@ Sean, Holger,

Thanks for your help.

I'm going to buy a burner laptop and play with Qubes now.

I'm aware v.4.0 is new. Would you recommend a newbie starts with an earlier 
version (if so, which one please)?

no, that's wrong. Qubes supports multiple displays just fine, it's just based
on an 1-2 year old version of Fedora, so it supports whatever that supports.

so newer graphic cards might cause problems, or certain old ones too.

2017-09-28 Thread Coracle 
I'm getting the message here and elsewhere that Qubes OS doesn't yet support 
extended desktops or multiple monitors. 

I want to build a navigation system for my boat based on Qubes OS. Modern nav 
systems control the autopilot and display large amounts of information on 
multiple monitors. Qubes OS offers not only a high level of security but also 
seems to offer an opportunity to run incompatible applications simultaneously. 
Not sure if this will mean anything to anyone here but I would like to run 
TimeZero + Navionics vector charts on Windows in one Qube simultaneously with 
OpenCPN + UKHO raster charts on Linux in a second Qube). 

Does anyone know whether Qube OS is eventually going to support multiple 
monitors?

Hope it works for you, Qubes is definitely a nice system once you are settled 
down. Btw you might know this already, however Qubes 4 is about to be released 
soon, and RC1 is already out. Perhaps your issues will be fixed in the new 
release, there is a chance with Fedora 25, new hardware support, etc.

I did try installing Qubes while the second monitor was on but I did not 
install nvidia propietary drivers to Dom0. I will reinstall as soon as I can

I cannot provide you with a straight solution, but perhaps a workaround. Here 
are some thoughts.

In my experience it often fails when you try to install Qubes with nvidia, 
especially modern cards, but old cards have their quirks too. It's especially 
bad without nvidia proprietary drivers, which have to be installed in Dom0 
after the Qubes installation if you want them to work properly. To begin with, 
it's nice that you even managed to boot up Qubes with your nvidia cards. 

* Did you install nvidia in Dom0 before attempting to enable your second 
monitor btw?
* Alternatively, did you try install Qubes while the second monitor was on?

* Also SLI might indeed be a factor too, you might want to try disable it and 
see if it works. Assuming that you're new to Qubes, imho, it's well worth the 
trouble, Qubes is awesome.

* Do you have on-board graphics? Like for example Intel integrated graphics in 
your CPU? Intel graphics is known to run quite well in Linux/Qubes.

If you do have Intel integrated graphics (change to primary in bios, you don't 
need to remove the graphic cards) then this is the most likely approach that 
will work without much trouble. Also you hardly need anything more than Intel 
graphics, Qubes can't run games or similar yet anyway. You will have to switch 
screen cables or use a KVM to do so, if you choose to dual-boot with windows or 
another system. Assuming you still use your graphics card on your dual-boot 
systems.

Also I find it odd that you have to re-install Qubes. I usually have the 
opposite problem, my screen settings never ever stick with me between reboots 
or screen reconnections, I believe the fault is in XFCE4, I have to make an 
automated script to make settings stick.

Perhaps a similar solution would make it easier to test without having to 
re-isntall Qubes every time. If you find the file which saves the second 
monitor configuaration, at least you should be able to edit it without having 
to re-install every time you try something new.

Does tty terminal work? (Ctrl+Alt+F2, Ctrl+Alt+F1, etc.)?
Irregardless, too little information, it would be helpful if you provide more 
details, especially if someone more knowledgeable drops by. I'm just a regular 
user like you, after all.
