Extremely choppy video playback

Flash isn't owned by Shockwave and hasn't been for ages. It is now owned by Adobe and has been since 2005!

Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a; lsb_release -a

Thanks

Lol you must be getting sick of all my questions. The only reason I said Shockwave was because that's what it says when it crashes. (shows how much I know) Once again, thank you. Here's the info:

Ok and the output of:

dpkg -l | grep nvidia

Thanks

ii nvidia-common 1:0.2.35 Find obsolete NVIDIA drivers
ii nvidia-current 280.13-0ubuntu6.1 NVIDIA binary Xorg driver, kernel module and VDPAU library
ii nvidia-settings 280.13-0ubuntu2 Tool of configuring the NVIDIA graphics driver

kinda old, ok run:

sudo apt-get --purge remove nvidia-settings nvidia-current

sudo apt-get --purge autoremove

sudo apt-get clean

Then reboot and run:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

sudo apt-get update

sudo apt-get install nvidia-current

Reboot, you now have the 295 driver.

Well, I tried that, but it didn't seem to do anything. Maybe it is my old hardware. One thing I forgot to mention was that when I play a DVD, even though it's nowhere near as bad as online videos, it is still a little choppy. I don't know whether I should just give up on this dinosaur or maybe upgrade it a bit.

Tried with Unity2D session?

OK, another softball question :what do I need to do to get Unity 2D? I try to log in to a 2D session and it just doesn't seem to accept my username and password. When I finish tping the password it just brings up a blank username space again.

Log off, click the cog near your username and choose a different session. Do they make a difference?

I don't know where that cog is. When I log off the only tings on the screen are desktop choice and language choice. There is nothing else to click on. Unity 2D is not even one of those desktop choices, but there is Lubuntu (I think) 2D

Please press on little Ubuntu at right of you login name, and select Ubuntu-2d

Sorry I took so long to reply, my keyboard kicked the bucket and I had to get a new one. Anyway, just for kicks the other day, I decided to install Mint 12 LXDE. I hope that's not hated by Ubuntu users, not sure if it is considered a hated rival or just another flavor. Anyway, after booting from the CD, the video playback seemed much better, so I completely got rid of Ubuntu and kept Mint. Now I have no problem with playback. I'm assuming there must have been something off in Ubuntu, and it may have been something I did, but in either case, it's fixed. Thank you everyone for all the help.

Its not hated, just not supported in the Ubuntu channels :)
