Thanks Brian, I think you should put your path into a How to. may to append to the UbuntuStudio preparation, I think Everyone should apreciate it very much Thanks for sharing <div class="gmail_quote"> 2009/11/5 Brian David <<a href="mailto:beejunk@gmail.com">beejunk@gmail.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Karmic's been out for about a week now, and I've finally gotten everything to work well. Here are my experiences and thoughts, in case they are useful to any of you. First, my hardware: Macbook, first generation 2.0Ghz processor 2Gb memory Presonus Firepod audio interface I was excited to discover that Ubuntu Studio can be installed from a USB stick. This was very important to me since my Macbook's CD/DVD drive is broken. I had attempted to do this in the past and failed, but this time around the following steps worked for me: 1) I used Gparted to format a 4Gb USB stick to FAT32. 2) I then used Gparted to check and verify the drive. This is crucial, becuase for reasons I cannot explain, the USB stick would not work if I did not run this check. It took me many days to figure out this odd little quirk. 3) I then used the USB Startup creator that can be found on a standard Ubuntu install. I highly reccommend installing from a USB stick. I found it to be far quicker and more reliable. After install, I booted up. Setting up my wireless card via the Network tool went off without a hitch, which was a relief. Everything else seemed to work well, with the exception of my brightness keys, which do not work at all. This is a major improvement over Jaunty, though, where the brightness keys would do crazy and random things. On a side note, I like the fade-in on the Ubuntu Studio splash page, and the artwork and GTK theme are, as usual, beautiful. So far, so good. Now to set everything up for audio recording. I discovered that the 'Audio' group already existed, and that my account was already in that group, which was something I had to set up manually on Jaunty. The 'Video' group also already existed, but my account was not yet in that group. I use a firewire audio interface, and so it is necessary for me to put my account in the 'Video' group, which I then did. Next up, I opened Ubuntu Studio Controls and adjusted my settings. This is where the first important glitch occurred. After applying my settings, I viewed the /etc/security/limits.conf file to make sure everything had worked. I discovered that Ubuntu Studio Controls had NOT inserted my 'nice' settings. I attempted to use USC a few more times, but to no avail. I then just set 'nice' manually. I rebooted, opened up the JACK Control and took my Firepod for a spin. The good news is that JACK connected right away using FFADO, and there were none of the infamous permission problems that I've had before. The bad news is that the performance was amazingly poor. Even though I was only using 3% - 5% of my processor power, I was still getting an x-run every ten seconds or so, using the exact same settings that worked perfectly under Hardy. After much Googling, the solution to my problem was to be found on this page: <a href="http://alsa-project.org/main/index.php/Low_latency_howto#PAM" target="_blank">http://alsa-project.org/main/index.php/Low_latency_howto#PAM</a>. In particular, the directions under the 'Thread Priorities' section solved my issues. This was definitely something that I did not have to do under Hardy. I wrote a small script to set all these priorities quickly, so it's not too much of a hassle. Still, I was suprised to find that I had to do this at all and that it was not mentioned on any other how-to I had read (such as the much referenced Ubuntu Studio Preparation page). In the end, I had a system that was as rock solid as Hardy, even if it took some time to figure everything out. But that's usually how it goes with a new OS. All in all, the basic desktop experience of Karmic is the best I have seen to date. Also, the new fonts package makes me VERY happy. However, when it comes to pro-audio, we are still far away from a user-friendly, no-hassle experience. However, once you get the system working, the performance is impressive. Thanks for all your hard work everyone! I look forward to finishing some serious projects on Karmic. -- -Brian David -- Ubuntu-Studio-users mailing list <a href="mailto:Ubuntu-Studio-users@lists.ubuntu.com">Ubuntu-Studio-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users</a> </blockquote></div> -- Fagote / Contrafagote Bassoon / Contra-bassoon <a href="http://myspace.com/ricardolameiro">http://myspace.com/ricardolameiro</a>
