So there is nothing but a blank screen? That's bad...
Right. Sometimes there's a cursor at the top left, if I remember correctly.
Did you use shim.efi from openSUSE 13.2 DVD or the updated one?
The updated one. This was from 13.2 installed in a different partition on the same computer. To be more precise, I used "shim.efi", "grub.efi" and "MokManager.efi" from 13.2. I took those to be a matched set. But I can experiment with just one of those at a time if that would be useful. When I first booted after the update, it looked to me as if the firmware was freezing. So I powered off, powered on, and hit F2 to get into BIOS settings. That's when I tried turning off secure-boot. When that worked, it suggested a "shim" problem. So I experimented booting the DVD iso (on USB) with secure-boot on and off. And then I put back the ".efi" files from 13.2 to get things working. During my tests, I found that CTRL-ALT-DEL does reboot when the system is sitting on that blank screen. I'm not sure how to test what is going on. I think you would need a debugging version of "shim.efi" and it would need to be signed by Microsoft to be able to test with secure-boot -- unless there's a way of chaining a debug version from a working shim.efi, and have the debug version signed with a MokManager key. (I do have my own key installed, though I am not currently using it on this machine). -- You are receiving this mail because: You are on the CC list for the bug.
