I've recently installed Xubuntu-14.04 on my VAIO-P netbook with Intel GMA-500 graphics chipset. I had several problems (as expected because of GMA-500/Poulsbo) and fortunately I was able to resolve most of them.

The last remaining problem to achieve an ideal experience is video playback quality: videos play choppy and laggy. I've tried several video players, including the default Parole, GNOME Videos (Totem) and VLC. The first two are the same and have choppy-laggy playbacks. VLC can do nothing and just hangs!

I'm testing with medium quality (480p) MP4 videos, which should be able to play fine. In Windows-7, even HD (720p) videos can be somewhat played (though not very smooth) but there is no problem with 360p or even 480p videos.

Note: I've been installing and using Ubuntu/Xubuntu on this machine since 10.10 and this is not a new problem with 14.04. In the past the problem was simply because there was no fine performing driver for GMA-500/Poulsbo graphics. But from 13.04 on-wards, many problems are gone or can be resolved easily, as I have done so myself.

So I was wondering if there is a solution for this?


Note-2: I don't know if this is related information but I also had choppy audio playback (both for videos and audio files), and I was able to resolve it using the solution suggested here, which was adding tsched=0 to the following line in /etc/pulse/default.pa:

load-module module-udev-detect

This solved the audio playback problem both for audio and video files. Now, the only remaining problem is the choppy video playback.


UPDATE: Surprisingly, Totem is now playing videos fine! I don't know what caused it to work because I didn't work on the issue since yesterday and suddenly it's working today! Although Parole is still unable to play smoothly and it's exactly as before: choppy and laggy.

I'll be using Totem (GNOME Videos) for now, but still I appreciate if anyone can help me understand what solved the problem on Totem, and how to solve it on Parole to.

There used to be a ppa repo for the GMA500 drivers.

https://launchpad.net/~gma500/+archive/ppa

They have not been updated in a while, but I made it to newer versions of Ubuntu (12.04 I think it is the latest I tried) with the one they offer there.

Another solution I took with a laptop that had that graphic card was EMGD drivers. The ppa repository is provided again by the same gma500 user in Launchpad.

They have not updated in a while :( but these solutions used to make it easy for me. Install, reboot, everything is in its place.

Thanks for the answer but those drivers were for the old days and they are now obsolete. You can read more about them in this wiki page: wiki.ubuntu.com/PoulsboObsoleteDrivers –  Seyed Mohammad May 22 at 6:06
