A qube has read-only access to the filesystem of the Template on which it's based, so a qube cannot modify a Template in any way.

Alternatively, you can use a suite of GUI tools, most of which are always available through desktop widgets.
|
||||
The two most important widgets are Domains Widget and Devices Widget.
|
||||
**Domains Widget** allows you to manage running qubes, turn them on or off and monitor memory usage.
|
||||
**Devices Widget** allows you to attach and detach devices - such as USB drives or cameras - to qubes.
|
||||
The **Disk Space Widget** will notify you if you're ever running out of disk space, and the **Updates Widget** will inform you that template updates are available.
|
||||
|
||||
|
||||
|
||||
|
||||
For an overview of the entire system, you can use **Qube Manager** (available from Start → System Tools → Qube Manager), which displays state of all qubes in your QubesOS.
|
||||
Alternatively, you can use a rather intuitive GUI tool called **Qubes VM Manager**.
|
||||
It supports most of the functionality that command line tools provide.
|
||||
The Qubes VM Manager starts and opens automatically when Qubes starts up, but you can also start it by going to Start → System Tools → Qubes Manager.
|
||||
Once the Qubes VM Manager is running, you can open the window at any time by clicking on the Qubes tray icon, which typically resides in the bottom-right corner of the screen.

Introduction
|

------------
|
||||
|
||||
In Qubes OS, you run all your programs in lightweight [virtual machines (VMs)] called [qubes].
|
||||
Not every app runs in its own qube.
|
||||
(That would be a big waste of resources!)
|
||||
Instead, each qube represents a [security domain] (e.g., "work," "personal," and "banking").
|
||||
By default, all qubes are based on a single, common [template], although you can create more templates if you wish.
|
||||
When you create a new qube, you don't copy the whole root filesystem needed for this qube to work (which would include copying all the programs).
|
||||
Instead, each qube *shares* the root filesystem with its respective TemplateVM.
|
||||
A qube has read-only access to the filesystem of the Template on which it's based, so a qube cannot modify a TemplateVM in any way.
|
||||
This is important, as it means that if a qube is ever compromised, the TemplateVM on which it's based (and any other qubes based on that TemplateVM) will still be safe.
|
||||
So creating a large number of domains is cheap: each one needs only as much disk space as is necessary to store its private files (e.g., the "home" folder).

If you've installed Qubes OS using the default options, a few qubes have already been created for you:

- personal
|

- untrusted
|
||||
- work
|
||||
- personal
|
||||
- untrusted
|
||||
|
||||
Each qube, apart from having a distinct name, is also assigned a **label**, which is one of several pre-defined colors.
|
||||
The trusted window manager uses these colors in order to draw window decorations (color frames) around the windows of applications running in each qube.
|
||||
It's totally up to you how you'd like to interpret these colors.
|
||||
You might like to use them to quickly and easily identify the trust level of a given window at a glance.
|
||||
Personally, I find it natural to associate red with that which is untrusted and dangerous (the “red light” -- stop! danger!), green with that which is safe and trusted, and yellow and orange with things in the middle.
|
||||
I've also extended this scheme to include blue and black, which I interpret as indicating progressively more trusted domains than green, with black being ultimately trusted.
|
||||
Alternatively you might use the colors to show that qubes belong to the same domain - for example, you might use 3 or 4 qubes for work activities, and give them all the same distinct color label. It's entirely up to you.

Each qube, apart from having a distinct name, is also assigned a **label**, which is one of several predefined colors.
|
||||
The trusted window manager uses these colors in order to draw colored borders around the windows of applications running in each qube.
|
||||
This is designed to allow you to quickly and easily identify the trust level of a given window at a glance.
|
||||
Most Qubes OS users associate red with what's untrusted and dangerous (like a red light -- stop! danger!), green with what's safe and trusted, and yellow and orange with things in the middle.
|
||||
This color scheme also extends to include blue and black, which are usually interpreted as indicating progressively more trusted domains than green, with black being ultimately trusted.
|
||||
However, it's totally up to you how you'd like to interpret these colors.
|
||||
Qubes OS doesn't assume anything about these colors.
|
||||
When you make a new qube, the system doesn't do anything special to it depending on whether it's black or red, for example.
|
||||
The only difference is which color you see and the meaning you assign to that color in your mind.
|
||||
For example, you could use the colors to show that qubes belong to the same domain.
|
||||
You might use three or four qubes for work activities and give them all the same distinct color label, for instance.
|
||||
It's entirely up to you.
|
||||
|
||||
|
||||
|
||||
|
||||
In addition to qubes and TemplateVMs, there's one special domain called "dom0," which is where the Desktop Manager runs.
|
||||
This is where you log in to the system.
|
||||
Dom0 is more trusted than any other domain (including TemplateVMs and black-labeled qubes).
|
||||
If dom0 were ever compromised, it would be Game Over<sup>TM</sup>.
|
||||
(The entire system would effectively be compromised.)
|

Due to its overarching importance, dom0 has no network connectivity and is used only for running the Window and Desktop Managers.

How many qubes do I need?
|

-------------------------
|
||||
|
||||
That's a great question, but there's no one-size-fits-all answer.
|
||||
It depends on the structure of your digital life, and this is at least a little different for everyone.
|
||||
If you plan on using your system for work, then it also depends on what kind of job you do.
|
||||
|
||||
It's a good idea to start out with the three qubes created automatically by the installer: work, personal, and untrusted.
|
||||
Then, if and when you start to feel that some activity just doesn't fit into any of your existing qubes, or you want to partition some part of your life, you can easily create a new qube for it.
|
||||
You'll also be able to easily copy any files you need to the newly created qube, as explained [here](/doc/copying-files/).

Running an application Full Screen
|
||||
----------------------------------
|
||||
If you encounter any problems, please visit the [Help, Support, and Mailing Lists] page.
|
||||
|
||||
By default, Qubes doesn't allow any application window to occupy the entire screen such that its window name (which includes the name of the qube to which it belongs) and colored window border are no longer visible.
|
||||
This is a security precaution designed to prevent a situation in which an application which has been allowed to enter full screen mode begins to emulate the entire Qubes system.
|
||||
The user should always be able to identify which qube is displaying any given window.
|
||||
Otherwise, a compromised qube which is able to occupy the entire screen could trick the user into thinking that she is interacting with a variety of different qubes (including dom0), when in fact she is interacting with only a single, compromised qube pretending to be the whole system.
|
||||
|
||||
**Note:** A similar attack is possible even *without* fullscreen mode.
|
||||
Since a compromised qube can draw pixels within its own windows however it likes, it could draw a fake password prompt, for example, which appears to have a different colored border so that it looks like it belongs to a different qube.
|
||||
This is why you should always drag such prompts away from other windows (or use some other means of manipulating the windows) to ensure that they belong to the qube to which they appear to belong.

|
||||
To allow a qube to enter full screen mode, one should edit the `/etc/qubes/guid.conf` file in dom0.
|
||||
|
||||
To allow all qubes to enter full screen mode, set `allow_fullscreen` flag to `true` in the `global` section:
|
||||
|
||||
global: {
|
||||
# default values
|
||||
allow_fullscreen = false;
|
||||
#allow_utf8_titles = false;
|
||||
#secure_copy_sequence = "Ctrl-Shift-c";
|
||||
#secure_paste_sequence = "Ctrl-Shift-v";
|
||||
#windows_count_limit = 500;
|
||||
};
|
||||
|
||||
To allow only select qubes to enter full screen mode, create a per-VM section, and set `allow_fullscreen` flag there to `true`:
|
||||
|
||||
VM: {
|
||||
work: {
|
||||
allow_fullscreen = true;
|
||||
};
|
||||
|
||||
};
|
||||
|
||||
In order for the changes to take effect, restart the qube(s).
|
||||
