Hi Ralf, sorry about the difficulty. I have no similar difficulty
understanding your posts. I'd be happy to try to re-write any part
which wasn't clear - if you think it would help. PM if you like. :)

Yes, I think that could be it. I noticed a package in Synaptic called
glx-alternative-nvidia, which is indicated as "Broken" if I try to
mark it for installation. It "allows the selection of NVIDIA as GLX
provider".

Understood, thank you, but I must have good 3D acceleration for
screen-savers ;) and games of course, but really - some of the
X screen savers are simply stunning [1]. Also Qt5 is out! [2]

I don't have access to my email client on the new install, but
from memory a low-latency 3.8

Yes. "Failed to load the NVIDIA kernel module. Please check your
system's kernel log for additional error messages."

And "Failed to load module "nvidia" (module-specific error, 0)"
and more. I'll see what happens with Xubuntu and work on from there
if I have more success with a Generic kernel.

Thanks.
