I recently (2 months ago) installed a new GFX card as I got a 2K screen, and
installed the Nvidia drivers (compiled from source) as I would like to use the
card for lightweight GPU work.

I can't use the repo Nvidia drivers as won't install without the 32bit
software, and I've tabooed the base 32bit software ... it's unnecessary clutter
and doubles the volume of update traffic.

Initially I was getting checkerboard corruption on the GDM unlock login screen
following hibernate (but not sleep) but now it has extended to the desktop
background.

The change I made yesterday was to set the desktop background to a solid colour
instead of an image.

Gnome3 without wayland (I had troubles at the start with wayland)
