Re: [qubes-users] Mouse and Keyboard Stuck After USB Qube

2017-01-28 Thread jgmalheiross
I have no ideia how to modify xen.cfg, and wasn't able to find any 
documentation online. Could you explain how you did that? I tried editing it 
with a bootable debian usb that I had laying around, but it only appears as an 
empty file.

I had the same issue.

This helped me: https://github.com/QubesOS/qubes-issues/issues/2270

Basically, I modified the xen.cfg to remove the entry that hides the usb 
controller from dom0 - rd.qubes.hide_all_usb

Re: [qubes-users] Mouse and Keyboard Stuck After USB Qube

Thank you for the reply. 

Yes, both my mouse and my keyboard are usb. Sorry for not saying it before. 

I tried unplugging and plugging them in again, but i didn't work. I'm still 
stuck in the login screen. 

I was wondering if there is any way to manually change how the dom0 handle usb 
(to disable proxies) through any recovery mode. It seems like the only way out, 
since I can't interact with the machine.

It sounds like you have a USB keyboard and a USB mouse (at least
internally, if not externally). When you created a USB qube, you
removed your (probably sole) USB controller from dom0 and instead
delegated it to your USB qube. So, now your keyboard and mouse only
work inside that USB qube.

I haven't experienced this issue firsthand on Qubes, but from what I
understand:

If you unplug your USB mouse and plug it back in again, you should be
prompted to enable the mouse input proxy (unless you were already
prompted earlier and declined).

Keyboard input is more difficult, since plugging in a USB keyboard
doesn't automatically prompt you to enable the keyboard proxy (last I
heard, anyway). If you can temporarily attach a PS/2 keyboard, for
example, the solution is to either disable the USB qube (which you can
actually do with just the mouse), then to unhide the USB controller
from dom0 (which requires the keyboard), or, alternatively, to enable
the keyboard input proxy in dom0.

You should be aware that enabling the keyboard input proxy in dom0
(and, to a lesser extent, the mouse input proxy) can be very
dangerous, since it gives your USB qube great power -- potentially
control of the entire system.

Perhaps someone who has dealt with these issues on Qubes 3.2 will be
able to speak from experience.

[qubes-users] Mouse and Keyboard Stuck After USB Qube

2017-01-27 Thread jgmalheiross
I just created a USB Qube, following the instructions from 
https://www.qubes-os.org/doc/usb/.
Immediately after booting the new qube, my mouse and keyboard stopped working.

After that, I waited for around 15 min, and nothing changed. So I powerd off my 
pc by pressing the button in the CPU.

When I turned it on again, my mouse and keyboard kept stuck in the page to 
input the password. The keyboard worked during the GRUB fase. 

I'm pretty sure that I only need to give the USB's control back to dom0, but I 
have no ideia how to do that now that I can't even log in. 

Has any one experienced similar problems? Do you know how I could solve that?

PS: Sorry for the grammar errors. I'm using my phone right now
