Cannot startup after upgrading my Fedora 18

edit

I have fedupped to f18 from 17 and the 2 latest kernels blank screen + ctr+Alt+F2 does not give me a screen -when I decrypt the hard drive blind & wait for HD activity to cease & put in my login & pw it looks likes it's working from the HD activity, but no screen.

When I boot from kernel 3.6.11-1fc17.i686.PAE I get no problems & system works very nicely, so I am wondering what changed in the kernel and can it be fixed?

this is a Toshiba sattelite P20 with NVIDIA Geforce FXGo5600

I have read some post about NVIDIA drivers problem and some additional parameters to set in Grub, but it sounded complicated for every boot.

I hope it can be fixed in a future kernel, can it?

Meanwhile, has anyone any suggestions how I can get a screen with the newest kernel?

what changes did you make?

I have upgraded using FedUp and also got a blank screen. Nevertheless, I switched to a different tty using Ctr+Alt+F2, and I saw that Fedora 18 was booted, so I logged in and made some changes there. Maybe you can also get logged in as I did. HTH!!
