Can't run/debug within vscode

Frustratingly, I can’t get my code to run from within vscode, so I’m not able to debug within vscode which is slowing down my development…

The issue arises when I try to initiate vedo.plotter.Plotter() when running from vscode, when I get this error:

ERROR: In /work/standalone-x64-build/VTK-source/Rendering/OpenGL2/vtkXOpenGLRenderWindow.cxx, line 1223
vtkXOpenGLRenderWindow (0x5587f7b42cf0): bad X server connection. DISPLAY=Aborted (core dumped)

If I run the same code directly in terminal, it runs fine, so this is an issue with the way vscode is configured, but I can’t find any answers online.

This seems to be an issue on all vscode installations I have running on Ubunut (in this case 20.04). Here’s the vscode info:

Version: 1.51.0
Commit: fcac248b077b55bae4ba5bab613fd6e9156c2f0c
Date: 2020-11-05T18:16:10.374Z
Electron: 9.3.3
Chrome: 83.0.4103.122
Node.js: 12.14.1
V8: 8.3.110.13-electron.0
OS: Linux x64 5.4.0-52-generic snap

Similarly, I’m unable to open up browser windows from vscode (for example plotly fig.show() and selenium driver = webdriver.Chrome(chromedriver) won’t open browser windows. I get the following error with selenium:

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally.
  (unknown error: DevToolsActivePort file doesn't exist)

Similarly, this works fine direct from the terminal.

I’d really appreciate any help!

Seems the issue is with the default console setting on vscode and changing it in launch.json fixed the problem, in my case to externalTerminal with the Terminal > External: Linux Exec setting set to the default x-terminal-emulator.

Here’s my launch.json settings:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "externalTerminal"
        }
    ]
}

Hope this helps anyone else who may be dealing with similar issues.

Thanks @marcomusy. I tried installing that package but it doesn’t change running in vscode unfortunately.

You’re correct, this is not an issue with vedo.
