[qubes-users] New user guide: How to organize your qubes

[Andrew David Wong]

Dear Qubes Community,

We have just published a new article:

"New user guide: How to organize your qubes"
https://www.qubes-os.org/news/2022/10/28/how-to-organize-your-qubes/

As a courtesy to plain-text email users, the plain-text source is reproduced 
below.

8<

_The following is a new [how-to guide](/doc/#how-to-guides) for users who are
starting out with Qubes OS. You can also find it in our [documentation](/doc/)
under [How to organize your qubes](/doc/how-to-organize-your-qubes/)._


When people first learn about Qubes OS, their initial reaction is often, "Wow,
this looks really cool! But... what can I actually *do* with it?" It's not
always obvious which qubes you should create, what you should do in each one,
and whether your organizational ideas makes sense from a security or usage
perspective.

Each qube is essentially a secure compartment, and you can create as many of
them as you like and connect them to each other in various ways. They're sort
of like Lego blocks in the sense that you can build whatever you want. But if
you're not sure what to build, then this open-ended freedom can be daunting.
It's a bit like staring at a blank document when you first sit down to write
something. The possibilities are endless, and you may not know where to begin!

The truth is that no one else can tell you *exactly* how you should organize
your qubes, as there is no single correct answer to that question. It depends
on your needs, desires, and preferences. Every user's optimal setup will be
different. However, what we *can* do is provide you with some illustrative
examples based on questionnaires and interviews with Qubes users and
developers, as well as our own personal experience and insight from using Qubes
over the years. You may be able to adapt some of these examples to fit your own
unique situation. More importantly, walking you through the rationale behind
various decisions will teach you how to apply the same thought process to your
own organizational decisions. Let's begin!


## Alice, the software developer

Alice is a freelance dev who works on several projects for different clients
simultaneously. The projects have varying requirements and often different
build environments. She has a separate set of qubes for each project. She keeps
them organized by coming up with a naming scheme, such as:

```
clientA-code
clientA-build
clientA-test
clientA-prod
projectB-code
projectB-build-test
projectB-prod
...
```

This helps her keep groups of qubes organized in a set. Some of her qubes are
based on [Debian templates](/doc/templates/debian/), while others are based on
[Fedora templates](/doc/templates/fedora/). The reason for this is that some
software packages are more readily available in one distribution as opposed to
the other. Alice's setup looks like this:

[![Alice's system: diagram 
1](/attachment/doc/howto_use_qubes_alice_1.png)](/attachment/doc/howto_use_qubes_alice_1.png)

- **Several qubes for writing code.** Here's where she runs her IDE, commits
  code, and signs her commits. These qubes are based on different templates
  depending on which tools and which development environment she needs. In
  general, Alice likes to have a separate qube of this type for each client or
  each project. This allows her to keep everything organized and avoid
  accidentally mixing up any access credentials or client code, which could be
  disastrous. This also allows her to truthfully tell her clients that their
  code is always securely isolated from all her other clients. She likes to use
  the [Qubes firewall](/doc/firewall/) to restrict these qubes' network access
  to only the code repositories she needs in that qube in order to avoid
  accidentally interacting with anything else on her local network or on the
  internet. Alice also has some qubes of this type for personal programming
  projects that she works on just for fun when she has "free time" (whatever
  that is).

- **Several qubes for building and testing.** Again, Alice usually likes to
  have one of these for each client or project in order to keep things
  organized. However, this can become rather cumbersome and memory-intensive
  when many such qubes are running at the same time, so Alice will sometimes
  use the same qube for building and testing, or for multiple projects that
  require the same environment, when she decides that the marginal benefits of
  extra compartmentalization aren't worth the trouble. Here's where she pulls
  any dependencies she needs, compiles her code, runs her build toolchain, and
  tests her deliverables. In some cases, she finds it useful to use
  [standalones](/doc/standalones-and-hvms/) for these so that it's easier to
  quickly [install different pieces of software](/doc/how-to-install-software/)
  without having to juggle rebooting both the template and an app qube. She
  also sometimes finds it necessary (or just convenient) to

I had a similar problem with the desktop wallpaper under Qubes 4.0.  It went 
away after doing something similar.

[qubes-users] Re: Task bar disappeared?

[Scat]

Update:
- I typed: xfce4-panel into the Dom0 terminal
- I received errors in the Dom0 terminal and as mentioned the Task bar 
appeared

It didn't survive a reboot of my computer. I typed:  xfce4-panel into Dom0 
it appeared...

How do I fix this so it survives a reboot?

[qubes-users] Task bar disappeared?

[Scat]

I just had a strange experience, here is what happened:

- My computer accidentally shut down as the computer became unplugged
- I am not sure if I accidentally hid the task bar?

Regardless my task bar disappeared...not sure I am using the right term but 
I am refering to the bar, on my desktop, it was ontop of the screen. This 
task bar had icons for my wifi, battery, clock, etc...

I can only access my templates by left clicking on my desktop...

If my memory serves me right, I control this via the "panel" however when I 
go to:
Applications -> System Tools->Panel

I get an error "Failed to show the preference dialog - 
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name is not 
activatable"

I found this solution:
https://forum.qubes-os.org/t/failed-to-show-preferences-dialogue/10087

Which brought the panel back...strange. Never had this before...

This was the solution provided on the link above:

Actually, this is the solution
@Qubes_User171  should start 
terminal in dom0, execute xfce4-panel. Panel will show up. Then it is 
needed forcibly to close the terminal regardless of the warning. The panel 
will disappear and reappear in a flash second. It usually happens when 
using context menu while on panel which somehow triggers closing the panel 
without the warning. 


Newbie question but what command do I type in Dom0 to "execute"? Do I need 
to do something when they say "Then it is needed forcibly to close the 
terminal regardless of the warning."?

Thanks...
