Youtube flash player slow and laggy in Ubuntu 12.04 LTS

[Cerberus90]

So I've had the same problem as a lot of people, youtube was extremely laggy even when I played 240p videos and I tried everything, html5 youtube, flash-aid plugin for firefox and whatnot, and they didn't work for me.
Then I enabled "Override automatic cache management" on firefox. It got a little better but still a bit laggy on fullscreen.

Then I thought I'd let Ubuntu use more cache . So if you have the same problem just try this:

sudo gedit /etc/apt/apt.conf.d/70debconf.

Then put this code,:
APT::Cache-Limit "100000000";
on that file and then save it.

Next type this code on your terminal
sudo apt-get clean && sudo apt-get update --fix-missing
and you won’t find apt cache limit again in the next time.

It worked for me!!!

What command do what and it is make my videos even worst! I try 3 times this and nothing is better !

You, Sir, are a star!!!

If I had a prize to give you, I would. But, I can only give you my thanks for enabling me to finally watch 1080p video on my machine.

Thanks again

Well... it's worked for a few people, already... I didn't know computers were also susceptible to placebo. hehe

I'm also having problems with flash player in both of my ubuntu systems. They get laggy in youtube, flash games, etc.

Does anyone know of a solution unrelated to placebo? haha

Without really digging into the internals of apt, I wouldn't completely rule out that this is a placebo because it does improve my firefox youtube viewing as well. Full screen was not usable at all earlier but now, while not perfect, is much better. It could be that it has nothing related to cache, but simply, the process cleans up some dirty links left over by the flash plugin installation.
