ubuntu

i have been using ubuntu for a while now, and have been comparing it to windows 7. i have noticed that in ubuntu, in firefox or chrome, streaming videoes on sites like Yahoo having what appears to be buffering problems.
for instance, i tried watching a video on yahoo, and the video was all jerky and the sound was way off sync.
so i copied the url to my win7 machine, watched the same video ( it's on the same computer because i duo boot between win7 and ubuntu 11.10 ) and it's not jerky at all and the sound is in sync.
any ideas why this is happening?

Its most likely your drivers.

Specifically I would expect it to be Video drivers, what are your system specs?

Have you installed flash? As far as I know, since flash isn't OpenSource it isn't installed by default on Ubuntu. Use your Packagemanager to install flash for your browsers.

The above questions are good.  I have another question.  What kind of video are you watching?  (streaming flash, mpeg...)?

I wonder if we could figure out if you have the Nvidia Linux driver loaded or something else.  Could you copy/paste your output from

$ lsmod

(if that doesn't work try)

$ sudo lsmod

The driver for my Nvidia Geforce Go 7600 is called nvidia.  My guess is your lsmod won't show nvidia.

Hugh McCurdyCommented:
If the driver isn't there, try this

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current

Open in new window



Then reboot.

fglrx is an ATI video driver if I'm not mistaken.  I don't see a Nvidia driver.  

Perhaps you should get a list of hardware.

$ lspci

Still, you probably want to download the Nvidia driver using the apt- commands I provided above.

Ubuntu has an applet "Additional Drivers". Just look for that. With it you can easily install the legacy drivers for things like nvidia and ATI video cards, or wireless cards etc.

wow, i'm such an idiot!
i had an Nvidia, but recently bought a Radeon HD5450
i found my Nvidia in my pile of hareware that i'm not using
so, disregard the Nvidia thing, i have a Radeon HD5450, so i guess i could try the additional drivers thing.

Hugh McCurdyCommented:
We all make mistakes.

Radeon explains why the fglrx driver loaded.  You could check for a driver update.   See if that solves the choppy playback issue.

There are other places to look but I'd have thought that Ubuntu would invisibly take care of those issues.  But one issue at a time.  Please check to make sure the driver is current.
