[qubes-users] Re: DaVinci Resolve 14 - Possible to run in a Windows VM on Qubes OS?

[J. Eppler]

What is DaVinci Resolve 14? Are you talking about this application: 
https://www.blackmagicdesign.com/products/davinciresolve/

Do you have to use this professionally or as a hobbyist?

Your complain regarding YouTube videos. I do not have issues with video or 
audio in YouTube videos.

Can you check if your audio settings where correct. I sometimes have issues, 
after I plugin other devices (e. g. microphone), afterwards my audio mixer is 
messed up. Which is easy to fix by adjusting the audio settings.

[qubes-users] How to Setup Wireless

[Ray Joseph]

How do I enter my password?  In Debian9, I installed wpa_supplicant to include 
a key in network/interfaces.  Should this same method be used for sys-net?

Where would I find this type of information.  Searching the Qubes-OS doc, I 
only found one reference to wireless and that was how to unload and load the 
wirel drivers.

BTW, I had cloned sys-net vm to experiment.  But it would not start.  Andrew 
pointed to developer docs where it was stated that a vm that would use a device 
already in use will not start.
https://github.com/QubesOS/qubes-issues/issues?q=is%3Aopen+is%3Aissue+label%3A%22C%3A+doc%22
 
Just for the record, since I will probably forget that.

Thanks,
Ray

David,

Thank you for sharing your config for conky.  I am going to install v4 and then

[qubes-users] DaVinci Resolve 14 - Possible to run in a Windows VM on Qubes OS?

[lemondezurich]

I'd really like to use Qubes.  The last time I tried it was on an Ultrabook and 
the install and setup was straightforward and painless.  However, when I tried 
to view a YouTube video in a browser window, I noticed the video playback 
wasn't perfectly smooth and there was NO AUDIO.

I'd like to revisit Qubes OS and see if it's feasible to use as my primary OS 
again, but this time I'd like to know if DaVinci Resolve 14 (there are Windows, 
Mac, and Linux versions) can be installed either to run under Linux or under a 
Windows VM.  People have gotten Resolve 14 to install and run under CentOS, 
Debian, Ubuntu, and other distributions.

I'd need audio to work.

If I could get youtube working with no performance or audio issues and DaVinci 
Resolve working on Qubes, I would gladly move to it full time.

Yes, I thought so too:)  But the command is just to run a chainloader,
and adding the option at the end of the line had no effect.

I might try mounting the usb stick in another Linux, copying the file-
system to disk, editing the xen.cfg file (I think that was the name),
and then building a new iso from that.  All a bit of a palaver, but
it ought to work.

Thanks for taking time to help.

Mike.

You should be able to press e and edit the kernel parameters while the xen 
choice menu is up?

r3.2 has a few issues with shortcut removal; if you're bored, you can remove 
the entries manually from submenus in (iirc) .local, .gnome and shared. 
Otherwise, just ignore them, and go by what the qubes-manager (or qvm-ls) tells 
you is installed. :)

As to templates, it doesn't matter so long as you are working with AppVMs 
(Standalone is a different story, for obvious reasons). Just reboot the appvm 
after shutting down the template, and you're good to go.

1200mb for fedora-minimal is about as low as it goes, you can run 
qvm-trim-template every once in a while to shrink the image.

[qubes-users] Qubes 3.2 questions and issues.....

[Graham]

Hi
I've not tried 4.0 yet, but I have been running 3.2 for a few weeks on my main 
production laptop, a thinkpad t440p. And qubes has been working better than I 
expected, but its a big learning curve going from windows to qubes, with only 
basic linux skills.

I'm going to try 4.0 on a separate ssd, once I obtain one. But at the moment 
I'm still playing around with 3.2.

During installation I selected luks encryption, which works fine. But my ssd is 
encrypted using the bios, so perhaps not using luks would give me better 
battery life, and cpu performance?

I did have trouble shutting qubes down. And, I found the best practice was to 
shutdown all vms and system vms, first. That way I'm guaranteed a quick and 
easy shutdown, without any issues.

The power manager on the taskbar occasionally crashes when being used, and I 
have to go to 'system tools' and restart it. 

I upgraded debian-8 to debian-9, and deleted the dedian-8 template from qubes 
manager but 'template: debian-8' still remains in the dom0 app menu. I've tried 
various cli commands to remove it but nothing works.

I'm confused how to install unsigned packages, and what the best practice is.

Should I install the package inside a new and clean templatevm, then create an 
appvm from that template? Or create a standalonevm from a clean template and 
install package inside the appvm? 

Also, the qubes instructions says fedora minimal uses 300mb disk space, but 
mine is currently using 1500mb. Which seems like a lot.

I've probably got more questions and issues. But so far Qubes is a great!

[qubes-users] Nouveau driver does not work during installation of 4.0rc2

[Mike Keehan]

Hi,

Installing 4.0rc2 fails after approx 600-700 packages.  I found
that one of the cpus was getting "stuck after 22secs" - the reason
seems to be that the nouveau driver does not work with the version
of the nvidia chips on my laptop (even the git kernel does not work
with it yet).

The same problem occurs when trying to install Fedora 26.

So I need to add "modprobe.blacklist=nouveau" to the kernel command
line when booting the installer.  This allows Fedora to install.
But I can't figure out a way to do that in the Qubes installer.
Anyone have an idea?

I tried using the grub command line, but the commands available do
not match up with the grub manual online - I'm presuming this is a 
security measure.

Mike.

Have a look at the code whonix or that VPN project uses to provide 
upstream services to downstream VMs.


The mechanisms are somewhat different in 3.2 and 4.0.

Your thoughts appear to be overly complicated. I e.g. didn't understand 
the dom0 part:


dom0 doesn't store any DNS settings. Each VM forwards packets to the 
next upstream VM and the DNS decision is made at your netvm resolv.conf. 
Dynamic firewalls (iptables in 3.2, netfilter or so in 4.0) managed by 
the dom0 qvm-firewall in your proxsy & firewall VMs ensure only allowed 
traffic is going through. DNS uses dnat rules. Dom0 uses your firewall 
VM to pull updates.


So you can just configure your DNS cache server in your net VM or if you 
want to use a proxy VM you'll have to write a custom service that does 
the iptables changes desired by the Qubes firewall (the default ones 
will not work as they are designed to forward packets further upstream). 
The latter should only be done by really experienced users.
