There is the problem in the first place. That's the bit I can't get to, as 
per my OP.
I can't get THAT far. If I could then I wouldn't be having the issue
and be here trygin to get an answer.

It could be something in Debian OR the Qubes Drivers. Not the Printer 
drivers, as I can't even get to the point to select them.

I have the HVM started before I even start an application.

I give it 2 minutes before I even clicked an application to start.
I even attempted to run a command using the "Run command
in VM" option from the manager.
Neither way worked. Nothing showed up.
Is there anything you have disabled in Windows to get it all to work 
properly?

But that is one thing I think they need to fix in the Tools too, because 
I noticed that it creates it as 1 large monitor, not as multiple
displays. Which it should, to prevent issues. It may even resolve some
of the issues I have been reading about in the bug reporting things.

The problem didn't resolve by re-trying the build (which maybe would be

How are you starting "print settings"? Did you try system-config-printer 
command from the terminal?  And So it finds the printer on the network but 
crashes when it says searching for drivers?I'm not sure what you mean by 
print settings and sub windows.  Wouldn't print settings be after you install 
it?  Never even heard of that model maybe you have to manually download the 
driver from their website for fedora? not sure.  You could also try asking on 
fedora forums.

actually,  sometimes windows hvm errors and won't load when selecting an app 
from the startmenu. So usually I just start the win7 vm manually from the 
qubes-manager first before loading a program from it.

Just a right click on the VM manager on the VM and than I can change the

By disappeared from the sytsem, I assum you mean you can't see it's
icon, rather than it being not installed. 

Are you running xfce? This happens in fedora xfce sometimes and can be
a bit frustrating. Try resizing the icon and menu bar several times.

[qubes-users] nm-applet disappeared

[ad5108676]

Hi, for some reason my nm-applet has disappeared from my system. I tried 
searching around for the cause of this, and the only causes I could find for 
Qubes 3 were deletion of the System Tray widget or related to changes in the 
NetVM template. I'm currently running the default configuration (aside from a 
few random applications installed in the fedora-23 template) and my System Tray 
is present. I have tried restarting the nm-applet, which generates a passed 
through notification that I'm connected to the network but does not display the 
applet. I'm not sure how long ago it stopped displaying either, I only noticed 
it because I wanted to change my network configuration and couldn't see the 
applet. Is there anything else I should try?

I've experienced this too. If I just wait about 10 seconds, then try
to start sys-net again, it always works.

[qubes-users] Re: Does Qubes play well with Computer vision, and ML?

[Arqwer]

AFAIK you will need to gave 2 GPUs if you want to pass one to VM. On PC you 
can buy one more GPU, but on laptop that might be a problem. Some laptops 
have 2 GPUs: one discrete, and one inside a CPU. Still, on some laptops 
(MSI GT72 for example), there are 2 GPUs, but they can not run 
simultaneously, only one at a time, what makes GPU passthrough impossible.

Btw, I am studing ML and CV for two years, and still never faced a 
necessity of using GPU. (May be it's just me). If there would be a case, 
when I will need a GPU, I can walkaround this problem by buying Amazon's 
virtual server with gpu.

Re: [qubes-users] Does Qubes play well with Computer vision, and ML?

[john.david.r.smith]

i never tried, but you can pass your pci devices to an appvm (e.g. your 
gpu).

https://www.qubes-os.org/doc/assigning-devices/

frameworks will often allow you to use your cpu in case you have no gpu.
as long as your models are small enough you can train that on cpu. (but 
training a big nn (neuronal network, but i guess you know that) will 
take a long time and cnns (and other deep nns) are big).


so passing through your gpu would be the best course of action.
(maybe your university provides some pcs with standard dev software and 
ssh-access. you could try using those.)
