Sure, they probably won't be able to select *any* resolution (the compositor may limit it to multiples of 24 dpi or something). And they can certainly make an ugly set-up for themselves. However, I want them to be able to make something more-or-less reasonable and I see no reason why the compositor shouldn't coordinate this and why this "scale factor" can't be used for that. My primary concern is that integer multiples of 96 DPI isn't going to be enough granularity. I don't know whether we can really accomplish a higher granularity in a reasonable way. > Which email was your detailed proposition? > Alexander already gave me a very good reason why my original idea won't work (too restrictive on the protocol) and I now agree with him. That said, I'd like to find some way to accomplish the above. Thanks, --Jason Ekstrand
