K12LTSP 5.0 is based on Fedora Core 5, which includes all sorts of
new stuff. Of primary interest to K12LTSP users:
* This release of Fedora includes Mono support for the first time,
and Mono applications such as Beagle, a desktop search interface;
F-Spot, a photo management utility; and Tomboy, a note-taking
* There is dramatically improved internationalization support with
SCIM in Fedora Core 5. The SCIM language input framework provides
an easy to use interface for inputting many different non-English
* For all of the dirty-details, see the full release notes at:
K12LTSP includes LTSP version 4.2. LTSP-4.2 offers lots of great
* Redesigned local device support based on ltspfs and lbus. Currently,
USB Memory sticks, USB CDRom, IDE CDrom and floppy drives are
supported. With local devices enabled, when you insert a memory
stick or a CDRom, an Icon appears on the desktop that is browseable.
Remove the memory stick or CDrom, and the icon disappears.
* We've reduced the amount of memory needed on a thin client by
about 7mb. This is really significant for low-memory machines.
* Updated to the 18.104.22.168 kernel.
* Swap over NBD. We've used NFS-Swap in the past, but that's not
available in the 2.6.x series kernels. We wrote a new ltspswapd
daemon that runs on the server, to provide NBD swapfile management.
* udev has completely replaced devfs. This causes a significant
speedup in the boot time, and better hotplug capabilities for
* SANE (Scanner Access Now Easy) is now included in LTSP, so you
can plug scanners into the thin clients, and access them from
anywhere on the network.
* Multi-head X - The ability to have multiple video cards and
multiple monitors connected to a single thin client. Very handy
for extreme programming, where you just need more space to open
up more windows.
* Faster client booting. We've really made some great progress here.
By switching from devfs to udev, and by making lots of improvements
to the startup scripts, we've decreased the boot time dramatically.
On our test workstations (LTSP T-170's from DisklessWorkstations.com),
we've gotten the boot time down to 22 seconds! That's 22 seconds from
pressing the power button, to having a graphical login screen.
THAT is fast.
* VNC module that can be used by Fl_Teachertool to Monitor or
Control a thin client. Note that is disabled by default. To enable
this feature, you must do the following:
1) Edit the file /opt/ltsp/i386/etc/lts.conf and uncomment
(remove the "#") from the following line:
X4_MODULE_02 = vnc
2) Now you'll have to make a password for the vnc-session. Run this
command as root:
3) Copy the password file into the ltsp-tree
cp -R -p /root/.vnc /opt/ltsp/i386/root/
