@2e9f5e44 my main advice is: if the price is "cheap" you're going to pay for it in frustration. I have a no-name 1:3 switcher with a single push-button that regularly drives me *nuts* when I can't get the monitor to wake properly with Linux. I think the culprit is bad EDID somewhere in the software stack. The single push-button is also slow and I regret not getting something with a button per input set.

I bought a GREATHTEK device for my mother a while ago which I kinda like, but not a duplex device. 

 @4ebb1885 this is a valid criticism for problems for which they *aren't* useful, and I am similarly insulted when I point that out in a narrow domain and someone jumps down my throat about how useful they are (in that person's opinion) in totally unrelated domains.

I don't think *everyone* who finds them useful/interesting is a credulous fool taken in by dancing bearware, but I also do believe that such fools do exist in non-trivial numbers. 

 @f29919fc I have done it, but sufficiently rarely and long ago that I cannot recall what for.

I would personally make an effort to be nice to it (especially if I could just detect that I'm about to enter murky waters and issue a warning) but wouldn't bend over too far to support it unless I had someone's specific workflow in mind
