[LAU] xruns from GeForce 7300 GS video card

[David Froseth]

     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
