Since the last software update my boot choices have been damaged. Now when I click on the default OpenSUSE 15.3 I get to a black screen that does not respond to any input. Not even ctl-alt-del. When I reboot and choose the recovery option it leads me a number of kernel options and one of them works. Is there a way to completetly remove the grub2 settings and start over again?
Some folk have been seeing similar problems with the latest kernel, depending on their graphic hardware. I would guess your problem is more likely to be that than it is to be a grub2 issue.
I read through the bug report. The solution looks pretty complicated to me. Can we expect a simple kernel update to install soon, or I should I grapple with the complex solution.
