The proprietary driver installed via the nvidia driver installer is not compatible with the 8400 GS according to the Xorg log: With some searching I found this: https://askubuntu.com/questions/739577/ ... ce-8400-gs
The claim is that the 340.108 version won't work with the 8400 GS and I need an older version (ie, 340.96).
That would seem to agree with the message in the Xorg log:

I went direct to nVidia website, but that only offers the 340.108 driver - and it claims it supports my card.
Cheers for your help!
