sudo systemctl daemon-reload
sudo systemctl enable [email protected]
sudo systemctl start [email protected]Note: This [email protected] currently fails when being started. Nevertheless, the /usr/bin/Xtigervnc process will be started and works just fine. Need to be fixed in the future.
Reboot the system
Verify if the /usr/bin/Xtigervnc process runs:
