If you have been able to get X2Go or xRDP to work on Linux Mint (with Cinnamon), please leave a comment on how you got that to work :-) X11vnc + SSH I have also been unsuccessful with xRDP, but I’ll keep experimenting with xRDP on Linux Mint. I’m still playing around with X2Go, but unfortunately X2Go does not play nice with Cinnamon (the primary Linux Mint desktop environment). #VNC THROUGH SSH TUNNEL X11VNC PC#Windows RDP will “lock” the host PC, and when I am back in front of the physical PC I can pick right back up where I have left off.

Invalid MIT-MAGIC-COOKIE-1 key 12:14:26 XOpenDisplay(“:0”) failed.Double-click the Connection Profile you created earlier, and remotely connect to your X11vnc host:Ĭonnection to Remote X11vnc Host The Rest of the Story Then I enter the command ‘x11vnc -safer -localhost -nopw -once -display :0’ I get the x11vnc -safer -localhost -nopw -once -display :0 When I try logging into putty as an ssh tunnel things get tricky. Putty can still login the linux box using ipaddress, 22. I enable UFW with port 22 open on the linux box.
