I am having major choppy flash video playback issues with Ubuntu 11.04. The issue only occurs while playing flash video. It works fine in regular video playback (divx/xvid).

I have and have tried the following:

  • ATI Radeon 4200 (integrated graphics)
  • Using Latest ATI/AMD Proprietary Driver FGLRX
  • Ran Update Manager
  • AMD X4 630 CPU
  • Played flash video in 360 quality
  • Latest version of 64-bit flash beta installed
  • Flash-Aid installed on Firefox
  • Tried in both Firefox and Chrome, but still laggy.
  • Attempted to make a new user account, and tried it on there, but still doesn't work.


  • it's flash, what did you expect?!

  • @AsianXL - is it just youtube flash you have issues with? Have you tried youtube html5 videos ?

  • fossfreedom - Thanks for the prompt response. I am actually not having any video playback issues on Youtube, rather I am having problems playing flash video on other video sites.

  • I guess I would say there is a reason for get-flash-video.

  • get-flash-video doesn't work on the video site that I am watching from.

Try disabling hardware acceleration in flash. Worked for some YouTube videos for me on my ATI HD3000 series graphics card. HTML5 is the way to go though

  • Thanks, I'll try that on other videos. It didn't appear to work on the site that I'm having problems with.

Try using gnash instead of Flashplayer. To install gnash sudo apt-get install gnash . I have used it for over a year and gnash seems to work better than flash.

If you feel better uninstalling flash then installing gnash you can do this by opening terminal

sudo apt-get purge flashplugin-nonfree flashplugin-installer gnash gnash-common mozilla-plugin-gnash swfdec-mozilla

sudo rm -f /usr/lib/firefox-addons/plugins/libflashplayer.so

sudo rm -f /usr/lib/mozilla/plugins/libflashplayer.so

sudo rm -f /usr/lib/mozilla/plugins/flashplugin-alternative.so

sudo rm -f /usr/lib/mozilla/plugins/npwrapper*flash*so

rm -f ~/.mozilla/plugins/*flash*so

sudo apt-get install gnash

  • Is entering that code all I need to do? Any other settings I need to tinker with?
