I can only speak for Debian here. We deliberately don't promote it as "desktop distro". Rather as "Universal OS", to underline its use in the Server, Embedded, Realtime areas, etc. > But after I "installed" Xenomai in Ubuntu, executing "dmesg | grep xenomai" showed nothing, so I am wondering if I still need to > patch and compile the kernels before using the Xenomai features? If so, > what benefits does it have to include Xenomai in these distro's. First, you still have to compile the Xenomai-enabled kernel yourself (but this might change in the future). This is supported by the Debian-included package linux-patch-xenomai. The file /usr/share/doc/linux-patch-xenomai/README.Debian gives instructions how to prepare the kernel as a Debian package. Second, Debian ships Xenomai's userland programs and libraries, so you can use them directly, without compiling. Since Debian derived distros (as you mentioned one) typically copy the Xenomai packages from Debian, much of this should apply there also, but I can't guarantee this. HTH, Roland
