SSH – can’t get gnome-session working over SSH

gnomessh

To sign into my office computer from my home computer through ssh I go through these two steps: first I login to my office server: ssh -X myOfficeServerID@myofficeServer then I sign in to my computer using the local IP: ssh -X myOfficeComputerID@myOfficeComputerIP. I want to be able to view my desktop remotely and work with the GUI.

This is result of running gnome-session:

[myOfficeComputerID@myOfficeComputer]$gnome-session

^C

These commands keep on continuing non stop until I press ^C as you saw in the commands:

Initializing nautilus-gdu extension
Initializing nautilus-open-terminal extension
Initializing nautilus-dropbox 1.4.0
Shutting down dropbox extension
Shutting down nautilus-open-terminal extension
Shutting down nautilus-gdu extension

In the mean while things like firefox run from my office computer but the bottom panel won't stop loading things.

Both SSH sessions need to be started using the -X option.

However, if you want your entire session, you may want to think about using something like X2go because it compresses images and has some proxies which make this a lot less bandwidth hungry AND it can restore sessions ...

And running the entire gnome-session can have unpleasant side effects, when your remote gnome-session starts a remote metacity which replaces your local window manager.

Your additional imformation shows the "unpleasant side effects" I mentioned. You cannot simply run gnome-session when you already have a desktop environment running, because gnome-session will try to take over and your running desktop environment won't let it that easily. For a X program it makes exactly no difference whether run remotely via SSH or locally.

Depending on what you want to achieve you can start a xnest session and use that for your remote gnome-session.

xnest -geometry 1280x1024 :123 &
DISPLAY=:123 ssh -X firsthop
ssh -X secondhop
gnome-session

NOTE: In some distributions the binary is named Xnest with a capital x.
