Tested only on Ubuntu 22.04, likely work on RHEL based distributions too.
Assumes you already have DCV Viewer and YAD installed.
If you are running Wayland, the GUI will always launch in the Top Left of the screen.
You can disable Wayland by uncommenting the line
WaylandEnable=false in /etc/gdm3/custom.conf
Ubuntu: apt-get install yad
RHEL: dnf install yad
