I was able to do that ALMOST acceptably by doing the steps described here:
https://github.com/QubesOS/qubes-issues/issues/3480
But just as the person reporting there I am being thwarted by a nasty "ghost mouse/click" bug.
Has anyone ever found a workaround for this issue? Is there perhaps a better way to do a dual-head (maybe we could get both "screen-windows" originate from QGA.exe?)
P.S.: I initially posted about this in qubes-devel in hopes that maybe someone there would know a workaround for this. Posting here in hope that maybe someone also tried to do a dual-head in windows under Qubes and figured out workaround for issue currently plaguing me.
oh, I've never seen this Qubes-win7 ghost bug version before, maybe it's because I didn't find time yet to re-install my Win7 and just kept my old Win7 from Qubes 3.2. for the time being.
I do encounter another mouse bug though, which you "might" encounter too given you mention mouse button issues as well. It makes the left/right mouse buttons unresponsive, but that's just that, nothing else happens in this bug, no ghosting or odd behaviours, all it does is right/left buttons stop working. If you ever encounter it too, then try use the middle-click button, which should instantly bring your mouse's left/right buttons back again too (quick easy fix, but it can happen up to multiple times a day though).
Chances are the ghost bug is an entirely different bug though, but if you ever discover this one, try middle-mouse. If you're on mouse-pad, some have a middle button in-between there, despite it not being visible. Perhaps other keys can trick it back as well.
Unfortunately I know absolutely nothing about the ghost bug though, I've never seen it my self. I suspect it might be the Qubes mouse driver though, maybe it can be modified by changing Window's behavior a bit in regedit or something akin to that, i.e. maybe some feature needs to be disable/enabled/changed-value (it's a possible scenario imho, question is how to find such speculative information).
awokd's hack looks really interesting too.
I just noticed that my firefox in a normal fedora qube, when writing in the address field, caused the dropdown list of suggestions in the search/address field, to appear on the second screen, despite firefox being on the first screen.
Maybe this is a related bug? I have no ways to connect them though, but it could potentially be a related issue. So it seems Qubes can't completely follow the screen borders? and this might not be a uniquely Windows issue?
Thanks for suggestion!
That's what I am doing now, but the "stretch window across two screens" is working out bad for me, because resolutions differ between two my screens, and I end up wasting a chunk of space on main screen (and it looks ugly)
The "honest two windows for honest two screens" approach is much more promising, if only someone could find a way to get rid of them ghost clicks.

Fat fingers, sorry.
