Not quite. It's true that Ubuntu Studio is pretty close to our original
design for the 64 Studio distro. We were offered the possibility of a
merger by a former Ubuntu Studio project leader, but that would have
meant them being in charge and us doing the work.

As far as I know, Ubuntu Studio has technical support but no actual cash
funding from Canonical, and I think that's been the case from the
beginning of that project.

These days, our focus is not on a general-purpose creative distro,
because Ubuntu Studio and other similar projects like AV Linux provide
that. Rather, we use our distro customisation tools to create niche
products, like musical instruments, mobile devices and audio research
equipment.

There will be more free download audio/multimedia distros available from
us though, because we need to stay very close to the community that
we've helped create.

Cheers!

Daniel

So if a 64-bit Debian or Ubuntu based Linux is wanted, than a user might
be more comfortable to use Ubuntu Studio, but 64 Studio? Or using Ubuntu
Studio 8.04.1 (Hardy) + the 64 Studio 3.0 repository, resp. Ubuntu
Studio 9.10 (Karmic) + the 64 Studio 3.3 repository?

My plan for today was:

"I scheduled to get 64 Studio 3.0 and 3.3 from my broken hard disk
drive, by using a hammer or something softer, to free the heads, when
they do this click-click sound, but because the postman delivered the
second sound card I'm too curious, so I'll restore at least 3.3 from a
backup, to my new hard disk drive and delay the original plan."

Hm, maybe I'll completely delay to restore 64 Studio, but should take a
look at Ubuntu Studio 10.04 (Lucid)?!

I dunno what I'll do. At the moment it's to hot in the room, so I'll
turn of the computer and leave the room.

Cheers!

Ralf

Hi Mike,

I've tried the group registration a couple of times, but nothing ever
happens. I guess it won't hurt for me to try again

That's very kind, thanks. If there are community members who would be
interested in hanging out on #64studio and helping (or just chatting
with) other users, that channel would certainly be a useful facility to
have.

I'd admit that we haven't done a very good job of communicating with the
user base about our plans and roadmap lately, but I'm hoping we'll be
able to announce some new stuff soon which will put all this into context.

Cheers!

Daniel

No it isn't. I experienced that non of the kernel-rt from the repository
is boot-able. By default they install not a kernel-rt. I couldn't build
a kernel-rt that is boot-able.

Yep, I just wanted to underline that at the moment this are two cards,
but one virtual.

Unfortunately no kernel-rt is boot-able for my Ubuntu Studio 10.04. If
64 Studio isn't continued, I don't know any good DEB based audio Linux
for 64-bit architecture. AV Linux seems to be good, but is released only
as i386.

Hm, perhaps OT for this list:

I wonder if anybody run Ubuntustudio 10.04 with a kernel-rt.
Building a kernel failed.
And all kernel-rt from the repositories failed.

$ cd /usr/src
$ sudo synaptic
  I checked if those packages were installed:
  bin86
  build-essential
  bzip2
  fakeroot
  gcc
  kernel-package
  make
  libncurses5-dev
$ wget ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.33.5.tar.bz2

$ make-kpkg clean

  This didn't work:
  $ make-kpkg --rootcmd fakeroot --initrd kernel-image kernel-headers
kernel-source
    50 minutes later
    make[5]: *** [drivers/staging/comedi/drivers/quatech_daqp_cs.o]

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

When I tried to boot the kernel I got

'[    0.499322] ACPI: Expecting a [Reference] package element, found
type 0
 [    0.811991] kernel panic - not syncing: VPS: Unable to mount root fs

For the entry in grub.cfg initrd is missing:

menuentry 'Ubuntu, with Linux 2.6.33.5-rt23' --class ubuntu --class
gnu-linux --class gnu --class os {
	recordfail
	insmod ext2
	set root='(hd1,11)'

	linux	/boot/vmlinuz-2.6.33.5-rt23 root=/dev/sdb11 ro   quiet splash
}

Unfortunately initrd is missing too:

$ ls /boot

'Kernels

-generic will be installed if ubuntustudio-audio meta is NOT selected

-preempt kernel will be installed if ubuntustudo-audio meta IS selected

-lowlatency kernel is also available in Abogani's PPA -
https://launchpad.net/~abogani/+archive/ppa
-realtime kernel will be available in Ubuntu Studio PPA'
http://ubuntustudio.org/LucidLynx

So I added 'deb http://ppa.launchpad.net/abogani/ppa/ubuntu lucid main'
and
'deb-src http://ppa.launchpad.net/abogani/ppa/ubuntu lucid main'. Then I
installed the rt kernel from this repository.

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

When I try to boot kernel 2.6.33-23-realtime from the repository I get
'ACPI: Expecting a [Reference] package element, found type 0' too, but
no kernel panic, instead it will boot into text mode.
