During video playback video is slightly choppy NVIDIA 8800GT

Asked by frozendice

I'm totally new to linux. I installed the NVIDIA driver which ubuntu recommended right after I installed the OS (NVIDIA accelerated graphics driver (version current)[Recommended]) for my NVIDIA 8800GT. Then I got my dual monitor setup working using nvidia-setup. I had to overwrite what was in /etc/X11/xorg.conf originally because there was some parsing error.

Is this sort of choppy playback expected? The only video I've tested it on so far is flash, so it could be that. Any ideas or hints are welcome.

Can you give the output of:

lsb_release -a; uname -a; dpkg -l | grep flash; dpkg -l | grep gnash; dpkg -l | grep swf

Also what browser do you use?

Thanks

Output of that command is:

The issue presents under both Firefox and Chrome. I can even see it when I'm watching something on youtube with full screen and a high quality video.

ok you are running a 32bit OS which makes life a lot easier.

I suggest you run:

gksudo gedit /etc/X11/xorg.conf

add this code:

Section "DRI"
    Mode 0666
EndSection

Save the new file and close gedit, then run:

sudo mkdir /etc/adobe; gksudo gedit /etc/adobe/mms.cfg

add this line:

OverrideGPUValidation=true

Save the new file and close gedit, then run:

sudo apt-get --purge -y remove flashplugin-installer; sudo apt-get --purge -y autoremove; sudo apt-get clean; sudo apt-get install -y flashplugin-nonfree

Then reboot, should be a bit better.

So I just edited the files, ran the commands and rebooted. Unfortunately the problem is still there, I don't really see any difference.

From what I can tell it looks like I just uninstalled the standard flash plugin and downloaded a closed source version. I did have chrome open playing some video while I ran the commands. Do I need to re-run and restart with all flash closed?

They help flash run better in general. Yes you will need to restart the browsers after the plugin reinstall to reload the plugins.

I've haven't had any problems with ubuntu till last week. My video is really choppy (specially with youtube) and the cpu usage is very high (near 100%). I've changed video cards (nvidia) and downloaded the appropriate drivers but no change.
Yesterday I went to a friends house who also has ubuntu and he has the same problem which recently has cropped up. He has Ubuntu 10.04 and I had the same. Now I have erased my hard drive and installed 10.10 with the same results. Any help would be greatly appreciated. I have a Celeron D 2.66 ghz cpu with 1 gig of memory.
thanks, Jim
