I did my usual old “yum update” the other day and it hosed up my video upon reboot!
Never fear, it is a known problem, and has probably already been fixed by the time you read this.
But one thing I learned is that you should have akmod installed so the system will be smart and use a previous video driver if it fails. To do this, all I needed to do was:
yum install akmod-nvidia
then, on reboot, it was all working again.
[Update]
One thing to note is that when you do a yum update, make sure if there is a new kernel that there is a corresponding nvidia update for it! If not, then DO NOT yum update, and try again in a day or so. Eventually there will be a matching nvidia update and you are safe to update. Example:
Installing:
kernel x86_64 2.6.34.9-69.fc13 updates 22 M
kernel-devel x86_64 2.6.34.9-69.fc13 updates 6.4 M
Removing:
kernel x86_64 2.6.34.7-63.fc13 @updates 102 M
kernel-devel x86_64 2.6.34.7-63.fc13 @updates 23 M
Installing for dependencies:
kmod-nvidia-2.6.34.9-69.fc13.x86_64 x86_64 1:260.19.36-1.fc13.3 rpmfusion-nonfree-updates 2.8 M
Removing for dependencies:
