[LAU] xruns from GeForce 7300 GS video card

     I built a computer to run Linux and Ardour. I installed a GeForce
7300 GS video card in it. With help from Paul Davis and others on the
LAD forum, I was able to get jack/ardour/hydrogen/etc working. However,
xruns problems make these programs unusable. I think the video card is
causing the xruns, because they go away after about 15 seconds of no
motion with the mouse or files in the GUI. As soon as I move the mouse
or open a popup menu or anything else, the xruns return and sequire
several seconds to go away.
     With this card I am also getting long streams when I move things
around on the Windows desktop. The ghosting also happens in Ubuntu, but
is not as severe.
     I have read a little about changing interrupt priority at
http://lowlatency.linuxaudio.org/ , but I could use some guidance and
opinions on what to do.
     I plan on installing Ubuntu Studio when it comes out in a couple of
days.

     I have a Gigabyte GA-965P-DS3 mobo and a Pentium D-930 processor.

Thanks,

Dave
