To all:
It's been a really bumpy ride activating the appropriate video drivers
for my Nvidia GEForce 710T vga card.
Here's what lsmod shows now
owner@localhost:~> lsmod | grep nv
nvidia_drm 69632 6
nvidia_modeset 1204224 16 nvidia_drm
nvidia_uvm 1130496 0
nvidia 35471360 845 nvidia_uvm,nvidia_modeset
drm_kms_helper 303104 1 nvidia_drm
drm 630784 10 drm_kms_helper,nvidia,nvidia_drm
so my system is now running with native Nvidia drivers (signed, btw)
What is missing is the fact that the OpenSuse Leap 15.4 is using signed
kernel modules, and my HP 420 Workstation is a UEFI system, expecting
signing keys before enabling kernel modules, and having to manually sign
modules eluded me.
Worse, Nvidia listed the WRONG driver to download the G06 series
although their website says G06 for the 710T card, but an error message
from the kernel during boot time, lecturing me that I could NOT install
the 515 series drivers, caused me to go back and drop back down to the
legacy 471.141 series. Fortunately I had installed the Nvidia repository
so I could make the change under openSuse's yast2 program or zypper.
btw: trying to do the native Nvidia install forces the UEFI user to
enter both a public and private key and I have NO idea where they are
stored, although running the mokutil --list-all is useful, but still
doesn't tell you where the keys are.
I had to reboot, but then enter the UEFI firmware, remove the G06 key
and install the G05 key. After all this, I was able to bring up Leap
15.4 without a hitch, so I am running nvidia modules directly now
All this is like a gob-smacker, to someone who's never done this before
(me) so I had to work my way through all of this carefully.
Thanks for all the replies, they are appreciated!
