something relies on X-display - not sure what

[zbenmo]

When I start the bulk server, something is not progressing. This was with text. If I have X display available, everything is like a breeze.
Not sure where it is. I'll add more information if I have.
I had a similar issue in the past, this was solved by something like: mpl.use('Agg')

What is an "X display"?

Could you apply markdown such that it renders as code? Makes it easier to read.

Re: X display. I work on a Windows machine, with WSL2 (Ubuntu). Then I need to run XLaunch on Windows before running bulk. Otherwise it will not work. Don't see a real need for X, given that it is a web server. matplotlib may try to use X, but that can be overcome with mpl.use('Agg'). Maybe a plotly issue as I've really just tried bulk with texts.

[koaning]

Bulk uses bokeh under the hood, so if there's issues/fixes, I'd recommend checking their repo/community.

[zbenmo]

Checking with them. Will update.

[koaning]

I'll close this issue for now, but if it later turns out that this is a specific issue related to bulk -> feel free to re-open.

The problem was that 'bulk' is attempting to open a browser. It may not be a bug but rather a feature. Up to you to decide. Good to know. Maybe nice to have --no-browser. Apologies. BR. Oren.
