Here is my problem. My laptop has an NVidia Geforce 310 M graphic card. And since kernel 2.6 I had problems with the display. I had to use nomodeset option in the grub, if not my screen will be off when the xorg starts even though my computer is running.
Fortunately, this problem was fixed in early 3.0 kernels. It was fine until kernel 3.4.x in which the problem was back. So I've been using the old kernel(3.3.x) from my grub list, and reported a bug at bugzilla. But they never replied to my questions about the bug on bugzilla.
Now, the real problem is the update manager says there are software updates and it want to remove the old kernel and install some 3.4.x kernel which I'm not sure if they fixed the problem. If I don't get display, I lost my fedora I should re-install some other OS or OS with kernel 3.3.x
What should I do?
