I tried one more time from scratch. I used Xenomai 2.6.0 and the kernel Linux 2.6.38.8. The only changes I made in the configuration are the suggested in the page you send me (_CPU_FREQ, _APM, _ACPI_PROCESSOR _INTEL_IDLE, _PCI_MSI), I also disable _CC_STACKPROTECTOR and in the Preemption Model i choose "Preemptible Kernel (Low-Latency Desktop)". I have a i3 processor so I choose the Core 2/newer Xeon's Processor family. I got the same result (black screen with the sistem apparently working behind like I said), I realise that I didn't follow the recomendations mentioned in this page http://kernelnewbies.org/KernelBuild, because I tried to follow this tutorial http://www.blaess.fr/christophe/2011/12/28/xenomai-2-6-0-sur-ubuntu-11-10/ . So tomorrow I will try to do this on my own with newer versions of the kernel and probably with xenomai 2.6.1. Before that I would like to know if the configuration parameters I choose are ok, I don't know how to get a list of all of the parameters to put it here but the only changes I made are the ones listed above. I have doubts with Preemptible Kernel option because it wasn't listed on the page, so I really don't know what is the cause. If it's not a configuration issue, could be other causes to my problem?? ... I hope not, because at least it's delimited. Thank you very much for your help and please don't give up with me :) Best Regards.
