title: KDE (desktop environment)
|

Installation
|
|
------------
|
|
|
|
Prior to R3.2, KDE was the default desktop environment in Qubes. Beginning with
|
|
R3.2, however, [XFCE is the new default desktop environment](/doc/releases/3.2/release-notes/). Nonetheless, it is
|
|
still possible to install KDE by issuing this command in dom0:
|
|
|
|
```shell_session
|
|
$ sudo qubes-dom0-update kde-settings-qubes
|
|
```
|
|
|
|
You can also change your default login manager (lightdm) to the new KDE default: sddm
|
|
|
|
* first you need to edit the `/etc/sddm.conf` to make sure if the custom X parameter is set according to Qubes needs:
|
|
|
|
~~~
|
|
[XDisplay]
|
|
ServerArguments=-nolisten tcp -background none
|
|
~~~
|
|
|
|
* disable the lightdm service:
|
|
|
|
~~~
|
|
$ sudo systemctl disable lightdm
|
|
~~~
|
|
|
|
* enable the sddm service:
|
|
|
|
~~~
|
|
$ sudo systemctl enable sddm
|
|
~~~
|
|
|
|
* reboot
|
|
|
|
If you encounter performance issues with KDE, try switching back to LightDM.

Window Management
|
|
-----------------
|
|
|
|
You can set each window's position and size like this:
|
|
|
|
~~~
|
|
Right click title bar --> More actions --> Special window settings...
|
|
|
|
Window matching tab
|
|
Window class (application): Exact Match: <vm_name>
|
|
Window title: Substring Match: <partial or full program name>
|
|
|
|
Size & Position tab
|
|
[x] Position: Apply Initially: x,y
|
|
[x] Size: Apply Initially: x,y
|
|
~~~
|
|
|
|
You can also use `kstart` to control virtual desktop placement like this:
|
|
|
|
~~~
|
|
kstart --desktop 3 --windowclass <vm_name> -q --tray -a <vm_name> '<run_program_command>'
|
|
~~~
|
|
|
|
(Replace "3" with whichever virtual desktop you want the window to be
|
|
on.)
|
|
|
|
This can be useful for creating a simple shell script which will set up your
|
|
workspace the way you like.
|
|
|
|
Removal
|
|
------------
|
|
|
|
If you decide to remove KDE do **not** use `dnf remove @kde-desktop-qubes`. You will almost certainly break your system.
|
|
|
|
The safest way to remove (most of) KDE is:
|
|
|
|
~~~
|
|
sudo dnf remove kdelibs plasma-workspace
|
|
~~~
|
