no DISPLAY environment variable specified

[c4artisan]

when i try to run firefox i get this error. trying to set the variable manually won't do anything.
chromium will throw "missing x server or $display"
any ideas?

most of these errors happen with both regular systemd and bottle-imp
i've tried multiple solutions and none of them worked

I'll leave this open for now, but let's keep the discussion in one place at microsoft/WSL#8899 .
