| ailo | ronj: Ronan, right? | 01:14 |
| ronj | ailo, yup. I agree with your email, maybe the perf improvements with -lowlatency occur on heavy setups with lots of i/o | 01:15 |
| ronj | could use some more testing | 01:15 |
| ronj | well that was what somebody suggested at some point in the mailinglist | 01:15 |
| ronj | ailo, also could you add your results to the table? | 01:16 |
| ailo | Me and rlameiro are about to create a test program using a script and puredata, which hopefully can be useful for finding that out. | 01:16 |
| ronj | even if it's only qualitative | 01:16 |
| ronj | oooh great :) | 01:16 |
| ronj | excellent | 01:16 |
| ailo | I will post my results too. | 01:17 |
| ronj | share it the mailinglist once it's done, i'll be happy to run it on my system | 01:17 |
| ronj | ok | 01:17 |
| ailo | Will do | 01:17 |
| === detrate` is now known as detrate | ||
| ailo | ronj: I'm not able to boot the latest -lowlatency. All I need is the image and the headers, right? Why is it not booting? | 01:31 |
| ronj | ailo, right, only -image and -headers, seems the linux-lowlatency metapackage isn't up2date (stayed at .37) | 01:37 |
| ronj | for me it boots fine | 01:37 |
| ronj | any error message? | 01:37 |
| ailo | Mine just stops and reboots | 01:37 |
| ailo | Just after Grub | 01:37 |
| ronj | oÔ | 01:37 |
| ailo | Maybe I should reinstall, and try again | 01:37 |
| ronj | hm and have a look at the log | 01:37 |
| ailo | Grub log? | 01:38 |
| ScottL | rlameiro, how was the install failing on the ubuntustudio ISO image? | 01:39 |
| rlameiro | tasksel menu -> choose packages --> error on install | 01:40 |
| rlameiro | after that it seds me to the list of the install i continue trying with different choices, even without selecting any task | 01:40 |
| rlameiro | and the same happens | 01:40 |
| rlameiro | eventualy i quit | 01:40 |
| ScottL | rlameiro, did you have the lv2, ladspa, and dssi plugins each as a separate choices during selection? | 01:41 |
| ScottL | rlameiro, not that you picked them, just were they there as separate choices, as opposed to how they are usually which is all three together as one choice | 01:42 |
| rlameiro | I had lv2, dssi separated | 01:42 |
| rlameiro | yest they were separated | 01:43 |
| ronj | rlameiro, ScottL btw I tried todays iso and it installed fine with all the audio packages checked | 01:44 |
| ronj | (all except video and graphic) | 01:44 |
| rlameiro | hummm | 01:44 |
| ScottL | i am planning on talking to cjwatson tomorrow while i am at work about this | 01:44 |
| ailo | I'm guessing I get better luck with /var/log/boot, but I had to enable logging from /etc/default/bootlogd | 01:44 |
| rlameiro | i tried 29th build | 01:44 |
| rlameiro | AMD64 | 01:45 |
| ronj | mine is todays/i386 | 01:45 |
| rlameiro | letme rzync it | 01:45 |
| rlameiro | ronj: real hardware or VM? | 01:46 |
| rlameiro | rsynced | 01:47 |
| ailo | I needed to reinstall the -lowlatency image. I forgot to install the headers first and booted. After that installing headers did not change the boot problem, but reinstalling the image did | 01:48 |
| ronj | rlameiro, real hardware, dell vostro v13 | 01:49 |
| rlameiro | ok | 01:50 |
| ScottL | ailo, in response to the email: i expect the reason i say such a dramatic change between -generic and -lowlatency is because i was the old -generic kernel with the cgroups problems where i couldn't get -rt privileges | 01:52 |
| rlameiro | reboot time, cd stuck on the slot.... DVD RW not reliable yet | 01:52 |
| rlameiro | lol | 01:52 |
| rlameiro | cya soon | 01:52 |
| ailo | ScottL: I can almost swear that I had two different results on the same kernel, within two days time. Maybe I'm imagining, doesn't matter. Now, I'm getting good results. Seems like the Desktop is faster on the newest kernel, both on -generic and -lowlatency. Just a feeling :) | 01:54 |
| ronj | ScottL, could you test with todays -generic, with the cgroups stuff sorted out? | 01:57 |
| ronj | I'm updating the table | 01:57 |
| rlameiro | where is the table? | 01:57 |
| ronj | rlameiro, https://wiki.ubuntu.com/RealTime#Natty%20Benchmarks | 01:59 |
| rlameiro | ronj: thanks | 01:59 |
| rlameiro | ok, rebooting to test it out... | 02:03 |
| rlameiro | i will come shortly :D | 02:03 |
| ScottL | ronj, i should be able to test it by tomorrow evening | 02:05 |
| ronj | yay :) | 02:06 |
| ailo | I get identical performance and behaviour from the two kernels, from what I see | 02:07 |
| ailo | 2.9 ms on both | 02:07 |
| ailo | I can even push it to 1.45 on both, if I don't do anything while Ardour is playing or recording. | 02:10 |
| ailo | (zzz) | 02:13 |
| ronj | interesting | 02:14 |
| rlameiro | ok tasksel menu now | 02:23 |
| rlameiro | hummm :D | 02:24 |
| rlameiro | it seems its working | 02:24 |
| ScottL | rlameiro, did you still have the fragmented plugin selections? | 02:24 |
| ScottL | we did get the -video metapackage cleared earlier | 02:25 |
| rlameiro | yes :) | 02:26 |
| rlameiro | i selected lv2, dssi, tone generation and recording | 02:26 |
| rlameiro | i think | 02:26 |
| rlameiro | ScottL, can it be installed later as a metapackage? | 02:28 |
| rlameiro | well install will take some time, i think i will watch a docu | 02:29 |
| ronj | ScottL, need iso testing on -video? | 02:30 |
| ScottL | rlameiro, yes, it can be installed later as a meta package | 02:50 |
| ScottL | ronj, i don't think we need anything specifically tested, it was that the package wasn't building correclty before because a package had been removed from the repository | 02:51 |
| ronj | k | 02:51 |
| ScottL | the seeds were updated for the video metapack age and the package began to build correctly once again :) | 02:52 |
| rlameiro | hey!!! why does it try to run unity??????? | 02:58 |
| rlameiro | lol and on top crashed the system | 02:59 |
| ScottL | rlameiro, remember, when you login you must pick "classic desktop" session instead of "ubuntu desktop edition" | 03:00 |
| rlameiro | lol, too late | 03:00 |
| ScottL | i have a patch attached to the bug for this but it hasn't been uploaded yet | 03:00 |
| rlameiro | now it doesnt boot | 03:00 |
| ScottL | rlameiro, reboot and change the selection | 03:01 |
| rlameiro | well it boots but dont start.... | 03:01 |
| rlameiro | let me try again | 03:01 |
| rlameiro | nope.... it stops before the login window | 03:02 |
| rlameiro | weird... | 03:02 |
| rlameiro | i will wait to see if it is thiking on RAM | 03:02 |
| rlameiro | rebooted 3 times | 03:06 |
| rlameiro | crashed on all of them | 03:06 |
| rlameiro | tried to go using the recovery failsafeX same problem | 03:07 |
| rlameiro | what can i do? | 03:07 |
| rlameiro | maybe there is some conf file i can edit for the boot? | 03:07 |
| rlameiro | ScottL, do you have any idea how i can fix it? | 03:13 |
| rlameiro | on the cli | 03:13 |
| rlameiro | I had a segmentation fault on Xorg server | 03:18 |
| rlameiro | well i made an apt-get upgrade and disconnected the mouse and it worked | 03:23 |
| rlameiro | lol | 03:23 |
| rlameiro | i connected the mouse while logging in the first time | 03:23 |
| ScottL | rlameiro, glad you managed to get it working then :) | 03:28 |
| rlameiro | well, tested usb with generic kernel | 03:49 |
| rlameiro | tomorrow will test firewire | 03:49 |
| rlameiro | cya | 03:49 |
| ailo | ScottL: http://en.flossmanuals.net/ There's a few multimedia manuals there. Check it out. | 11:14 |
| ailo | Quite a lot of Video manuals. | 11:15 |
| scott-work | cjwatson pointed out what the problem probably is for the ladpsa/lv2/dssi task during installation | 20:26 |
| scott-work | apparently there is a mishandling of the comma-space separator for the audio-plugins | 20:28 |
| scott-work | i'll see about making the changes tonight | 20:28 |
| scott-work | TheMuso: would you be able to update the meta packages again? | 20:28 |
| scott-work | just for the record, this is the offending line: Task-Description: LADSPA, LV2, and DSSI audio plugins | 21:19 |
| scott-work | specifically the use of commas | 21:19 |
| scott-work | TheMuso: nevermind, i bugged (read: begged) cjwatson and he said updating the metas is uneccesary and even updated the sees and will rerun his tasksel script shortly | 21:43 |
| scott-work | this should fix the tasksel for alpha2 :) | 21:43 |
| scott-work | s/sees/seeds | 21:49 |
