How to launch Chrome with explicit "hardware acceleration" setting?
Solution 1:
Your own answer is correct. The only thing is that this only changes the setting for the current execution and does not affect your preferences. I say this because I had issues running chrome with the setting enabled (https://productforums.google.com/forum/#!topic/chrome/7D3P84WKqew;context-place=forum/chrome), and the only way to get around it was to launch using the command yuo provided and then go into settings and disable it.
