# Qubes OS: What to Change after Setup

## Annoyances

### System Beep Sound

On some systems, you'll hear an annoying beep sound on some menus, especially the logoff/shutdown menu. This seems to be more of an Xfce issue than a Qubes OS issue. The easiest way to get rid of it is to ..:

* Open the Qubes OS Menu
* Click the settings gear icon
* Click **Other**
* Open **Xfce Terminal**
* Type `xset b off`
* Hit enter
* Close the **Xfce Terminal** window

## Updates

The most important thing after the installation is getting the latest updates for all the subsystems that run the separate qubes (Whonix, Debian, Fedora). Although this is the latest version of Qubes OS, the underlying operating systems for the qubes need to be up-to-date as well:

## Cosmetics

These settings depend on your preferences:

* Open the Qubes OS Menu
* Click the settings gear icon
* Click **System Settings**
* Open **Settings Manager**:

* Appearance:
  * Switch to the "Adwaita-dark" theme
  * Select "Set matching Xfwm4 theme if there is one"
  * Navigate back to the main menu by clicking the < All Settings button.
* Desktop:
  * Style: None
  * Color: Solid color (I prefer a dark, distraction-free desktop background)
  * Navigate back to the main menu by clicking the < All Settings button.
* Panel:
  * Tab "Appearance": Select **Dark mode**.
  * Navigate back to the main menu by clicking the < All Settings button.
* Display:
  * If the display resolution is too high for a small laptop screen, you can change it here

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.remoteyon.com/linux/qubes-os-4.3.0/qubes-os-what-to-change-after-setup.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
