wolfantsomeone has installed 10.4 on an n900?02:39
persiaI heard a bunch of folks announce they were going to do that.  I've not heard thay anyone did.  It *should* work, as long as you use Nokia's kernel, but no guarantees.02:40
wolfantI'll try and see what happens02:42
persiaGood lcuk!02:43
wolfantthanks02:44

orbarron|nbnot sure if you anyone can help... but is there a way to switch from ubuntu to UNR easy? I would also like to switch back to ubuntu as well...06:47
persiaDifferent environments should be selectable as different sessions in the session manager.06:49
persiaIf they aren't, you may want to install more packages: for example, install "ubuntu-desktop" to get a desktop.06:49
orbarron|nbahh found it.. thanks06:56
Amit_KarpeWhen will lucid-armel-omap will released ??07:18
persiaabout 12 hours ago.07:19
persiaBut it's not an official release, just frozen snapshot images.07:19
* persia hunts a URL07:19
persiaWhich flavour did you want?07:20
Amit_KarpeAre you talking about this URL ??  http://cdimage.ubuntu.com/ubuntu-netbook/ports/daily-live/current/07:21
Amit_KarpeI want to test all :)07:21
Amit_Karpeu* or k* -- netbook07:21
persiaHrm.  Seems the images didn't get copied.07:21
Amit_KarpeGiven site is down saying --> "The connection was reset"07:22
persiaI suspect they need test reports and prompting of someone.  You can grab the "prerelease" images at http://cdimage.ubuntu.com/ubuntu-netbook/ports/daily-live/current/lucid-netbook-armel+omap.img or http://cdimage.ubuntu.com/kubuntu-netbook/ports/daily-live/current/lucid-netbook-armel+omap.img07:23
persiaYeah, the server is *swamped* with people downloading it.07:23
persiaWell, that and all the other images that are on cdimage instead of releases.ubuntu.com07:24
persiaIt should work if you're patient.  Alternately, wait a couple days for the excitement to calm down (although that's not as much fun)07:24
ograpersia, ports werent published yet07:24
persiaogra: Why not?07:24
ograshould happen soon07:24
persiaogra: imx51/dove netbook was published.07:25
persiahttp://releases.ubuntu.com/lucid/07:25
ograyes, they are on releases.u.c07:25
ograeverything that stays on cdimage.u.c wasnt published under thge release directories07:26
persiaAha!  And now it all makes sense.07:26
persiaAmit_Karpe: My apologies: instead of "About 12 hours ago", I should have said "Real Soon Now".07:27
persiaNote that there is no specific time involved in "Real Soon Now", but it oughtn't be that long.07:27
persia(mostly a matter of copying files to the right places at this point, I believe)07:27
suihkulokkiboohoo, LP #446552 was not fixed in lucid07:29
ubot4Launchpad bug 446552 in update-manager (Ubuntu Karmic) (and 3 other projects) "url_downloadable ignores proxy settings (affects: 24) (dups: 2) (heat: 138)" [High,Confirmed] https://launchpad.net/bugs/44655207:29
persiaIt wasn't?  It says it was.07:31
Amit_Karpepersia: Thank You. Lets wait till "Real Soon Now".07:32
persiaAmit_Karpe: If you like.  I'm absolutely sure the images will be bit-identical when someone gets around to copying them.07:32
suihkulokkipersia: I still see it contacting without talking to the proxy and the buggy code is using httplib is still there07:32
persiasuihkulokki: Please reopen the lucid task on the bug with documentation of your results.  It shouldn't do that.07:32
Amit_KarpeAs of now I am playing with Prebuil Lucid image. I am able to run that on BB.07:35
Amit_KarpeAnd  I am going to install netbook-launcher.07:35
ograinstall netbook-launcher-efl rather :)07:36
Amit_KarpeI had completed installation07:36
persiaIf you already have an image, you can upgrade to final with `sudo apt-get dist-upgrade`07:36
Amit_Karpeok07:36
Amit_Karpegreat.07:36
persiaNo point downloading *another* image and doing the installation again.07:37
ograor do-release-upgrade :)07:37
persiaogra: Does that work from milestone to final?07:37
Amit_KarpeLet me try netbook-launcher and then I will update you my results07:37
ograshould07:37
* persia has only done do-release-upgrade to get from one release to the next07:37
Amit_Karpenetbook-launcher required any gdm or lxdm ??07:41
ograyes07:42
ograalso dont install netbook-launcher you want netbook-launcher-efl07:42
Amit_Karpeok07:42
Amit_Karpethen now should remove  netbook-launcher and install  netbook-launcher-efl ??07:43
Amit_Karpewhile running  netbook-launcher I got this error -->  http://pastebin.com/ZgjbWzJR07:43
ogracannot open display means you have no X running07:45
ograinstall gdm first07:45
Amit_Karpeok07:45
Amit_Karpeogra: Should I install lxdm instead of gdm ? I think lxdm is very light ?07:52
ograno idea, i have never used lxdm07:52
ograyou surely could though07:53
Amit_Karpeor xdm ?07:53

slipshi09:32
slipsanyone tried building a lucid rootfs in rootstock and succeeded booting it in qemu?09:33
slipsI keep getting an error during boot saying "ureadahead main process (275) terminated with status 5", then the screen goes black after a few seconds.09:36
slipsI think plymouth has something to do with it...09:36
hrwlet me fetch proper kernel09:36
hrwbooting09:38
ogra_cmpcslips, status 5 is fine it just tells you it wont profile your disk09:39
slipshmm09:42
slipsok, then ureadahead is not part of the problem.09:42
ogra_cmpcright09:42
ogra_cmpcdo you use any console= option on your cmdline ?09:43
slipsi've tried a few. tty0, ttyAMA0,baud etc.09:43
ogra_cmpcthat will make plymouth switch off the splash09:43
ogra_cmpcmight cause the black screen you get09:44
slipsah09:45
loolmorning hrw09:45
loolwell morning all :)09:45
ogra_cmpcmorning lool09:46
slipsso it might not be plymouth either..09:48
slipsstrange this is that after the screen turns black, there's never any more output09:49
slipshowever, if I boot into runlevel 1, i get the console09:49

sijimike^ u there10:13
dmartlool: hi there10:28
dmartasac: hi10:31
dmartapw: lool suggested to me that you know something about the packaging of the userspace perf tools--- do you have a moment to look at a blueprint draft?10:35
loolhey Dave10:38
dmartlool: hi, I thought everyone must be hung over / having a lie in / travelling ;)10:38
asachi dmart10:38
amitkdmart: its back to work on maverick :)10:39
* dmart seems to have woken everyone up10:39
asacright. thats the pace of ubuntu ;) ... no rest10:39
* amitk is taking next week off10:39
asaclagger :-P10:40
dmartlool: Will had an initial stab at the profiling blueprint--- mind taking a look?10:40
dmart(Will = wildea01)10:40
wildea01hello10:40
looldmart: sure10:46
dmartIt would be good if someone from your end can add comments on the tool packaging and profiling frontends currently in use, would apw be the right person?10:47
apwdmart, i've packaged the kernel perf tool as its kernel version locked10:47
loolwildea01: heya10:47
wildea01lool: hi10:48
wildea01apw: currently it's only packaged for x86/amd64 afaict10:48
loolapw: So dmart is looking in what would need to happen to have it on armel as well I guess10:48
apwits not packages for armel cause its not supported on arm10:48
apwiirc10:48
loolapw: Also, there might be some kernel patches needed to get it working there10:48
loolyeah10:48
wildea01the patches are in 2.6.33 I think10:49
apwso likely we can enable it for M then10:49
dmartthat's what the blueprint is about :)10:50
dmartapw: would you mind having a quick look at the current draft to see if there's anything you would add?10:50
apwurl ?10:50
wildea01https://wiki.ubuntu.com/Specs/M/ARMDebuggingWithOprofileAndPerf10:51
wildea01I only just wrote it, so feel free to change it :)10:51
loolapw: Is the change to packaging a 2 minutes job that we just need to ping you about, or will you want patches?10:53
apwif this is already enableable in 2.6.34 then its a bit flip pretty much10:54
apwwildea01, the spec looks fine for a draft, i suspect the kernel work is a slam dunk but best to list it in case it isn't10:56
wildea01apw: okey doke, thanks10:57
dmartlool, apw: are there frontend tools in place for perf yet?10:59
looldmart: You mean graphical?10:59
looldmart: there are commandline frontends10:59
loolthe perf command in the perf-`uname -r` packages10:59
loolwell the linux-tools-xxx rather10:59
dmartIf there were gui frontends already available for other arches, we would want to ensure arm has them too10:59
wildea01lool: the only visual one I could see is perf timechart, and I didn't quite understand what I was looking at :)11:00
apwlool, right in linux-tools11:00
Amit_Karpeogra, persia : Thanks a lot you help. Please check snap of my running netbook-launcher-elf http://amitkarpe.posterous.com/ and video http://www.youtube.com/watch?v=SfdetzHGEcc11:01
loolwildea01: The spec looks ok, but keep the summary to a couple of sentences describing the goal e.g. "Providing perf and oprofile support for ARM"; move the list of work items to the Implementation section11:01
loolwildea01: But that's already more than you need for UDS, looks good!11:01
wildea01lool: thanks, I'll shift some of the summary down to the implementation11:02
dmartlool, apw, wildea01: ok, sounds like we have a blueprint.  Thanks for the help, guys11:03
ogra_cmpcAmit_Karpe, the images were moved, i updated the link on the wiki a while ago11:10
ogra_cmpc(and renames to the proper release names)11:11
ogra_cmpc*renamed11:11
Amit_Karpethx.11:11
Amit_KarpeShould do it again or just `sudo apt-get dist-upgrade` ?11:12
Amit_Karpeor or do-release-upgrade  ??11:13
ogra_cmpci meant that your blog entry points to the daily images11:13
Amit_Karpek11:13
ogra_cmpcyour system should be up to date :)11:13
ogra_cmpcthe netbook image is now at http://cdimage.ubuntu.com/ports/releases/lucid/release/11:14
ogra_cmpccalled buntu-10.04-netbook-armel+omap.img11:14
Amit_Karpeok, I will update it.11:14
* ogra_cmpc sighs12:07
ogra_cmpcnetbook-launcher-efl pulls in half of gnome12:08
* ogra_cmpc doesnt get why12:08
ogra_cmpcoh, silly recommends12:13
langabeHi, trying to launch a rootstock built karmic rootfs with ubuntu-desktop seed but init stops with -- udevd[570]: failed to create queue file: No space left on device --, any ideas?14:21
ogradid you pick a proper imagesize in the options ?14:26
ograoh, to slow :P14:26
apwogra, yo ... does lsusb work on your arm platforms15:46
hrwapw: why it should not?15:56
apwhave a machine here where it is not, but i think we have it nailed15:57
hrwworks for me on beagleboard15:59
hrwworked for me on many other arm devices too16:00
ograapw, usually works16:05
ograasac, so my minimal system running X, fbpanel, metacity, xterm and efl launcher consumes 27MB according to htop16:07
ograthough its indeed very limited in functionality16:07
amitkogra: on beagle?16:09
ograyes16:09
amitknice, I would be interested in that as dev environ. Do you have a seed?16:10
ograi started off bootstrapping a minbase chroot and then only installed very few bits16:10
ograno, but i can roll a tarball over the weekend16:10
ograthere is a ton of stuff thats still broken i surely miss a lot of bits16:11
ograthe complete system uses only 515M on disk currently16:12
ograso i should be able to tar that to 2-30016:12
amitkogra: just a package list would be great on the minimal chroot16:15
amitkno pressure though, after UDS is just fine :)16:16
ograoh, right, you are gone next week anyway :)16:16
ograi'll have something for you by uds for sure ...16:16
hrw~curse loop device16:26
ogra?16:29
hrwI got out of loop devices again16:31
hrwvm-builder uses loop devices and if it break then I need to umount that by hand16:32
ograhrw, help me inplement my spec then :)16:32
ograyeah16:32
hrwogra: url to it?16:32
ogra<-- not a big fan of the bloated vm-builder16:32
ograhrw, https://blueprints.edge.launchpad.net/ubuntu-arm/+spec/userspace-loop-mounting16:32
hrwogra: fuse do not have isofs?16:33
ogramy initial goal was to hev rootstock not require root16:33
ografuse might have iso but nothing for loop16:33
ograi want to be able to loop mount in my homedir without sudo/root16:34
ograand even preferably without using a loop device :)16:34
ogra(not sure thats possible but i didnt start researching yet)16:34
ogranbd could once do that, if you had started the nbd-server as a user you could mount an image as the same user16:35
ograbut sadly since it got deeper integrated in the kernel it has the same constraints as loop mounting16:35
