Hi :)
Installing is idiotproof, but a PITA for experienced users. It's not
nice that the installer does force me to install a bootloader and that
the clock is set to UTC. Using UTC is self-defeating, if we would
save e.g. BIOS settings by the BIOS, with the hardwareclock set to UTC,
the time would be wrong.

It's as expected that X settings are a disaster and that there's no way
to easily set it up correctly. The only refresh rate I can choose is
60.0 Hz, needed are > 75.0 Hz. The highest resolution to choose is
1024 x 768, wanted is a higher resolution. I don't expect that any Linux
distro will fix this. I only hope they never will drop the possibility
to set up a xorg.conf.

This thingy is evil crap. I hate this pay-for-apps-thingy. I'm using
Linux to avoid such crap. However, I installed Galculator using it. It's
painful slow and when I typed using Gedit, the Software Center opened
windows on top of Gedit and interrupted typing.
Anyway, as expected Galculator is in the menu "Acessories" and it's ok.
The default calculator ignores the "," on the German keypad, but
Galculator transforms the "," to the needed ".".

Done, before I continued I closed hdspmixer.

PA sink is created and connected.
The Poettering crap doesn't work, the RME card is not shown. Available
are only the 2 TerraTec cards, but those cards aren't connected to audio
gear, I'm using them for MIDI only.

I'm missing serious audio and MIDI tests ;). At least I like to add a
Jack MIDI latency test. First I rebooted again.

There's a problem with my RME card for current installs. There shouldn't
be xruns when running the latency test. This is a serious issue, but not
related to Ubuntu Studio Quantal RC, I also get them on Arch. Some time
ago I didn't get xruns with Debian testing. Only for the RME card I run
the test several times, because I know about this issue.
It's new that I get peak jitter > 0.9 ms and a serious issue too.

That's new, averaged jitter for the TerraTec cards should be 0.00 ms.
However, I suspect it's still ok. It should be ok to run the test for
one TerraTec only.

That test result is "normal". USB MIDI interfaces can't be used to make
music. Those interfaces are ok for bulk dump. The peak MIDI jitter isn't
ok, but "normal", this isn't a Ubuntu Studio Quantal RC issue.
