Exclamation API mismatch: nvidia

please help!

on the next day after installing thunderbird my computer was unable to load linux (fedora 13)
while loading it reaches the blue screen with logo and halts.
it didnt respond to any button. then i went to a single user by Ctrl+Alt+F1

because im a total newbie and thinking that video driver is missing, i installed nvidia using yum!
but the problem remains.

now entering startx gives:
API mismatch: the nvidia kernel module has version 195.36.24, but this nvidia driver component has version 260.19.12. there is always this error: no display specified

/etc/X11/xorg.cof file has Driver "nvidia" in the Section "Device", but it is supposed to be "nv", because it was so previously. manually editing this doesnt help.

1). is it possible to "unyum" what i did and get back the driver i used to have?
2). how can i get the display working?
3). were there any known to you cases when thunderbird could mess up display drivers? or is it just my "luck"?

i really need to sort this out asap guys. otherwise, have to reinstall linux at all!

It's saying that you have nvidia driver 195, but it's looking for driver 260 (which is current). nv is the OLD open source (non accelerated) nvidia driver. It has mostly been replaced with neoveou (I probably spelled that wrong) but as you're running the older 13, yes, you'd probably have nv still.

In order to get nv to work, you'd have to remove the module blacklisting of it and set your xorg.conf to use it again. Just changing it to nv will not fix as the nvidia package blacklists this driver if I remember correctly.

It would be best if you could get the correct nvidia proprietary driver installed as it has 2d/3d acceleration. I'm not certain why it's seeing 2 different driver version, I'm thinking it partially upgraded the nvidia package but didn't upgrade everything.

What repository did you get this from since you installed via yum? rpmfusion I'm guessing, but just want to make sure.

i guess you are right. there was rpmfusion when i searched using yum search nvidia before installation.

i have the original driver on a disk. if its possible how can i install it? i am asking for basic commands.

so you are saying to modify the file etc/modprobe.d/blacklist.conf. am i right?
