After a kernel update (automatic, with online update) in my startup options openSUSE 10.2 was missing, I had two more options: Kernel-2.6.18.8-0.1-default and Kernel-2.6.18.8-0.1-default. Aslo I cannot run the gui (after logging in, in text mode when I type "startx" says : Module nvidia not found, Fatal server error :no screens found)
Is there a possibility to recover my system? I think it is a kernel problem
Please post a solutiom, I hope I haven't f@$%ed my system...

If you upgrade the kernel, you probably have to reinstall the nVidia drivers - they are linked to the current kernel sources

It would appear there is no issue other than you need to reinstall the nvidia driver module due to the kernel change. This is not in any way unusual with some types of kernel upgrades. Grub's menu.lst got written over with something unusually cryptic for Suse and that is probably a bug, but it still boots your system properly so just edit to something different if you wish in regards to a title.

If you just wish to get back to a GUI now:

# sax2 -r -m 0=vesa

This is a known bug. Take a look here

Anyway does anyone know how to install the previous kernel version?
I suppose this is going to solve my problem

Just run yast from the command line. The CD version of the kernel is always available to be used on the system and can be installed at any time. Since your computer is booting properly right now save for a GUI all you really need to do is fix the nvidia module issue and you should be fine.

From the command line:

$ su
<password>
# yast2

Then just navigate to the software module and reinstall the original kernel.

yeah i had a problem with this kernel update too, everything seems to work ok but 'opensuse 10.2' is now missing from grub and it just shows the kernel version.

It still shows the nvidia splash screen etc but you think thats what i ned to do reinstall my nvidia drivers?

No, if you can boot to your desktop w/nvidia splash then you are good.
Simply "clean up" grub's menu.lst if you desire.

Your update went a lot better than mine... The kernel update on mine trashed my partitions. I'm now reinstalling and reloading from backups (turned them into swap, very bizarre). Argh.

First time I've ever had a SuSE patch let me down, but it's the 3rd time in 3 tries that a Linux kernel patch has trashed the system I put it on (the other 2 systems were RHEL and CentOS, neither of which I'm very fond of, so it was a good opportunity to abandon them anyways). This does beg the question though, are Linux patches getting flakier all the time now, or do I have really bad luck? :-)
