Hi team,

Command

@pavanseniorassociate Is your issue that Chrome never launches?

[pavanseniorassociate]

@adamraine Yes

[adamraine]

I can't repro this unfortunately, could you please provide this information:

• Lighthouse version
• Node version
• Chrome version

[pavanseniorassociate]

1. lighthouse version : 9.6.8
2. Node Version : v16.15.0
3. Chrome Version : Google Chrome 107.0.5304.110

[adamraine]

I was able to reproduce this when I removed the --chrome-flags=--headless flag, perhaps headless mode isn't being applied somehow?

@pavanseniorassociate lmk if either of these commands works for you:

lighthouse https://nodejs.org/en/ --chrome-flags="--headless"

If you have Xorg installed:

xvfb-run --auto-servernum lighthouse https://nodejs.org/en/ --chrome-flags="--headless"
