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-desktop-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
~~~
