Comment # 12 on bug 1178360 from Stefan Hundhammer

It just came back after "zypper dup" today.

When I boot the old kernel 5.8.18 from the Grub2 prompt, it's working okay.
When I boot the new kernel 5.9.1, I get the same pixel garbage.

I tried recreating the initrd ("sudo mkinitrd"), but that did not change
anything.
