As mentioned in my previous email, my latest attempts were made using my
own laptop as the "remote" machine - I am not in possession of my
friend's computer at the moment.  So, yes, logically I suppose the
problem must be with my own desktop computer.

I'll try installing the full TeamViewer on my laptop when I have the
time, and see whether I get better results using that as the local
machine.

I just ran the TeamViewer Quick Support module on the remote machine - I
have not (yet) installed the full version on that computer.  I have
version 11 on the local machine.

I'll certainly try this when I have a chance.

'sudo lshw -C display' gives:

  *-display

The relevant section of the output from 'lspci -v' says:

Do you think that I should experiment with the nvidiafb driver?  I don't
have any issues at all with my video display, except when trying to view
remote desktops.
