I recently update to ubuntu 12.10.
I'm using an Nvidia gts 250 graphic card.
Before updating I was using Nvidia driver 302.17
But as Xserver updated this drive is not compatible anymore.
Instead I installed nvidia-current, but when I start the computer I get a black screen. When I go into recovery console and check the Xorg.0.log I cleary see X crashed :

Actually, it looks like I had Hybrid Sli enabled in Bios.
I deactived it and it now works.
