yes, this seems relevant too: [Generation of documentation fails: "qt.qpa.xcb: could not connect to display"](https://discourse.julialang.org/t/generation-of-documentation-fails-qt-qpa-xcb-could-not-connect-to-display/60988)

I added `GKSwstype: "100"` to my `ci.yml` file… let’s see if this solve the problem. Thank you.

[EDIT]: yes, that solved my issue.
