I found that when I connect to my computing cluster via vnc Alt-x is not recognized correctly asM-. I tried vncserver -compatiblekbdbut I get Unable to start Xvnc, exitingActually once my session was started and in the log I found:Fatal server error:Unrecognized option: -compatiblekbd`How can I pass this option to vncserver and get the correct mapping  of  Alt+x ?
vncserver -compatiblekbd fails with unrecognized option
emacs;vnc
