Finally Fixed Jerky Flash Videos in Firefox on Kubuntu 11.04!

For months, ever since I installed Kubuntu 11.04 on my brand new shiny laptop, Flash videos have been jerky and frequently crashed the whole darn machine when played full screen. The “Official” advice regarding x64 Firefox and Flash didn’t help at all, but I never managed to get around to Googling the problem and finding a solution… Until now!

FlashAidSeveral threads on Ubuntu Forums suggested the Flash Aid Firefox Plugin, with many people reporting success. Now I am one of them! Although I didn’t achieve success at first, I had to do the following:

  1. Install FireAid plugin
  2. Restart Firefox
  3. Run FireAid Wizard
  4. In a command terminal, type:
    sudo apt-get remove --purge flashplugin-nonfree
    sudo apt-get remove --purge flashplugin-installer
    sudo apt-get remove --purge flashplugin64-installer
    sudo apt-get autoremove
    sudo updatedb
    sudo mkdir /etc/adobe
    echo "OverrideGPUValidation=true" >~/mms.cfg
    sudo mv ~/mms.cfg /etc/adobe/
  5. Reboot

Really I probably did it backwards and should have done 4 and 5 before 1, 2 and 3, but nevertheless it worked :)

Bowden Extruder Troubles

Our Huxley hot end kept popping out from the clamp, which was warping under the heat, and ramming into the print bed gouging out designs in the plywood.

Several iterations of clamp design later and we’ve settled on a beefed up version that seems to cope with the force of the extruder (even when I had set the Z STEPS_PER_MM to 20% of what it should have been). Continue reading Bowden Extruder Troubles
