I have a KM400 motherboard that has worked well with low latency on Ubuntu 8.04 and with the video driver set to vesa, about 10,000 ns. I just "upgraded" to Ubuntu 10.04 and the latency is really bad with any video driver, about 200,000 ns. I also have an Intel board that would not work with 8.04 but works fine with 10.04. This just shows that even with the "right" motherboard, one may still have trouble and tracking these problems down can be a real pain. The wiki has a trouble shooting page that may help. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Latency-Test http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Get your Android app more play: Bring it to the BlackBerry PlayBook in minutes.
