chrome://gpu/ was the only thing that worked for me. 'chromium' or leaving off the trailing slash just dumped me into google search results. Don't know if that is significant. :-) I'm running $ chrome --version Chromium 35.0.1916.155 $ on an amd64 desktop. '--ignore-gpu-blacklist' does seem to enable the youtube video I tried. But as pirofti@ says, it doesn't stick for me. And typing has become *very* slow. I feel like I'm using a 300baud modem as I type this into gmail. :-) .... Ken
