Remote desktop vs. remote displayRemote desktop vs. remote displayPosted Feb 14, 2013 22:55 UTC (Thu) by madscientist (subscriber, #16861)In reply to: Remote desktop vs. remote display by daglwn Parent article: LCA: The ways of Wayland
It's super-easy. I run Emacs in daemon mode (start "emacs --daemon") but this isn't required; if you don't do that you need to start the Emacs server yourself in your ~/.emacs file, or run M-x start-server by hand.
Then if your system running Emacs is named "server", just run:
ssh -X server emacsclient -c
The -c tells Emacs to create a new graphical frame, and since you're using ssh it will forward the display securely back to your local desktop.

This is actually a nice and useful tip. Thanks and kudos!

Typo: the command is M-x server-start

Well, almost:
Waiting for Emacs...X11 connection rejected because of wrong authentication.
*ERROR*: Display localhost:30.0 can't be opened
Any ideas?

I'm not sure LWN comments are the best place for a support conversation :-), but can you run other remote X operations (for example, can you run "ssh -X server xterm" and have the xterm show up locally)?

Yep, xterm works fine remotely.

Ah, I found this, which looks useful:

Hm. The original problem definitely sounded exactly like yours. However following the links to the recommended solution, I don't see how tramp is related. Anyway this looks way more complex; I certainly have never needed to copy a file like ~/.emacs.d/server/server to my local host. Things Just Work, with no extra help. If xterm works then it's probably not an issues with Xauthority etc. It seems bizarre to me but I suppose it could be a hostname thing. If on the server you say "ping server" does it work and give you a real IP address (not 127.0.0.1)? If on your client you say "ping server" does that work and give back the same IP address?
Have you tried starting Emacs in --daemon mode rather than using start-server? What version of Emacs do you have?
We may need to move this to the Emacs help mailing list: https://lists.gnu.org/mailman/listinfo/help-gnu-emacs
