Custom desktop environments by session users
You can specify a desktop environment for session users by using the CTX_XDL_DESKTOP_ENVIRONMENT variable. Starting with the 2209 release, session users can customize their own desktop environments. To let session users use this feature, you must install desktop environments on the VDA in advance.
The following table shows a matrix of the Linux distributions and the desktop environments that support custom desktop environments by session users.
| Linux distribution | Supported desktop |
|---|---|
| Debian11.3 | MATE, GNOME, GNOME-Classic, KDE |
| RHEL 8.8, RHEL 8.6 | MATE, GNOME, GNOME-Classic |
| RHEL 7.9 | MATE, GNOME, GNOME-Classic, KDE |
| Rocky Linux 8.8, Rocky Linux 8.6 | MATE, GNOME, GNOME-Classic, KDE |

You can switch between desktop environments from both the Terminal and the system tray.
To switch to a target desktop environment from the Terminal, run the corresponding command within the session:

KDE tips
- Magnus might load at startup in KDE. As a workaround, you can remove the Magnus package by running
sudo apt remove magnus. -
To disable QT warnings that occur during KDE startup, edit
/usr/share/qt5/qtlogging.inias a root user by adding the following entries:qt.qpa.xcb.xcberror.error=false qt.qpa.xcb.warning=false qt.qpa.xcb.error=false <!--NeedCopy--> - Screen unlock might fail for KDE. As a workaround, we recommend you disable the auto-lock feature of your desktop.
