impossible to open a file in a ssh session

[JujuLand]

Hi,
I frequently use ssh -X sessions to work on distant computers (on LAN or WAN).

For example, I can open a pdf file with xdg-open.
With ncursesFM, no error, but it doesn't open.

As I hoped to use ncursesFM as a file browser which uses smaller resources than a graphic file browser, I'm a little desappointed ... Too bad

Mmh ncursesFM checks for "getenv("XDG_SESSION_TYPE")".
Can you paste me the output of "echo $XDG_SESSION_TYPE" in your ssh -X session?

[JujuLand]

alain@aupeix-GX723:~$ echo $XDG_SESSION_TYPE

alain@aupeix-GX723:~$

annie@xubuntu-IMEDIA:~$ echo $XDG_SESSION_TYPE

annie@xubuntu-IMEDIA:~$

Here are the ssh versions:

I have these variables when connected:
SSH_CLIENT=192.168.1.15 42052 22462
SSH_TTY=/dev/pts/7
SSH_CONNECTION=192.168.1.15 42052 192.168.1.14 22462

If it can help ...

Can you please try to export XDG_SESSION_TYPE=x11 in you ssh -X session and retry?
The logic behind is that if no XDG_SESSION_TYPE is found in environment, it means we're running on a tty, thus ncursesFM tries to use "nano" or whatever editor is setted.
I will try to fix this logic though.

I add this variable in .profile, and it works.

Which thing, usually set this variable ?

Nice!
i think desktop manager or desktop environment usually set this variable.
For now you can use a script that export the variable before starting ncursesfm. I'll try to solve the issue though.

[JujuLand]

Adding it in profile is enough and doesn't make problem using directly xdg-open.

So do what you can.

Thanks
