I understand that I should be able to use X11 to show graphs from a remote R when I use a local emacs to connect to the remote machine with tramp.
I have tried a few different things but can not get it to work. I know that the server will work with X11 as if I ssh in using a normal terminal it works.
.emacs file has:
;; emacs x11 tramp (add-to-list 'tramp-remote-process-environment (format "DISPLAY=%s" (getenv "DISPLAY"))) (with-eval-after-load 'tramp (add-to-list 'tramp-methods '("sshx11" (tramp-login-program "ssh") (tramp-login-args (("-l" "%u") ("-p" "%p") ("%c") ("-e" "none") ("-Y") ("%h"))) ; tried -Y and -X :( (tramp-async-args (("-q"))) (tramp-remote-shell "/bin/sh") (tramp-remote-shell-login ("-l")) (tramp-remote-shell-args ("-c")) (tramp-gw-args (("-o" "GlobalKnownHostsFile=/dev/null") ("-o" "UserKnownHostsFile=/dev/null") ("-o" "StrictHostKeyChecking=no") ("-o" "ForwardX11=yes"))) (tramp-default-port 22))) (tramp-set-completion-function "sshx11" tramp-completion-function-alist-ssh))
On my local machine I also have two files,
sshd_config in my
.ssh folder. The latter simply contains
X11Forwarding yes whereas the former has
ForwardX11Trusted yes (with appropriate subs)
I connect to my server with
C-x C-f sshx11:user@host:/
I then do
M-x shell and select the "remote shell path" (to bin bash) and the starting directory.
Now when in the shell if I try
echo $DISPLAY I get
But if I try to load an xprogram such as
xterm to test I get:
xterm Xt error: Can't open display: /private/tmp/com.apple.launchd.zmPeFoMlxA/org.macosforge.xquartz:0
