The "base 2.7-uspace" and "base 2.7-rtai" strings in /etc/apt/sources.list indicate what components of the linuxcnc debian archive the machine installs packages from. Everyone should always include "base", and one of the version-specific, flavor-specific components such as "2.7-rtai" or "2.7-uspace". (In 2.6 they're called "2.6" for the rtai flavor and "2.6-sim" for the non-realtime, simulation-only flavor.) When you change which deb component you're accessing, 2.7-rtai or 2.7-uspace, it'll change what debian packages are available to you. You need to uninstall the previous flavor of linuxcnc and install the new one in order for the test to be valid. Looking at your screen captures, i wish latency-histogram included the linuxcnc version number and flavor in the window, along with the (very useful) kernel version string... -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
