Windows HVM and two monitors (dual head - dual headache ;-) ). Help appreciated.

[daltong defourne]

Well, first, the good thing:
Dual head windows HVM booted without issue.

(Qubes proper is also working with the second monitor and extending the qubes desktop to it, all fine)

Now, the bad thing - apparently, enabling "extend desktop to this monitor" in windows does literally nothing (seamless GUI disabled)

The second monitor still shows qubes desktop wallpaper.

Going fullscreen does nothing (windows VM occupies first screen allright, second screen remains "qubes wallpaper")

So far I am working around the following manner:
I disable second monitor in windows, then make windows VM's window "snap" to minimum size by dragging it upwards, then extend it so it covers both monitors in "qubes view"

Then I manage my windows in Windows (pardon the pun) with winsplit revolution (The only window splitter thingie that worked okay in Qubes VM for me)

What I'd like is capability for non-seamless windows VM to go into "full full" screen and occupy both monitors while doing so (in order not to waste any "pixel estate" to window borders and panel and such)

I dont know much about this topic as I dont have a dual screen.

What I do know is that 'full full' screens are not really something you would want. A malicous software could grab that 'full full' screen and start asking for sensitive information.

I also had an issue with 'full full' screen and then using RDP (that's what I use windows for anyway) and then not being able to regain control into my dom0 window manager, because something crashed or got stuck I was actually forced to reboot my machine.
I ended up using windows non-seamless, as a 'qubes-normal full screen' on my very last xfce desktop. thats where my windows lives and I'm happy with that setup.

Your situation is different, but this is just my two cents on how it works best for me.

I know that and do bear that in mind. Having said that, my windows HVM has no internet connection and if my Photoshop/Coreldraw/Excel/Word asks me for sensitive information, I'll be wary :)

How did you configure this? I got it working under VMM on Debian by adding
a secondary video adapter to the VM config but haven't been able to figure
out where I'd do the same under Qubes.

One thing I noticed under Debian is that if I used the viewer built in to
VMM, it wouldn't show me both monitors. I had to use virt-viewer instead.
That gave me two independent windows; one for each monitor. Obviously I
don't recommend trying to work around Qubes by using a non-standard viewer
because that could easily cause security issues, but it might be a
datapoint why you're only seeing one monitor.
