Hey Gilles,
Trying a different PCI slot is indeed one of the first things I considered.
The problem was simply that I was looking for another 32bit PCI slot. I was
not aware of the fact that the 32bit card works in a 64bit PCI slot.
We haven't tried setting NoAccl in the xorg.conf. But thanks for reminding.
We will give it a try and let you know how it goes. The problem is somewhat
that besides some real-time control loops we also would like to visualize
some graphics that visualize some sensor information in non-real-time. Are
there any other known issues with this setting besides latency ??
THANKS,
peter

Hi Peter,
good news. Moving the card in the slot was what I was among the things I
was thinking about when I suggested you to look at the FAQ. So,
apparently, I was not precise enough. The same goes for the X issue,
when I told you to look at the TROUBLESHOOTING guide, the
TROUBLESHOOTING guide suggests to use "NoAccel" in the X server
configuration. Did you try that?
Regards.
