So i am back.
Installing 12.04 (snapshot: LMCE-1204-20140121095528629.iso) was "smoother" than i thought.
a few obstacles that occured:
1.)
bevor the first reboot it seemed to hang at 90%. i switched to a text conole and it magically resumed. maybe it was just superstition and it would have gone further anyway ....
2.)
the core/hybrid needed direct access to the internet as it was mentioned here somewhere in the forum. otherwise it got stuck in a reboot-loop due to not detecting the network.
after the installation i can now put a router between core and the internet and network is fine.
3.)
my tv-usb-card win-tv-nova is recognized and added several times like it is in 10.04.
4.)
Z-Wave:first my aeon labs z-stick was not detected. today i have put another usb-stick into the core (tricklestar 300zw-eu). that wasn`t recognized either but after switching back, the aeon stick got detected and added.
buti cannot control any lights.
They show up in the web-administration-page but turning on/off has no effect.
andthe smoke detector is still not recognized correctly (generic tuner).
The new grub recognized my 10.04 installation. so after changing the default grub entry, i now have a nice dual boot.
one stable sysem and one to fiddle arround.
Video and audio is doing fine.
Again thanks!
I wouldn`t have thougt that 12.04 has come that long way already.
The smoke detector is not so important. it is just a nice thing to have that linked to the "matrix".
