KDE (desktop environment)
|
||
=========================
|
||
|
||
.. warning::
|
||
|
||
This page is intended for advanced users.
|
||
|
||
Installation
|
||
------------
|
||
|
||
|
||
Prior to R3.2, KDE was the default desktop environment in Qubes. Beginning with R3.2, however, :doc:`XFCE is the new default desktop environment </developer/releases/3_2/release-notes>`. Nonetheless, it is still possible to install KDE by issuing this command in dom0:
|
||
|
||
.. code:: bash
|
||
|
||
$ sudo qubes-dom0-update kde-settings-qubes
|
||
|
||
|
||
You may notice some warnings and errors in the installation - it is safe to ignore these.
|
||
|
||
After the installation is complete log out. At the top of the log in screen is a small icon with *X* on it - if you click on it you will see choices between Xfce and Plasma. Select the Plasma(X11) option, and log in - you will see that Plasma (the KDE desktop environment) loads.
|
||
|
||
KDE is very customisable, and there is a range of widgets to use. If you want to use the Menu widget, then you must edit ``/etc/X11/xinit/xinitrc.d/55xfce-qubes.sh`` as follows:
|
||
|
||
.. code:: bash
|
||
|
||
#!/usr/bin/sh
|
||
|
||
# Use Qubes provided menu instead of default XFCE one
|
||
if [ "$XDG_SESSION_DESKTOP" = "KDE" ]; then
|
||
XDG_MENU_PREFIX="kf5-"
|
||
else
|
||
XDG_MENU_PREFIX="qubes-"
|
||
fi
|
||
export XDG_MENU_PREFIX
|
||
|
||
|
||
|
||
This allows you to edit the menu as you will. When editing the Menu *DO NOT use the option under “Edit->Restore to System Menu”*
|
||
|
||
Login manager
|
||
^^^^^^^^^^^^^
|
||
|
||
|
||
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:
|
||
|
||
.. code:: bash
|
||
|
||
[XDisplay]
|
||
ServerArguments=-nolisten tcp -background none
|
||
|
||
|
||
|
||
- disable the lightdm service:
|
||
|
||
.. code:: bash
|
||
|
||
$ sudo systemctl disable lightdm
|
||
|
||
|
||
|
||
- enable the sddm service:
|
||
|
||
.. code:: bash
|
||
|
||
$ 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:
|
||
|
||
.. code:: python
|
||
|
||
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:
|
||
|
||
.. code:: bash
|
||
|
||
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:
|
||
|
||
.. code:: bash
|
||
|
||
sudo dnf remove kdelibs plasma-workspace
|
||
|
||
