Video tearing

Hi all,

I currently have two laptops running Arch Linux. An old Core Duo (not even Core 2 yet) with Intel 945 chipset, and a Sandy Bridge i7.
Both are running Arch Linux, with XFCE, without Compiz or any fancy stuff. But to be sure I also tested on Gnome3.

On the old one, even with the bad performance (945 is the worst Intel chipset ever), everything runs fine. But on the i7, there is a lot of tearing on video playback. No matter if I am using Flash, Mplayer, VLC...

libva is installed, all Xorg, codecs and player packages are up-to-date.  I tried to add the recommended CLUTTER options on /etc/environment, it is now better than before, but the tearing still exists.

Does anyone have any idea of what can I do to fix this?

Thanks,
R.

Re: Video tearing

AFAIK, the Clutter environment variable is only applicable to Gnome.  For XFCE try running Compiz to enable v-sync.  Works for me with a Sandy Bridge i5.  Make sure Compiz is running correctly by rotating the cube.  If not, try reloading the Window Manager from the Compiz Fusion Icon menu.

The Sandy Bridge does not support xvideo overlay, but uses textured video instead (contrary to the 945).

Thanks, David. I'll try to install Compiz and see if it works.
