Cannot enable GPU acceleration

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 1.9.0
• Platform / OS version: Linux version 4.15.0-39-generic (buildd@lgw01-amd64-054) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3))
• Node.js version: v10.10.0

What steps will reproduce the problem?

1. Run code given below that opens chrome://gpu page + takes screenshot

const puppeteer = require('puppeteer');

(async () => {
    const browser = await puppeteer.launch({ args: ['--headless'] });
    const page = await browser.newPage();
    await page
        .goto('chrome://gpu', { waitUntil: 'networkidle0', timeout: 20 * 60 * 1000 })
        .catch(e => console.log(e));
    await page.screenshot({
        path: 'gpu_stats.png'
    });
    await browser.close();
})();

1. View resulting gpu_stats.png screenshot

What is the expected result?

Same result as in Chrome browser, in my case:

What happens instead?

This is the resulting screenshot:

I’m mainly concerned with the WebGL: Software only, hardware acceleration unavailable vs. WebGL: Hardware accelerated but at reduced performance, as I would like GPU acceleration for OpenGL rendering.

–use-gl=desktop didn’t work for me. This did.

  const browser = await puppeteer.launch({
    headless: true,
    args: [
        '--use-gl=egl'
    ]
  });

@giokara Chrome headless currently relies on software WebGL by default. You can override this using the --use-gl=desktop flag; for example, the following works for me:

const puppeteer = require('puppeteer');

(async () => {
    const browser = await puppeteer.launch({
      headless: true,
      args: ['--use-gl=desktop'],
    });
    const page = await browser.newPage();
    await page
        .goto('chrome://gpu', { waitUntil: 'networkidle0', timeout: 20 * 60 * 1000 })
        .catch(e => console.log(e));
    await page.screenshot({
        path: 'gpu_stats.png'
    });
    await browser.close();
})();

More on the --use-gl flag could be found in Chromium sources: https://cs.chromium.org/chromium/src/ui/gl/gl_switches.cc?type=cs&q=kUseGL&sq=package:chromium&g=0&l=69

Hope this helps.
