I'm trying to get Google Lighthouse CLI work on my Debian server. I use the following instruction to run headless Chrome: https://github.com/GoogleChrome/lighthouse/blob/master/docs/headless-chrome.md#cli-headless
It installs fine, but when I do:
lighthouse --chrome-flags="--headless" https://github.com
I see this:
ChromeLauncher Waiting for browser. +0ms
ChromeLauncher Waiting for browser... +0ms
ChromeLauncher Waiting for browser..... +505ms
ChromeLauncher Waiting for browser....... +501ms
ChromeLauncher Waiting for browser......... +501ms
ChromeLauncher Waiting for browser........... +501ms
I also tried this way: https://github.com/GoogleChrome/lighthouse/blob/master/docs/headless-chrome.md#cli-xvfb
But it results in the following:
# xvfb-run --server-args='-screen 0, 1024x768x16' chromium --user-data-dir=$TMP_PROFILE_DIR --start-maximized --no-first-run --remote-debugging-port=9222 "about:blank"
Xlib: extension "RANDR" missing on display ":99".

Is there anything I'm missing on the software side, or Lighthouse cannot be run on Debian server at all?
Anyway, I ended up using PageSpeed Insights API instead: https://developers.google.com/speed/docs/insights/v5/get-started
It produces the same JSON that Lighthouse CLI does, but you don't need to setup Chrome or anything, it's just a HTTP request.
