Once nice feature x2go has is that x2go sessions are persistent across connections if you kill the session without purposely logout. So when you reconnect, your terminal windows, applications, browser windows, etc., will still be where you left them, even your foreground running jobs are not interrupted.
If you do not need a full desktop environment and know a little about Linux, you may use a simpler X-window client program like MobaXterm (https://mobaxterm.mobatek.net/, Home Edition is free) instead of x2go. It allows you to run the GUI tools fine and it uses a lot less resources on our Linux server. You may also use the ssh command (eg, 'ssh -X class2.ece.virginia.edu') in a terminal window on macOS X or Windows Subsystem for Linux (WSL) to access ECE Linux servers.
