "Configured Video Device"
Identifier "Configured Monitor"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
- make a backup for future needs (it will come handy in emergency)
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf-vesa
- if the system becomes unbootable/graphics unstable, restore to your old
config file with nvidia driver
# cp /etc/X11/xorg.conf-fedora12 /etc/X11/xorg.conf
- reboot to your F12 kernel
