Hello all I have an issue when running an example in openlane. There is no source to find a reference. Anyone used to have the same issue ?

This is probably X11 issue. You need to set your DISPLAY variable and make sure you have an X11 client running.

Thanks David, I already installed X11 and tested with some basic command such as "xlock" or "xeyes", and it works. I don't think this issue is because of X11 client.

You’ve tried

xeyes

in the Openlane Container?

Actually no, I tried on terminal. You mean xeyes should work on Openlane Container ?

Openlane Container is where you’re trying to start klayout, right? Can you start klayout in the terminal?

Yes, I am trying start klayout from openlane container (is this way correct ?). I can't open klayout in the terminal.

Setting up X11 in the container is a little different than the terminal. I think it can be done, but I’m not sure how. I believe there was a slack discussion about it. You could try installing klayout native to your terminal.
