Video playing slow (full screen) - Ubuntu 12.04

Asked by Danilo Mendes Akiau

Hello, first I wanted to say that I am new in using Linux and so I may not understand some terms.
What happens is this, I have several .avi videos in my folder
I have already installed all the necessary codecs and the driver of my video card is installed and working perfectly well (ATI Mobility Radeon HD 4250)
Well, the problem is that whenever I run a video in full screen (fullscreen) by VLC or other media players, video wheel locking up, as if skipping frames, making it unpleasant and impossible to watch anything
I tested the same video in full screen in Windows 8 and it worked perfectly fine (I have Dual Boot with Ubuntu and Windows), but I wonder what happens in Linux to do the video hangs ...
Initially I thought it was the video card misconfigured but did several tests and all is right.
Detail, when I try to watch videos in full screen on youtube in HD quality 1080p the videos work perfectly well, without crashing.

Note: I'm using Ubuntu 12.04

Thanks, but the problem persist
It isnt a flash problem i think, because in youtube I can play HD videos in 1080p without lagging
Just in the VLC player the video playing with lag (in fullscreen mode) and I don't no why :(
My PC have a good processor (AMD Phenom(tm) II N930 Quad-Core Processor × 4), and 6gb of RAM, with a decent video card (ATI Mobility Radeon HD 4250)
The problem have no sense

It's strange because when I use resolution 1920x1080 (1080p) on my Monitor (it' defaut) the video lagging but when I force the screen to a lower resolution like 1366x768 and playing a video, the video don't lag...

Try:

sudo apt-get --purge remove flashplugin-installer

Enable the partner repo and install the adobe-flashplugin package

Ok, I can remove flashplugin but how I enable the partner repo and reinstall the adobe-flashplugin package? What is the command in terminal to do it?

You can use software centre to do it all
