Environment variable $DISPLAY removed when using remote ssh extension in linux about vscode HOT 11 CLOSED

some more add on Steps to Reproduce

1. install vscode and enable remote ssh
2. add new host with ssh -X username@host
3. connect.
4. Terminal -> New Terminal

from vscode.

Just to clarify, The $DISPLAY environment variable is supposed to live on the remote machine, right?

from vscode.

Yes, it is. local $DISPLAY may not need to be concerned.

I've tested with manually broken local $DISPLAY with "" + ssh -X connect to remote.
in this case, remote creates $DISPLAY but not works. (so it is totally different case with this issue)

from vscode.

And it works when you do ssh-remote + integrated terminal and manually set $DISPLAY ?

from vscode.

Hmm... actually, that "works" not properly works.

If I connect with other shell (for example bash terminal) and connect with ssh -X, local & remote creates display connection rule, between local and remote. that is what we called $DISPLAY in remote machine.

what we call "manually setting $DISPLAY" is borrowing those connection temporary.
When we lost other shell (for example bash terminal) which maintaining that connection,
$DISPLAY broke and not working any more.

from vscode.

for example )
ssh-remote + integrated terminal connected to remote get's
$DISPLAY variable of "" which is null

in this case, how we should set $DISPLAY ?
answer is we don't know.

to get answer, we need to prepare another ssh connection, which is not "ssh-remote + integrated terminal "
and after ssh connection, we get proper $DISPLAY
and copy it to our "ssh-remote + integrated terminal " to make display work.

$DISPLAY is dynamic in ssh connection so above procedure is mandatory.
if you think this situation is weird, please care.

Could you check wether remote.SSH.enableX11Forwarding is enabled?

from vscode.

also remote.SSH.enableAgentForwarding

from vscode.

Hi, I'm here to post sorry text.

two configurations are all enabled,
remote.SSH.enableX11Forwarding
remote.SSH.enableAgentForwarding

but, after restarting remote for test, "ssh-remote + integrated terminal" works with no problem.
it creates proper $DISPLAY variable and everything works fine.
maybe it was just initialization problem in remote server.

from vscode.

May I close this issue?

from vscode.

You may.
