Hello,
we are using LTSP with Edubuntu 12.04 for some years now and it works
fine except a
shutdown problem, we had over one year ago with our Zotac Zbox clients.
We had fixed this problem by using a patched version of LDM that is
starting "poweroff -fp" instead
of "poweroff" and also with an old "ltsp-shudown.conf" from Edubuntu
11.xx, that also forces
to use "poweroff -fp". The ltsp-shutdown.conf was needed to fix the
shutdown problem, when using Epoptes to power off the clients.
This Workaround was working fine with the Zotac Zbox, but we have now
some Shuttle DS437 clients, that needs a newer Kernel version to run
smoothly.
After updating our LTSP images to Kernel 3.8.x all clients hangs again
on shutdown when using the Epoptes management tool to poweroff the clients.
The only way to successfully poweroff a client is to use the patched LDM
version with "poweroff -fp".
After switching back to kernel 3.5.x, the shutdown problem is gone, but
the Shuttle DS437 have some graphics problems and are running very slowly.
Can anybody help me to fix this shutdown problem when using a newer
Kernel version?
It looks like the ltsp-shutdown.conf have no effect anymore when using
Kernel 3.8 and later,
but i don't know why.
Thx
