# Qt Wayland

## Display server
To utilize Wayland for Qt-based applications install the `qt5-wayland` and `qt6-wayland` packages. Optionally, also install `qt5ct` and `qt6ct` if you're on a non-KDE desktop environment.

Then set the `QT_QPA_PLATFORM` environment variable to:

* `wayland` for the wayland plugin
* `xcb` for the X11 plugin
* `qt6ct` for running Qt6-based applications on non-KDE desktop environments
* `qt5ct` for running Qt5-based applications on non-KDE desktop environments

<p class="callout info"><strong>TIP:</strong> It may prove useful to set multiple values separated by <code>;</code>. In case one is not available, the next one is used.</p>

~~~bash
QT_QPA_PLATFORM="wayland;qt5ct;xcb"
~~~

## Use KDE dialogs
If some applications (e.g. Telegram) don't use default KDE dialogs, set the following environment variable:

~~~bash
QT_QPA_PLATFORMTHEME="flatpak"
~~~
