    Default Repair after faulty kernel update

    After installing the software updates today via YaST, including an update to the kernel version 5.3.18-150300.59.43.1-x86_64 (from 5.3.18-59.40.1-x86_64) the system refuses to boot wit the new kernel.
    Rebooting with the old kernel works fine.

    1. Is something wrong with the new kernel?
    2. If the new kernel is faulty, what is the YaST procedure to ditch it 'permanently?

    Of course, the failure may have been due to a fault in one of the other packages (e.g. gdm) also in the update.

    "refuse to boot" is rather vague. And a faulty gdm will not stop the system from booting, it will only not show you a GUI login.

    Sorry, for the vagueness. I can only describe what I see on the screen. Let me know what log data I could perhaps fish out, and how to do it!

    The boot process starts with the selection of the kernel version, which is now by default the new one and the screen then goes black and nothing more happens.

    Ok, that is something. Did you try if hitting the Esc key shows something?

    Hitting the Esc key has no effect during the boot. However, booting with the 'rescue' version of the new kernel does start a log output which terminates after a few seconds with the black screen.

    Hi
    Can you add the boot option at grub nomodeset and try booting temporarily with that. What graphics card in this system?

    Graphics card is Radeon HD 6450 1 GB DDR3.

    How, where do I set the grub nomodeset boot option?

    Hi
    At the grub screen, press e to edit, find the line linux or linuxefi and after the quiet add nomodeset then press F10 to boot.

    The same thing just happened to me. After update of the kernel, It won't boot, the escape key shows nothing. The previous kernel boots. I tried "rescue" using the installation DVD, but I have no idea what to do with that.
