X11 Forwarding in PyCharm

Hi,

I have a Raspberry Pi as a remote machine and a Windows Machine running PyCharm. On the windows machine I have installed a XMing server.

I can login to the Raspberry Pi via putty and enable X11 forwarding. If I then run a simple matplotlib script, I get the plot on my Windows machine.

I would like to achieve this setup with PyCharm. Therefore I need to know, how I can enable X11 forwarding in PyCharm. I read that it suffices to put the -X switch to the ssh command: e.g: ssh -X but I don't know how to do this in PyCharm?

In another thread here on the forum I read, that it's enough to set the environment variable DISPLAY=192.168.0.18:0.0
I did this but then I get this error:

Backend TkAgg is interactive backend. Turning interactive mode on.

The IP Adress and the Display number are correct, I verified this with putty....

Has anyone running a setup like this and it is working?

Kind Regards,

Hi Markus, I run into same issue when using PyCharm.

Have you found a solution?

It's quite annoying to always have another ssh terminal running for forwarding X11.

I'm surprised this feature is not implemented after so long.

Hi,

No, I am using Moba XTerm for now but as you said, it is very annoying.

Please vote here: https://youtrack.jetbrains.com/issue/PY-13869 perhaps we get heard ;)
