Nils, I've tried these various options and always run into issues with
getting SOUND to work in the end. With 6.0 it was ridiculously easy.

If only I could get the Pulse Audio sound volume applet to work in 6.0 then
I'd be really happy. Any tips from anyone??

Tom

P.S.1. We run a K12LTSP 5EL server with 64-bit Firefox and
nspluginwrapper to be able to use the 32-bit Flash Player. That works
fine, but I don't know about sound (and whether the whole 64-bit
versus 32-bit thing has anything to do with it).
P.S.2. Others just install Firefox 32-bit on their 64-bit OS and that
apparently works just fine as well. Don't know if that helps with
sound though.
P.S.3. Apparently Opera 9.5 will support running the 32-bit Flash
Player plugin under the 64-bit version of Opera out-of-the-box.

Message-ID: <20080127192518 GA6919 hank org>
Content-Type: text/plain; charset=us-ascii

I've seen a few use-cases where some claims are made on cost savings
using LTSP.  I'm curious if anyone here has looked at this recently at
their own schools.

I was looking at thin clients the other day, and although I'm not sure
the very inexpensive $85 Norhtec clients have enough power, it's
looking like $150-$200 clients are possible.

Our school is considering one option of using the Mac Mini for the
student workstations.  So potentially, that's $400+ savings up front
per seat if using something like a $200 thin client.  Actually, that
might be an underestimate considering that the thin client hardware
would probably have a longer duty cycle than stand-alone workstation.

Of course, it's not that hard to come up with donated PCs, so that's a
bigger savings.

Software purchase, upgrades, and licensing seem like another
significant per-seat expense.  I assume most schools migrated from
Windows, but the licensing requirements might be similar to Apple.
Anyone have any numbers in this area?

Energy savings might be a consideration, too.  Some of the thin
clients have very low power consumption.  Swapping out 100 PCs with
300 watt power supplies to 100 thin clients that consume 10 watts
might not be a huge difference in cost but not insignificant.

Finally, it's hard not to imagine the management of 100 thin clients
is significantly less than 100 workstation.  Still, I doubt that often
results in any savings.  Rather just a change in admin tasks.  Have
you realized any quantifiable differences in management costs?

Anything else?

Has anybody on the list had success running Firefox for Windows under wine, and getting Flash to work that way?

I am running IEs4Linux (from

server, but it's 32 bit and it's not through a thin client...
Sound/Flash works fine - will try it on a CentOS5 64bit this week,
running via Symbio Thin Clients, and perhaps we have a temp solution...

How about just running 32-bit?  You can run the HUGEMEM kernel with PAE
extensions if you need more than 4GB DRAM (assumes Intel CPU's for PAE,
of course).

Been there and done that. Yes, flash-with-sound worked, PAE worked, but
there were other issues with Edubuntu that drove me nuts. Thanks for the
tip though.

Hello List,

i am using Ubuntu Server 6.06 with the smbldap installer script from
majen.net/smbldap/
I use VMWare to run my test systems (Ubuntu server and Windows Domain
Clients)

After producing a power supply failure (stopping my Ubuntu and windows
client by the stop button in vmware) and starting them up again i can
see a delta/change in my ldap database:


Before Power failure:

I did not manually change those properties and i wonder who or why they
changed.

The result is that my windows client can not log into the domain
anymore. I have to remove it fro the domain and add it again.

Has anyone an idea why this is _automatically_ happening?
Why, who or what can change those machine attributes?

Still having issues with both Sabayon and /etc/skel. When I try to edit a sabayon profile I get this terminal printout.

Any ideas on troubleshooting this? Also /etc/skel sticks to a user I create locally, but not to one that has it's home directory created by pam_mkhomedir and is authenticated against AD. Thanks!
