Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

After the update to "Google Chrome 20.0.1132.47" google-chrome started to lag. It gets stuck for couple of seconds and then it resumes. The issue seems to start after I enter any flash site

Running google-chrome from terminal results in following errors:

ALSA lib pcm_dmix.c:957:(snd_pcm_dmix_open) The dmix plugin supports only playback stream

Firefox does not have any problem. Can you suggest a workaround to get Google Chrome to work as it previously did?

There is a feeling that the new Pepper Flash is causing problems for some users of Chrome 20. The suggestion is to start Chrome with the following switch: --disable-bundled-ppapi-flash. You can look at this thread for more and this bug page. –  user25656 Jun 30 '12 at 15:08

Could someone comment why this is off-topic? Seems perfectly reasonable to ask here, as it's a "real" problem that someone is having, not opinion-based, and is for Ubuntu not a competing flavor. –  Ed Griebel Sep 11 '12 at 14:50

I found this to be on-topic. –  Bryce Oct 5 '12 at 19:38
    
An explanation for why this widely-approved question is off-topic would be especially appropriate now that it has at least one delete vote. We should not delete a question if the reason it was closed is still not clear to the community. "Running third-party applications on Ubuntu" is explicitly on-topic in the FAQ. –  Eliah Kagan Oct 10 '12 at 14:59

I'm having the same problem when using the Chrome version of Flash Player. Temporary workaround:

  1. Install the adobe-flashplugin package
  2. In Chrome, go to: chrome://plugins/
  3. Disable the /opt/google/chrome/PepperFlash/libpepflashplayer.so instance of Flash Player
  4. Restart Chrome

This worked for me too. Chrome was unusable before doing this where it would be 1-2 seconds before it responded to any input (mouse click, keyboard, mouse wheel). It is now acting fine. –  Ed Griebel Sep 11 '12 at 14:52
    
Seems to work fine here, too. Should I expect any adverse side-effects after disabling libpepflashplayer.so? –  Mikko Rantalainen Oct 10 '12 at 10:43
