Yes, well, from the logs it is evident that the monitor gets properly detected
in both cases (when in focus and when not), but the resolution chosen
(automatically) when not in focus is wrong, 800x600. This is probably some
artifact of the interaction with KVM. Not sure precisely where is the problem,
though.

Yes, that should be it. Try it out and see if it works. You should probably
try it both when in focus and when not. It just might happen that the system
refuses to give you 1680x1050 when not in focus, so in that case you should
manually switch the resolution every time you get focus (with the above
command).

No, AFAIK xrandr is interactive and does not store the settings anywhere. If
you want the settings to stick, you can either use xorg.conf, or create a
script (with the above command inside) and execute it whenever necessary ---
after login, or after getting focus, or whenever the resolution isn't
correct...

It appears you have two DVI outputs on your graphics card, but only one is
connected to a monitor. I guess that the outputs are equivalent and either can
be used, but if you want to test it, just plug in the cable in the other
connector. :-) Anyway, I believe this should not matter much.
Best, :-)
