| artisan | rlameiro: still alot of xruns | 00:02 |
|---|---|---|
| rlameiro | well, try the rt kernel then | 00:03 |
| rlameiro | maybe it is something with locking memory | 00:04 |
| rlameiro | try to fiddle with the memory lock settings on qjackctl and ubuntustudio controls | 00:04 |
| artisan | rlameiro: k. I will try! | 00:05 |
| artisan | thx holstein & rlameiro | 00:05 |
| artisan | cu | 00:05 |
| rlameiro | np | 00:05 |
| RPG-Master | Anyone here have experience with using non-wacom tablets with Ubuntu? | 01:21 |
| Blank__ | >.< nvidia won't work with the rt kernel | 02:45 |
| Blank__ | not even running the installer script from the nvidia site | 02:45 |
| arghh2d2 | howdy yall, does anybody remember there was a bash script that would check your system for a bunch of possible optimizations and list urls to wiki's if you needed em? is that still around? | 03:04 |
| arghh2d2 | ubuntustudio channel is rockin as usual i see | 03:24 |
| ScottL | RPG-Master, i've only seen one other guy here asking about the wacom tablet | 03:27 |
| ScottL | you might check ubuntu forums though | 03:27 |
| RPG-Master | ScottL: nevermind, found a driver package called WizardPen on launchpad :) | 03:29 |
| RPG-Master | works | 03:29 |
| ScottL | superb! | 03:30 |
| artisan | hm, tried -rt, -realtime as well as -lowlatency .. with all of them I get starting jackd, as well as mixxx: "Cannot lock down memory area (Cannot allocate memory)" | 11:02 |
| artisan | the corresponding settings for @audio are set in /etc/security/limits.d/audio.conf (and only there, commented them out in /etc/security/limits.conf) | 11:03 |
| artisan | rtprio 99, memlock 1160659 & nice -19. the user is in group audio .. I am really running out of ideas :) | 11:04 |
| artisan | . | 11:11 |
| astraljava | artisan: I have only one suggestion due to lack of experience: Have you rebooted? | 11:14 |
| artisan | astraljava: sure, I had to, to test the different kernels :/ | 11:15 |
| artisan | I don't see where things could be wrong .. | 11:16 |
| astraljava | artisan: Just making sure. :) Like I said, I don't have much experience with realtime (yet), so I can not give further advice. Stick around, and ask again in a few hours, and hopefully someone knowledgeable will come around. | 11:16 |
| artisan | :) | 11:16 |
| astraljava | artisan: Alternatively, you can post to ubuntu-studio-users@ or ubuntuforums.org Ubuntu Studio section. | 11:17 |
| astraljava | artisan: Hmm, wait, this page: https://help.ubuntu.com/community/UbuntuStudioPreparation suggests @audio - memlock unlimited, you had an integer instead of unlimited. | 11:21 |
| astraljava | artisan: Also, I believe nice is considered outdated and obsolete re: realtime. | 11:22 |
| artisan | astraljava: actually it is more clever to give like ~80% of memory to the audio group instead of unlimited. | 11:23 |
| artisan | hm, what do you mean by nice being outdated? have a pointer to some docs? | 11:23 |
| astraljava | artisan: I understand. Hmm... let me find a reference. | 11:24 |
| astraljava | artisan: http://linuxaudio.org/mailarchive/lau/2010/3/5/166445 | 11:25 |
| artisan | astraljava: kool! good to know :) | 11:27 |
| artisan | hmm, jackd even as root doesn't start with prio RT | 11:29 |
| artisan | is that common? | 11:29 |
| astraljava | artisan: I have no idea. What's your jackd start command? | 11:36 |
| artisan | /usr/bin/jackd -R -t1000 -dalsa -r48000 -p512 -n3 -D -Chw:1,0 -Phw:1,0 | 11:36 |
| artisan | but I just saw that it complains about acquiring RT privileges as well. | 11:37 |
| artisan | but what else then editing /etc/security/limits.d/audio.conf can one do?? | 11:37 |
| astraljava | JACK 0.117.0 released: jackd now runs in realtime mode by default. the use of -R is no longer necessary. Use -L to run in non-realtime-scheduling | 11:39 |
| astraljava | artisan: I saw a mention that -R actually reverses the realtime privileges. | 11:39 |
| astraljava | artisan: But jackaudio.org doesn't support that. | 11:39 |
| artisan | ok, thats why qjackctl isnt using -R anymore :) | 11:40 |
| astraljava | artisan: Try leaving it out anyway. | 11:40 |
| artisan | same result | 11:40 |
| artisan | no RT prio | 11:40 |
| artisan | Cannot use real-time scheduling (RR/10)(1: Operation not permitted) | 11:40 |
| artisan | :/ | 11:40 |
| astraljava | artisan: Which kernel have you booted in currently? | 11:41 |
| artisan | 2.6.33-1-realtime #1-Ubuntu SMP PREEMPT RT i686 | 11:42 |
| astraljava | Damn. I'm running out of suggestions. Keep trying on this channel, or like holstein would say, go to #opensourcemusicians, there are some pretty educated folks there too. :) | 11:43 |
| artisan | k, thanx for trying astraljava :) | 11:44 |
| astraljava | artisan: But if you find help there, or elsewhere, please do post the solution on the forums or the mailing list, spread the word you know. :) | 11:44 |
| artisan | I will :) | 11:44 |
| astraljava | Thanks. :) | 11:45 |
