To anyone who understands UEFI in linux:
Today I almost lost my openSuse Leap 15.5 system graphics, due to the
fact that a native Nvidia GE-Force 710 driver install and kernel rebuild
to use the low level Nvidia modules in the kernel failed upon boot up
due to incorrect signing and subsequent rejection from the low level
bios as the kernel was being loaded.
I carefully followed the Nvidia installer directions and even had it
create a UEFI key pair, but my attempt to use the mokutil to help insert
this key pair into the HP Z420 workstation bios failed badly. The Z420
workstation bios firmware is NOT that clear either on inserting new key
pairs, as one attempt giving the full path failed badly.
To recover, I had to finally overwrite all the partitions, from backup
(always backup first!) especially the /boot, /etc, /usr partitions to be
able to restore the kernel and drivers to such a state that the Z420
workstation bios would accept them.
Has anyone worked with making new or custom kernels such as the Nvidia
G06 family and successfully gotten the UEFI keys to work?
I appreciate any tips in this regard. Even though YAST2 can remove the
nouveau graphics drivers in the kernel and add in the Nvidia G06 kernel,
even that fails to pass the UEFI keys check. I am not sure why that is
failing either.
Thank you.
Randall
