[Xenomai] Conflict with Ubuntu 13.04

[Travis Llado]

Hi,
I'm new to xenomai and I just installed it with Ubuntu 13.04 and kernel
3.5.7. As soon as I booted 3.5.7 with xenomai, the Unity GUI stopped
working. It looks like the problem is in compiz, a plugin for Unity. Unity
can't run without it. I'm getting the exact same problem on Ubuntu 13.04 on
a macbook and a Dell desktop. Has anyone else run across this problem? I
can still run xenomai code through the terminal and I can run graphics
applications, but if I try to load compiz the whole system freezes. It
looks like compiz is persistently broken, because when I reboot into the
3.8.0 kernel that comes with Ubuntu 13.04, Unity/compiz are still broken.
Any thoughts?
Thanks

Does Unity work with the exact same kernel configuration, only without
CONFIG_IPIPE and CONFIG_XENOMAI?

If you are using nvidia drivers, not nouveau, what is missing is
probably simply to recompile them for the Xenomai-patched kernel. But in
that case I suppose your X server would not work at all.
