What to do if the VirtualHere GUI client is not displayed on your DietPi graphical desktop (e.g. See the “Configuration” tab below and the official documentation link for further details. If a device must stay available at the server, it is best to let it be ignored by VirtualHere, making use of the IgnoredDevices option: It takes xxxx/yyyy as value with xxxx being the vendor ID and yyyy being the device ID, which can be obtained from the output of lsusb. Be hence very careful to not select the wrong USB device in clients, especially when DietPi userdata or swap files are located on a USB drive. VirtualHere will forcefully “detach” even actively used USB drives on the host system, once you start using them with the client. USB devices cannot be used on the host server and the client system at the same time.

If you have an enterprise subscription on RealVNC, you can have virtual VNC sessions spawning automatically on demand per-client connection and closing once the client disconnects. Check all logs via journalctl -u vncserver-x11-serviced. ![]() If you set SOFTWARE_VNCSERVER_SHARE_DESKTOP=1 in /boot/dietpi.txt or select desktop auto login via dietpi-autostart (index 2), RealVNC server will be started on boot in shared desktop mode, attaching to the first found local desktop session.Ĭheck the service status via systemctl status vncserver-x11-serviced. Restart it via systemctl restart vncserver. When you logout (instead of only closing the VNC Viewer window), the session will exit. Logs can be viewed via journalctl -t Xvnc:1 -t vncserver and in /root/.vnc/. The screen index can be changed via SOFTWARE_VNCSERVER_DISPLAY_INDEX in /boot/dietpi.txt.
