Hi,
just a few hours ago there was this kernel upgrade. Since restart, I’m getting at error message during boot, something like “kernel x.509 not working”. The computer continues to boot, but in only 640x480 resolution. When I checked my driver, it says Nouveau, so I installed the nVidia driver one more time. After installing, it says it works, but still uses Nouveau, and at booting, there is always this error message.
How did you install the nVidia driver?
Also you can ignore the error message, it’s not important (to the end user)
YasT one click from here: https://en.opensuse.org/SDB:NVIDIA_drivers
Zypper also says everything is alright, but the driver is still Nouveau.

It just didn’t happen before, and now the whole thing doesn’t work. :S
See here for both Problems, wrong cert and Nvidia:

And how did you reinstall it?
By just clicking on that 1-click install again?
That won’t do anything if it is already installed.
You have to remove the driver first.
Or better, just reinstall the kernel module package (nvidia-gfxG03-kmp-desktop) by right-clicking on it in YaST and selecting “Update Unconditionally”. Or run:
sudo zypper in -f nvidia-gfxG03-kmp-desktop
(this only applies if you installed the G03 driver, i.e. “for GeForce 8 and later”, otherwise you have to adapt that accoridingly to G02 or G04)
Zypper also says everything is alright, but the driver is still Nouveau.
The packages are ok, but the kernel module compiled for the previous kernel doesn’t work with the newer kernel.
You have to rebuild it, and the easiest way to do that is to reinstall the package.

Yes, but that’s totally unrelated to that message.
Btw, you can select the older kernel in “Advanced Options” in the boot menu, then the nvidia driver should work again.
There will be another kernel update soon which should fix this incompatibility, so you could also just uninstall the kernel-desktop-3.16.7-13.2 and wait for the followup update, instead of reinstalling the nvidia driver.
FYI, the incompatible kernel update has been removed from the update repo now.
So I’d rather recommend to just uninstall that updated kernel.
Run:
sudo zypper rm kernel-desktop-3.16.7-13.2
(or uninstall it in YaST via the “Versions” tab)
and reboot, the nvidia driver should work again.
When you get another kernel update, don’t hesitate to install it, the issue should be fixed then.
I reinstalled the nVidia driver with the new kernel, now it works. Thanks!
Ok, good.
Just remember that you likely will have to do that again after the next kernel update that will be released in a few days.
That one should fix the incompatibility of the current one, and will therefore be incompatible with the current kernel 3.16.7-13.2 (but compatible to the older ones again)… 
As mentioned already, reinstalling nvidia-gfxG03-kmp-desktop should be enough.
