Default Re: xrandr shift after 302.17 not working.

Your first statement appears to be contradicted by the fact that 'xrandr -s 1920x1200' works. I say 'appears' as maybe that's covered by your second sentence?

Yup, worked a treat, so thank you for that!
The delay in switching between modes seems a wee bit longer than before (approx. 1.5 secs. vs. 0.5 secs before), but that is hardly an issue.

I found that I could also use:
nvidia-settings --assign 0/CurrentMetaMode="DFP-0: 1920x1200_60 +0+0, DFP-1: 1920x1200_60 +1920+0"
(... thanks to an answer you provided in a previous thread of mine.)

Since you say that my usual way of doing it is 1.1, and your solution (and my alternative CurrentMetaMode) is 1.2, can I safely assume that your 1.2 is the more 'correct' and future-proof method to use?
Or, in short: Which would you use?
