OK, I had some more time to look at this. As I said above, systemsettings
changes won't take. Having set the DVI at 1920x1080(auto) and to be on the
right of VGA-0, I click on Apply and the DVI on the right of VGA reverts to
'Clone of' and the size stays the same as the VGA (1280x1024).
Then I ran xrandr again as Florian suggested and this is what it shows:
$ xrandr --output DVI-0 --auto <--this gives 1920x1080
$ xrandr --output DVI-0 --right-of-VGA-0 --verbose
xrandr: screen cannot be larger than 1920x1920 (desired size 3200x1080)
As a result it does not place the DVI on the right of the VGA driven monitor.
Can you please explain this error to me - why does it complain?
