Prologue: "Peak MIDI jitter: 12.73 ms (8 frames)" > 12 ms jitter is insane, OTOH I wonder about the 8 frames only.
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. > "Desktop Test > Boot into Ubuntu Studio and login as user > Note: make sure to reboot after any software updates before testing, > even if not asked to. > Confirm the screen resolution is as expected" --- 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. --- > "Open Ubuntu Software Center and install applications you would like to > use > Ensure the applications are installed correctly and appear in the > applications menu" --- 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 ".". --- > "If you have a USB drive, plug it in > Check that the USB drive is mounted and that you can open files from > it" --- It's ok for my USB stick. spinymouse@qrc:~$ cat /media/spinymouse/INTENSO/Ubuntu_Studio_USB_stick_test.txt Ubuntu Studio USB stick test :) --- > "Note: Ubuntu Studio does not mount any hot plugged devices by default. > If you have a DVD or an audio CD, insert it > Check that the disk is mounted and that you can open and/or play > files/tracks from it > Log out, shutdown or restart > Confirm the session is terminated properly" --- Skipped --- > "Applications > Click the "Ubuntu Studio Information" item menu in the menu. > Does all the links included in there work?

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. spinymouse@qrc:~$ jack_midi_latency_test -m 3 -s 8192 -t 5 "system:1-1 HDSPMx579bcc MIDI 1 1 out" "system:1-1 HDSPMx579bcc MIDI 1 1 in" Waiting for connections ...
