• You can press Sift+Win+M to get a full desktop when the logon applet is displayed. Disable this function by setting cfg_exittodesktop to 0 in ptermconman.py
• A logfile of xfreerdp (ptermlog.txt) is in the ~/pterm directory. It's useful to debug failed connections.
• You can edit the ptermconman.yaml file to change default settings. Reboot after editing
