|

Qubes VM Manager should now look like the image below.
|
|
|
|
|
|
|
|
**Note:** Changing the `Window Decorations` from `Plastik for Qubes` will remove the border color and the VM name. The problem with `Plastik for Qubes` is, that it does not overwrite the background and text color for Minimize, Maximize and Close buttons. The three button are therefore hard to read.

The following text describes how to change the default light theme to a dark theme. This is just an example, feel free to adjust the appearance to your taste.

The image below shows the default light theme after installation.

This is the result after applying the steps described here.

1. Change Appearance
|
|
|
|
1. Open the `Appearance` dialog
|

|
|
|
|
|
|
|

|
|
|
|
**Note:** The black appearance theme `Xfce-dusk` makes the VM names in the `Qubes OS Manager` unreadable.
|
|
|
|

|
|
|
|
1. Open the `Window Manager` dialog
|

Dark App VM, Template VM, Standalone VM, HVM (Linux Gnome)
|
|
==========================================================
|
|
|
|
Almost all Qubes VMs use default applications based on the GTK toolkit. Therefore the description below is focused on tools from the Gnome Desktop Environment.
|
|
|
|
Using "Gnome-Tweak-Tool"
|
|
------------------------
|
|
|
|
The advantage of creating a dark themed Template VM is, that each AppVM which is derived from the Template VM will be dark themed by default.
|
|
|
|
**Note:** Gnome-Tweak-Tool crashes under Archlinux. A workaround is to assign the AppVM to another TemplateVM (Debian, Fedora) which has Gnome-Tweak-Tool installed. Start the AppVM and configure the settings. Shutdown the machine and switch the template VM back to Archlinux.
|
|
|
|
1. Start VM
|
|
|
|
**Note:** Remember that if you want to make the change persistent, the change needs to be made in the TemplateVM, not the AppVM.
|
|
|
|
2. Install `Gnome-Tweak-Tool`
|
|
|
|
- Fedora
|
|
|
|
sudo dnf install gnome-tweak-tool
|
|
|
|
- Debian
|
|
|
|
sudo apt-get install gnome-tweak-tool
|
|
|
|
3. *(Only AppVM)* Stop template and start AppVM
|
|
|
|
4. Add `Gnome-Tweak-Tool` to the Application Menu
|
|
|
|
1. `Right-click` on VM entry in `Qubes VM Manager` select `Add/remove app shortcuts`
|
|
|
|
2. Select `Tweak Tool` and press the `>` button to add it
|
|
|
|
|
|
|
|
5. Enable `Global Dark Theme`
|
|
|
|
1. *Debian only*
|
|
|
|
cd ~/.config/
|
|
mkdir gtk-3.0
|
|
cd gtk-3.0/
|
|
touch settings.ini
|
|
|
|
2. Start `Tweak Tool` from the VM application menu and set the `Global Dark Theme` switch to `on`
|
|
|
|
|
|
|
|
6. *(Optional)* Modify Firefox
|
|
|
|
**Note:** Firefox uses GTK style settings by default. This can create side effects such as unusable forms or search fields. One way to avoid this is to add the following line to `/rw/config/rc.local`:
|
|
|
|
sed -i.bak "s/Exec=firefox %u/Exec=bash -c 'GTK_THEME=Adwaita:light firefox %u'/g" /usr/share/applications/firefox.desktop
|
|
|
|
7. Restart VM or all application
|
|
|
|
Manually
|
|
--------
|
|
|
|
Manually works for Debian, Fedora and Archlinux.
|
|
|
|
1. Start VM
|
|
|
|
**Note:** Remember that if you want to make the change persistent, the change needs to be made in the TemplateVM, not the AppVM.
|
|
|
|
2. Enable `Global Dark Theme`
|
|
|
|
cd ~/.config/
|
|
mkdir gtk-3.0
|
|
cd gtk-3.0/
|
|
touch settings.ini
|
|
|
|
add the following lines to `settings.ini`
|
|
|
|
[Settings]
|
|
gtk-application-prefer-dark-theme=1
|
|
|
|
3. follow step 6 and 7 in: Using `Gnome-Tweak-Tool`
|
