I just tried out Edubuntu 10.04...
It has something new called LTSP live...
Now my problem is, it doesn't work...
In the meantime, I've gotten it to work somewhat. I checked the MD5 sum of my
DVD+RW and found errors, so reburned my DVD, using a DVD-RW at single speed
this
time, resulting in a correct MD5 sum. LTSP-live still doesn't work as intended
and seems to mix up eth0 and eth1 sometimes, but if you *repeatedly* run it
*while* a thin client is running and waiting for DHCP offers, and trying out
both eth0 and eth1 irrespective of actual network cards and routers present, it
should eventually work - as a last resort you can try rebooting. It is possible
to have a terminal server and thin clients running completely live within 10
minutes, perhaps 5 minutes with fast machines! ( I know Knoppix has done this
for years, but I never figured out how to.)
Booting the thin client takes rather long, almost as long as building LTSP
itself, but with newer monitors you get automatic resolution configuration and
the possiblity of changing the orientation on the thin client. In my case, I
was
able to use the 1600x1200 screen upside-down (very useful if you want to mount
your monitor from the ceiling but I wish there was a mirror-image option
instead), but portrait mode didn't work and crashed X, as unfortunately the
default is to continue with the new settings instead of resuming the old ones.
I'll try to mention these in Launchpad.
With an old monitor, Edubuntu apparently tries to use either the same
resolution
as the server on the thin client or perhaps the maximum resolution that the
thin
client provides - but the server seems to get 800x600 if its monitor isn't
recognized, with no possiblity to change this.
The multimedia stuff works perfectly!
Edubuntu uses Gnome as default and has discontinued the previous rather nice
but
juvenile look. This also makes it easy to get a KDE 3.5 type of look very
quickly (take the top bar to the bottom, make it a bit bigger and delete the
previous bottom bar)) and one KDE 4 program (Marble, including OpenStreetMap)
is
preinstalled.
The thin client is now also supplied with a mini-boot manager allowing to boot
an installed or embedded system instead of the network system, without having
to
remove the ethernet cable first.
Summary: Apart from bugs, you can now get a terminal server running from
scratch within minutes, thus installing an entire computer classroom
instantly and if desired temporarly. Well done, developers!!
