[Xenomai] Trouble with Xenomai - Desktop issues

[Xenomai] Trouble with Xenomai - Desktop issues

[Ankit Goila]

Hello friends,

I am working on setting up my machine for real time capability using
Xenomai. The specs are: Intel Xeon CPU (with 8 cores), Ubuntu 12.10
(Linux-3.5.0-17-generic).
Recently, I installed Ubuntu 12.10 on my machine and configured it for
Xenomai 2.6.2.1 kernel, following the instructions given on this page:
http://www.stanley.gatech.edu/skelly/uncategorized/installing-xenomai-on-ubuntu-12-04/#comment-932

I was successful with the setup and the grub menu shows the xenomai kernel
installed. But, on booting into the Xenomai option, a desktop is displayed
without any menu/task bar etc. The PC freezes upon booting, with no
internet connection available. Here is the screenshot of the post-boot
screen. I think this might be a problem with configuring the kernel, but
then there are no set rules for configuration for a particular machine. I
will be really grateful if somebody could help me out here.

Hi Ankit,

Want to give some pre-compiled Debian packages a try?  See here:

http://wiki.linuxcnc.org/cgi-bin/wiki.pl?XenomaiKernelPackages

Also, if your NIC happens to be the r8168, you should compile that
driver separately.  There's a Debian package for that one as well,
pointed to in the above link.

Hi John,

Thanks for your reply. I currently have Ubuntu 12.10 installed on my
machine. In order to use the pre-compiled packages, do I need to just
compile the code given online through the command line? Or do I need some
other packages as well? The Ubuntu currently has the kernel version
3.5.0-17-generic.

Regards,

Ankit

Hi Ankit,

Please read the instructions on the webpage linked to in the previous
email.  I believe you should be familiar with installing software
packages on Ubuntu, where no compilation is necessary.

For Ubuntu 12.10 you should use the 'precise' debian archive, so

  CODENAME=precise

then follow the rest of the instructions as usual.

Also take a look here, and avoid top-posting on this list:

Hi John,

I tried the Linux CNC pre-compiled packages mentioned in the link above, I
followed all the instructions as per the article. On reboot, I am able to
access the desktop from the Grub menu, however, the keyboard and the mouse
are unresponsive. In a way, I can see the desktop, everything as such, but
am not able to provide any input. Is this a configuration issue? Or is it
with the drivers?

Very unlikely either.  The dozen or more systems I'm aware of on which
these packages were tested never exhibited such symptoms.

There are a great many things that happen between the grub menu and the
point where one may 'access the desktop'.  I won't be able to hold your
hand through learning about those.  I suggest you do some basic
troubleshooting on your end, starting with checking system logs and
configuring grub and the kernel not to hide console messages and init
not to start graphics.

When you're at the point where you've captured and analyzed the various
sources of diagnostic output, googled error messages, and are still
stumped, copy the relevant output to a pastebin and ask again here.
That might increase your chances of getting help.
